What our reviewers found

Pros

Owners mostly love how easy it is to use and how well they sleep on it, and it features some impressive movement options controlled via remote or app.

Fair price point given the amount of motion available.

Plenty of compatibility with mattresses in the range.

Cons

Price point, while reasonable given the quality of components, is still quite pricey, which considering the functionality of adjustable beds is sometimes more utilised in the frail and disabled, may prove a barrier to entry for those on a fixed income.

The Sleepmotion 400i Adjustable Platform Bed Frame is a highly advanced bed frame that offers a range of features designed to improve your sleeping and lounging experience. With 3 adjustable areas (head, lumbar, and feet), users can easily find their ideal level of comfort and support while lounging or sleeping. The bed frame can be controlled wirelessly using the included remote or through the Napp by Dreams app, making it easy to adjust the bed to your desired position.

One of the standout features of the adjustable platform is its Zero Gravity technology, which helps to ease pressure points and improve circulation. This technology, combined with the bed's 2 massage units for the back and feet, allows users to fully relax and unwind. The bed frame is also sturdy and well-constructed, with metal legs and a reinforced base, and it has a weight limit of 355kg (including the weight of the mattress).

In addition to its functionality, the adjustable platform is also stylish and can be used on its own or dropped into one of Dreams' Sleepmotion compatible bed frames. A matching headboard is sold separately for those who want to complete the look.

Sleepmotion 400i Adjustable Platform Bed Frame

Owners mostly write about how easy the 400i is to use and how much better they sleep on it. The Zero Gravity setting comes up again and again: "Very easy to use, I love the zero gravity setting", one owner wrote, and another said "my lower back pain has completely gone". Plenty bought it for mobility or health reasons and say that raising the head end makes it easier to get out of bed. The anti-snore position gets a few mentions too, and owners who bring up the price tend to call it worth the money.

The massage units get more praise than complaints. Owners like them for aching legs and backs, but noise is the complaint that comes up most: "I find the massager far too noisy", one wrote. Owners complain about the app as well. One pointed out that "the app is only available on Apple and not Android", and another said it stopped working after a year. The frame is heavy ("really heavy to turn, even for 2 people", as one owner put it). Owners with very thick mattresses say the mattress shifts or doesn't bend fully with the base.

Overall, the Sleepmotion 400i Adjustable Platform Bed Frame is a highly-functional and comfortable bed frame that is well worth considering for anyone looking to upgrade their sleeping and lounging experience.

We bought this unit to fit inside our existing oak framed bed and needed some careful measuring to make sure it fitted OK, so we visited the showroom to carefully measure up. The staff there were extremely and we were able to fully test it out as well and were sure it was the right thing for us, particularly with the extensive features available. We had been looking at cheaper slatted type adjustable beds but were advised the solid base type were superior. Having ordered it and set a delivery date right at the start (which was nice) we were later offered the opportunity to bring the delivery forward so we only had to wait around 3 weeks to get the unit. The delivery went smoothly with the strong delivery guys taking the bed sections right where we needed them - they were gone within a few minutes of their knock on the door. Assembly was easy, though it did take two of us to flip the assembled bed over as it is quite heavy. The wooden bed frame had been slightly modified to accommodate the unit but it slotted in perfectly and looks great. We reused our existing Ergoflex mattress, though we had been prepared to change it if necessary as Dreams could not promise it was suitable. So the unit works perfectly and fulfils all its promises, though we have yet to use the massager - my wife will no doubt benefit from it when she gets a bad back. The only slightly disappointing aspect was that the three 'memory' buttons on the remote control are not programmable. In use, we only normally use about three positions outside the preprogrammed 'TV', 'zero G' and 'Flat' buttons so if the M1,M2,M3 buttons could be set up by us, it would be easy to go straight to the inclination required. We are both normal height or perhaps a bit shorter, and I was surprised to find that, with the back tipped up for watching, our feet were right up against the end of the bed. I imagine long legged people would suffer a bit with this Those minor niggles aside, we are extremely pleased with both the product and the service from Dreams - 5 stars well deserved!

