Tests & Verdict

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and 12+ years of industry insight.

Well loved by customers and featuring 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.

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.

Why our sleep experts loved it

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 400i headboard is available separately for those who want to complete the look.

Based on the customer reviews provided, it seems that the Sleepmotion 400i Adjustable Platform Bed Frame is largely well-liked by its users. Customers have praised the bed's 3 adjustable areas, Zero Gravity technology, and massage units, as well as its sturdy construction and compatibility with a separately-sold 400i headboard. Many reviewers have also reported improvements in their sleep quality and a reduction in the severity of their snoring after using the bed.

It's worth noting that some customers have mentioned that the bed frame can be a little expensive, but overall the value for money seems to be good based on the features and benefits offered. No specific dislikes were mentioned in the customer reviews we looked at.

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.

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 dont 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.

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

Questions and Answers About The Sleepmotion 400i Adjustable Platform Bed Frame

Prospective customers had the following questions about the product

Dsmithbristol
I notice you said that the bed should not be entered when it is raised. I need a bed that can sit me nearly upright as I have a spinal cord injury. I would then transfer off the bed. I have no core muscles so can't sit up on my own.

Answer: I am sorry to hear this. Unfortunatley this bed is not designed to bear weight at a single point which is why we advise not to enter or exit the bed while in a raised position. The bed is intended for a distributed weight, so there is no excessive pressure on the mechanisms. I apologise I cannot assist any further here.Many thanks

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.

Hi cannot seem to find an energy rating anywhere for the 400i superking

Answer: Sorry for the delayed response on this. We have been looking into this and as the bed frame falls out of scope for the EPREL (European Product Registry for Energy Labelling) we have not tested this for an energy rating. We apologise we are unable to provide further information on this. Thanks, Dreams

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.

Can you add bed rails to this bed

Answer: If you mean side rails we will be selling this bed as a drop in with a bedframe in the near future.If you mean patient helper rails, then unfortunately we cannot confirm this as we have not tested this with the bed.

Are your sleep motion i400 bed frames compatible for a headboard? And if the frame only fits your mattresses shouldnt that be a fixed price for a complete set option with discounts being given on whole unit prices or discounted assembly of the unit.

Answer: We are currently designing a headboard for the 400i frame, we aim for this to be available in March 2021.I am sorry but unfortunately we do not have a discount available to purchase the frame with other items.

The 200i has a metal anti slip bar at the end of the bed, the pictures for the 400i does not show this. Is this optional for this model or not a possibility

Answer: Apologies for this, as you can see in the reviews section from a customers photo and within the assembly instructions, the 400i does have a metal anti slip bar. Thanks, Dreams.