Comes well packaged in two large boxes. Two people recommended to move, unbox and put the two halves together. The suppled instructions are good enough and there's also a YouTube video from Dreams that's really good. Once bolted together connecting the cables is super easy as they are colour coded and also not interchangeable. Each of the legs are two pieces giving a six inch or nine inch option. Initially I went for the nine but that makes for a really high bed - good if you're six foot or above. I've refitted the legs with just the six inch sections. The range of motion once you're up and running is fantastic and the remote control is backlit so you can see what you're doing. The massage options are really good with three levels for each section. There's also a lumbar support which is really useful. There's an app for your phone and that is my only criticism really as it's trying to be a "health and lifestyle" app rather than a simple phone based remote control.

This review is for the 400i bed frame and the Tempur Sensation Elite together. Because the combination just doesn't work properly. We were sold these together, in the store, but we were only able to try them separately, so had no idea there would be a problem . The mattress is too thick and dense to bend with the bed, so the foot end doesn't drop with bed frame, when knee area is raised (as it should, as shown in the ad. photo). There are gaps between frame and bed -- I have photos. A second issue is that we were told clearly that this model is 197cm long, because more length is needed with the head end raised. The salesman contrasted this with the 200i at 190cm.This isn't true -- it is a standard 190. Luckily, I am short so it's OK for me, but the frame was definitely mis-sold. Not impressed. We relied on help -- I'm going through chemotherapy and needed accurate guidance to buy on the day.

Due to a progressive collapsing back and legs issues I thoroughly checked the market and found the only bed that matched my needs was the Sleepmotion 400i a strong frame which allows me to get into every position that I need, legs up to help my blood circulation to flow easily and the zero gravity position which I find a very comfortable sleep, waking up without any back pain issues. There are many other positions and massage facilities that I use to help me relax. My only negative I have is they don't do the Sleepmotion 800i as a single bed. In the near future I will be buying a 2nd Sleepmotion 400i single bed so I can attach the 2 single beds together to make a super king size that can operate independently of each other as I need to sleep in the zero gravity and my wife to be in anti snoring position for us to be blissfully close and happy again.

It's well made and very heavy, the remote control is simple and straighforward, it lights up when you select one of the options it doesn't stay lit for very long, this could be annoying in the dark, after a few days you remember where all the options are, if this is an issue then you could just use your mobile phone. The massage option is nice has 3 levels of intensity, and I can now sit up and read without having to fight my pillows, I found a slightly flatter pillow was more comfortable when using the head in a raised position, my only negative is the bed feels a bit warmer for my preference, and you have to move your bedside table when you raise the bed head or you won't be able to reach it, overall I am sleeping better and I'm happy with the bed, maybe I will try some bamboo bedding to help cool the bed down.

I am disabled and have severe arthritis finding getting out of bed particularly difficult. I also have to use 2 pillows under my knees to try to get comfortable in a conventional bed. I decided that it would be a huge benefit for me to have a bed which helps me sit up to help get out of bed and allow me to sleep without pillows under my knees. To say I'm delighted is a huge understatement! I have never had such a comfortable bed allowing me to have the most comfortable and most restful sleep ever. I can't reccomend this bed highly enough. If you have problems getting out of bed or have arthritis in your spine, hips and knees, or you spend a lot of your time in bed please get this bed. I can guarantee you won't be disappointed.

Outstanding purchase, i struggle to get out of bed in the morning when i raise the bed its just like stepping out so simple ,and is superb to watch the tv ,with the bed sitting me up,there are times when i just want to lie a lot longer, and i put the massage on its so comforting.the mattress is soft to medium,what a brilliant sleep, you get what you pay for all is pure quality, my only regret is i wished i bought it a long time ago,but you cant turn the clock back.i am a very happy customer and a big thank you to dreams and to the lovely girl in dreams shop in Stirling that had the patience of a saint,to might shure she sold me the perfect bed for myself and my wife,well done.

After struggling with getting a good night's sleep due to injuries i read about the sleepmotion range. After visiting dreams and discussing my needs with a salesperson and trialling the bed we decided to putchase the sleepmotion 400i. The company kept us up to date with emails regarding delivery, the guys that delivered and set up the bed were first class, quick curteous and professional. With a certain amount of trepidation we tried the bed on the first night and had the best night's sleep in absolute ages, and have continued to sleep completely comfortably since. Cannot fault the bed or the company in any respect, very highly recommended

The bed looks very modern and sleek and you would not know it is an electric bed. Good range of movement and easy to operate. The 400i is the mid range option but does almost everything the more expensive 800i does. I also like that the legs are not on each corner ( just inside the frame which means there is no chance of stubbing you toes on them. Easy to hoover under the bed especially if you have the extra leg height fitted on delivery, which the brings the bed up to a more standard height. Remote sometimes takes a few presses to register. Extended warranty is good value giving 8 years cover on the electrical mechanisms and bed frame.

This bed is great and much more affordable than the older Temperpedic/Posturepedic bed I had. I also appreciate that, as heavy as it is, it's considerably lighter-weight than the old bed, so I can move it around the bedroom if I feel like it. The mattress is comfortable and breathable, and sometimes I feel like I can spend the whole day in bed (and I have). The reason for 4 rather than 5 stars is that when the mechanism is flattening, the top portion of the mattress slams down a bit instead of staying/meeting with the base smoothly, so it's a bit jarring but something I'm sure I'll get used to.

An excellent product and well informed by staff prior to purchase, the bed works the way it should and is far superior quality than the others i tried and researched. I have used it for over a month now and all i can say is that i have never slept this well in years, having my feet slightly raised has definatley helped with my poor circulation and prior discomfort. This bed is heavy and i would recommend the delivery team to unpack and install as i did. The team were great and even explained the working of the bed and remote and also took all packaging away. Excellent service - well done

As we are retired now we decided due to health reasons to purchase an electric bed. In the shop we went for the 200i on the sales person recommendation. However upon checking the website decided to upgrade to the 400i this has the back and leg massager integrated, and so glad we did. My ife spent a lot of time standing in her job and this allowed her to have the bottom half raised to aleviate pressure on her legs. It was also ideal for her back . If you are considering a new bed i cannot recommed this bed more highly. PS i think the wife is superglued to the bed after a month.

I was recommended by friends who had bought a similar bed fromDreams, to go and visit their showroom. The service was friendly and professional, no rush and plenty of opportunity to ask questions and look around. I also visited other stores offering similar beds but in my opinion the one in Dreams seemed to be of a superior quality.After buying and using this now for a couple of weeks I know I chose well. It has reduced my usual physical problems with sleeping, and gives me the rest I have long since despaired of achieving. Incidentally the delivery and installation was excellent

I love the 400i, I don't think I'll ever sleep on a flat mattress again, as I now prefer the head and foot ends slightly raised. I always get a great night's sleep, with no aches or pains. The mattress is less heavy than my previous flat mattress so much easier to rotate, though it doesn't need to be flipped over, which is also a benefit. The only improvement to make would be side supports (similar to the foot end stop) for the mattress to stop it moving sideways. The remote and smartphone app make the motion easy to control and give options. Great product, thanks.

I purchased the 200i for my elderly mother and I saw the difference the bed (and mattress) made to the quality of rest and sleep she had. I had to treat myself and chose the 400i....WOW! I hadn't realised it had the vibrate option, but this bed is definitely the best piece of furniture I have ever purchased. The Zero Gravity option is excellent after a hard days work, it allows the body to relax and the Lumbar feature assists in aligning me....I love this bed and don't see me ever purchasing a non adjustable bed. This bed was designed for me in mind...dreams do come true!

I purchased this adjustable bed because I suffer from severe back pain and sleeping in a regular bed was very difficult. I can adjust the new bed to any position to make the bed comfy for me. It takes the strain off my back. It's like a hospital bed but it looks like a regular bed including having a head board though this is an extra. I am definitely more comfy when I am in bed now. I couldn't comment on the lumbar spine adjustment because my lumbar spine is painful and I prefer to have no pressure on this part of my body. I would definitely recommend this bed.

Best bed ever, I have fibromyalgia, in pain and can`t sleep but this bed eases all that with the sprung mattress they sold to me at the same time. I`d bought so many beds cheaper hoping to find the right one, should have just saved my money in the first place and bought this. Its hard wearing, takes a lot and I mean a lot of weight and the electrics are quiet and it glides smoothly into place. The vibration, massage settings are an added extra, love the lumbar support, I needed that. Thankyou Dreams for making my life so much better. Sweet dreams xx

Love the fact that you can adjust the bed. Very good for reading or if your legs ache and you can lift them up. The massage is good but because our mattress is really thick it is not very intense. Easy to put together and height adjustable. The best experience for us was in the sales room (Knaresborough) we were there a long time as buying a bed is a big deal for us and the chap was ever so patient. He was good humoured as well and made us feel really comfortable. I dont think we would have considered this base without his input

Quality build, metal frame silent motor and ease of use are all things I bought this bed for. What I wasn't expecting was the comfort it gives me from my crippling back pain and arthritis. The massage feature of the head and foot areas are just a pleasant extra and the lumbar support adds extra support when head rest is lifted. The memory buttons on the control is another welcome addition, knowing you can go back to the position you were last comfortable in is such a bonus. All in all I'm very pleased with my purchase.

So pleased I bought this bed! I have copd so sleeping in an upright position is so much better for me. I did contemplate getting the 800i instead of the 400 but I stick with the 400 and do wish I had gotten the 800 for the neck positioning also but I'm very happy with the 400. My only gripe is what they call the "king size" 5ft is actually a standard double which is 4ft 6 inches! Had I known this I'd have went for the super king 6ft instead. But it's the best bed ever and it's made life much better for me.

The Dreams bed has a solid construction, variable head, leg and lumber support positions and the remote control makes it so easy to adjust my Dreams bed into the most comfortable positions, also the Dreams bed has a very modern streamlined shape.

This product was well under the price I expected to pay, the sales staff were very helpful and the delivery personnel were excellent, they assembled the bed talked me through the operations and disposed of my old bed in a efficient and timely manner. The bed itself is very comfortable. I spent some time lying on the bed and using the remote control to find the best position for me, the remote has a preset button so now I just get in bed press the button and the bed moves to the position required

Great purchase! We use 'Zero Gravity' mode (ZG) often, especially after I play sports and feel fatigued and achey. It feels amazing, like you are weightless and it's difficult not to drift off in that position which is meant to be the natural sleeping position. The massage function is quite good but I wouldn't say it's outstanding, although we haven't yet used it properly so it'd be unfair to review it negatively. All in all, a really good buy from Dreams with cover for £99.

Overall I think this bed frame has been a good purchase for me. I have been wanting to have an adjustable bed for a while and this has been a good choice in terms of the number of positions you can have to get completely comfortable. I am not fully convinced by the massage function yet. It also comes with height extenders for the legs which is a great option if you would prefer the bed to sit a little bit higher than standard.

The bed i sturdy and work well. I had one and has bought one more. Great product. It would be perfect if the bed proportions were better split (head, fixed mid region, legs and lower legs). The weakness of the bed is in the proportions. The medium fixed portion of the bed is too long, as a consequence the header start to go up in the thoracic region instead of the lumbar. The legs start to elevate in the middle of the legs.

A little wary because first time buying an adjustable bed but so pleased we committed and the Sleepmotion 400i plus the mattress chosen is very comfortable. Especially useful when using the bed in the daytime for reading, using a tablet etc. I was able to reconfigure the old bed frame around the new bed and it's moving platform so looks good too. Easy to find a comfortable position with the memory functions. Very pleased.

This bed is phenomenal. I can't imagine sleeping flat anymore. The simple ability to raise your top half up to watch TV, work in bed, breastfeed with such ease is a Godsend. I bought a lot of items in my recent house move and this bed is by far my very best purchase. I have already made converts - my parents, aunties and Grandmother are planning to purchase this bed too.

Great space saving large bed. We wanted a king-size bed, but had limited space. Only way forward was a frameless bed. This fits perfectly. I had compliments on it looking hotel quality. The feet height is amazing, I struggle to stand up in the morning and with the bed so high and only being 5ft3 it's perfect. You have options to choose from on the height of the bed upon delivery which is fantastic.

Easy to put together with simple instructions, I just managed myself but really needs another person to flip it over onto its feet, its really heavy! The bed is awesome, we went with the medium Hyde and Sleep mattress which is super snug. The only thing we didn't factor in was when the bed is raised up, your out of reaching distance of your bedside table (take your cuppa with you ;-)

The bed is fantastic no issues there but I asked for my bed to be disposed of and charged 30 to find they would only take the base. Had I have known this I would have asked the council to take away as they are cheaper and would have taken the mattress too. When I rang the Peterborough office to complain I was told "never mind!" and no email address to make a formal complaint.

After the first month of use, I have found a marked improvement in my sleeping. The range of positions during and throughout the night allow me have a more comfortable nights sleep than with my previous beds. For the first time in my life I now sleep on my back with my legs slightly raised, which I had not been able to do previously.

This is a little bit of heaven. I love a gadget and being able to move the bed rather than have to get out and rebuild my mountain of strange shaped pillows is wonderful. I sleep sitting as I have a bad hip but there are good days when I want to be more supine. Love it to bits. Took a very very long tome to arrive though.

In no time I was able to play around with the controls to find a comfortable position for watching TV while in bed. Now the position is saved in the remote's memory all I need to do is push M1 of the three memory buttons on the remote to return to the position. Wish I brought one of these when they first came out.

The bed frame is very sturdy. I have the extended legs so that I can store things underneath, which does make the bed quite high. I'm going to experiment with a valance to see if it ends up in a mess when I move the mattress about. It's not unsightly on its own, it just doesn't match anything about my room.

I bought this just before the official launch as there was only the 200i and 900i. sleep motion then brought out 2 new intermediate models so perfect for choice and getting the best value for the essential options you need rather than paying for features you are not going to use.

Well made with good quality components. In the first week the 'TV Setting' stopped working. I did the usual - turn off and on again. It now works. This has given me a lack of confidence, will I have to do it again? I reported this to Dreams CEO, no response.

Finding it different from my previous Dreams adjustable bed and not as comfortable as I expected but it's only been 2 weeks so I'm hopeful it will settle. Missing the added lamp plug and the underbed light as well as the light on the remote

We bought this bed due to my wife having a bad back and me having asthma. I can honestly say it has had a massive positive impact on our sleeping and helped with our medical problems. I would recommend this to anyone. So easy to use too.

This has been a great bed; easy to use, fits in the room well and I have been sleeping much better in it since it's arrival! I like the range of adjustability it has, as well as the very comfortable matress, and it's space saving design

The bed is very comfortable and does what I need it to do. It's very simple to use too. It's much easier to get out of bed these days, I just lift the head end a little and I can easily get out. Great purchase and would recommend.

Absolutely love this bed, so easy to use with the App. So comfortable. Easy to put together too. Probably would be more useful if it had electronic height adjustment too. 2 men that delivered were very helpful too.

This bed has made a good nights sleep possible again. I suffer from chronic health conditions and struggled for years to be comfortable enough to sleep in a bed. I can't recommend this bed enough.

Very good base. Adjust to several different positions using the remote control, very smooth operation. I haven't tried the foot or back massage yet, but the zero G sleep position is comfortable.

Excellent purchase - I love the bed and particularly the three "preset" buttons on the remote control. I also like the massage vibration although apart from the lowest setting, it is very noisy

Mama to the rescue
Good morning I have already purchased a dormeo mattress and I would love to have this bed. Would I be able to use them together and how does the mattress manage to stay in place and not fall over the bottom edge.
Answer: You would need to speak to Dormeo directly so they can confirm if their mattress would be compatible.There is a mattress retainer bar that is fitted onto the end of the base to keep the mattress in place. Please see the assembly instructions on the product page for a better understanding of this.

Good morning Is it possible to put 2 single Sleepmotion beds together to form 1 superking so that you can adjust the beds independently?
Answer: Unfortunately there is no way to connect the beds, but you could stand them next to each other. However they would be 10cm shorter than a super king size. They would also need to be controlled with the individual remotes they come with, you wouldn't be able to use one remote for both beds.

please can you explain the difference between back support (that the 400i has) to lumbar & back support (on the 800i) ?
Answer: The 400i has back and lumbar support, these are the same on the 800i, the only difference is that the 800i also has head support which is a small section at the top of the bed which can tilt to change the angle of your head when you sleep and can help open airways while you sleep.
