Head to head

Both ranges are sprung throughout, so the difference is in the comfort layers on top and in price. SleepSoul runs from soft-medium to firm, and Mlily runs from medium to firm. SleepSoul is clearly the cheaper way in; Mlily's range starts well above it. At the top end Mlily goes further still. SleepSoul's owner score rests on far more reviews (2,855 against 407), so treat Mlily's number as the less settled of the two.

SleepSoul

SleepSoul is one of the newest manufacturers to make a splash in the last few years, entering the arena at the start of the first lockdown and rapidly expanding through its use of existing supply chains provided by its parent company, Birlea. Since inception SleepSoul has rapidly gained a strong market position in the bed in the box space, competing directly with other popular manufacturers like Eve, Simba and Nectar.

SleepSoul are not sold directly and are instead sold through a host of retailers up and down the country in both online and offline capacity where the price of these mid-tier priced products tend to get carved up down to the lowest pound as everyone reaches to capture the sale.

Mlily

Mlily is a Chinese mattress manufacturer founded in 2003 that entered the UK market in 2016 alongside a partnership deal with Manchester United football club. The brand builds hybrid mattresses using memory foam, reflex foam and micro-pocketed coils, with the distinctive construction detail being high-density foam wrapping around the micro-coils to produce a less springy, more stable sleeping surface than conventional pocket spring designs.

What separates Mlily from most bed-in-a-box rivals is the combination of hybrid construction with international manufacturing scale. The Chinese production base keeps costs competitive, and the engineering approach of wrapping micro-coils in foam delivers a feel that is noticeably different from either pure foam or traditional pocket spring mattresses.

SleepSoul owner satisfaction

Owners are mostly happy with the SleepSoul range, and the praise is much the same across it: comfort, value and a box that is easy to unpack. One Bliss 800 owner called it “Good quality and excellent for the price”. Another found it “very easy to manage, open and soon plumped up”.

Firmness is the recurring complaint, and it runs both ways on the same model: one Bliss 800 owner wrote that it was “not medium as advertised. It's soft.” Another found the same mattress “Far more firm than the description suggests”. A few owners find them warm at night. The other complaint that keeps coming up is edge support, mostly on the Comfort 800 and Heaven 1000, and a few owners across the range say they can feel the springs. One Comfort 800 owner wrote that “the unsupported edges are annoying”.

SleepSoul supportiveness

Supportiveness is at the forefront of SleepSoul design, with pocket spring support structure taking centre position in the lineup and offering a great variety of tensions ranging from medium to firm in their more popular offerings. The open coil variants perform less well however, do feature at a price point making them a great option for those on a budget,

The support layer in much of the range is able to be compacted and rolled, giving you a tighter package come delivery that saves on logistical and delivery costs that can be passed on to you.

SleepSoul durability

Owner reviews of the range go back years, and those that mention wear are split. One owner bought a second SleepSoul about five years after the first and said the original was “STILL as good and cosy as new”. A small number report a dip or sag forming within the first few months.

To offset this concern, SleepSoul has developed a 10 year warranty to accompany the purchase of mattresses in the range. This warranty should go a considerable way to alleviating the worry over sagging and will help establish SleepSoul as a leader in the industry.

Mlily owner satisfaction

Owners rate Mlily well on the whole, and comfort and value for money are what they praise most. "Very comfortable and good quality ensuring a good nights sleep", one wrote, and another called theirs "Really good value compared to major stores". Some are repeat buyers: "We have always used the MLily brand and it's the best by far". Not everyone is happy. Firmness is the main complaint, with some owners finding their mattress firmer than its label ("This mattress was advertised as medium in firmness but is actually firm") and others softer than they expected ("Nowhere near as firm as I was expecting"). Back pain eased for many owners ("Since sleeping on this mattress I've no back ache") but not for all of them, and one was "still suffering from bad back". Some find the memory foam warm, and plenty wish a mattress this heavy had handles.

The 5-year guarantee across most of the range shows genuine manufacturer confidence. The Bamboo+ models have a knitted bamboo cover, which one owner called "very nicely designed and soft to the touch".

Mlily supportiveness

The hybrid construction pairs memory foam comfort layers with micro-pocketed coils wrapped in high-density foam. The wrapping changes how the springs behave, reducing the bounce and motion transfer that conventional pocket springs produce. The result is a supportive but stable surface that suits side sleepers and back sleepers well. The Premier 2000 is the sweet spot for most buyers, with the Hybrid Ice 7000 handling hot sleepers who want cooling gel alongside the hybrid support.

The deep memory foam layers mean the range is less suited to stomach sleepers and restless sleepers who change position frequently during the night. The slower foam response can feel restrictive for sleepers who need to move easily on the mattress surface.

Mlily durability

Most Mlily mattresses use a hybrid construction that combines foam comfort layers with micro-coil structural support, which is the format we expect to deliver better long-term durability than all-foam alternatives at similar pricing. The micro-coil and high-density foam wrapping construction adds structural integrity that pure foam builds cannot match. Owner reviews say little about wear so far. One says theirs "Feels like it's going to last us a good few years", while another exchanged a firm model after the memory foam "created a permanent indent".

The 5-year guarantee is reasonable for the price tier. Chinese manufacturing keeps costs down, and owners often remark on the build: "It's very well made and extremely good value for money", one wrote.

This is a really comfortable, good quality mattress. When it arrived (in an amazingly small box), the mattress was well wrapped up in plastic and there was a little tool to slice the plastic open without slicing the mattress, plus instructions for the mattress. It was simple and straightforward and the mattress was ready to sleep on in just an hour or so. There was no obvious chemical smell, just a slight whiff if I put my nose right on it as soon as it came out of the wrapping. I haven't been bothered by any smell when sleeping on it. I bought it as an urgent need because the old one was giving me back pain. After two nights on this mattress, the pain was gone and i've had a couple of weeks of very comfortable nights with much better sleep so far. The only thing i'm not so pleased with is the edges squish down when you sit on them. I guess they have to in order to fit inside the small box but I prefer the edge of a mattress to keep its shape when I sit on it. It's not a major problem as I sleep alone but if I shared it and had to sleep near the edge, i'd feel as if I was going to roll out of bed. I'd want a king size if I was to share it. I will also get a mattress topper just to increase the comfort factor even more (and to fulfil the conditions of the guarantee). Overall, I am very happy with this mattress, it's great to feel comfortable and well supported. With the discount, it's amazing quality for the price. So glad I bought it; my back thanks me every morning.

Good Points: It's the first new mattress I have had in years and its quite a difference but theres lots I like about the change: - The mattress is very supportive of my body, I'm 5'11 and weigh nearly 100kg's, support matters! - It feels stable and doesn't make me roll to any low spots - The mattress is far lighter than I anticipated so rotation by myself is really easy, especially with the handles - It keeps me warmer which during the late heat was a bit of an issue but I think I'll appreciate it during the winter - It arrived rolled and it was easy to remove and set up in no time Improvement Points: There are a couple of things but these are very minor, and they are just my views: - The handles, despite the low overall mattress weight dont feel very sturdy and I worry I'll rip them clean off - The measurements indicate the mattress depth, and was made very clear on the website, but depite my measurements it was still a shock to see such a deep mattress having been used to very thin one for years - I think I remember seeing it mentioned as being on the firmer side of things but compared to my previous mattress this is much softer (not necessarily a bad thing, just didnt expect it is all) Thats it really. As you can see the negatives for me are very minor and I would overall highly recommend the product.

The product itself is as expected, it was delivered vacuum packed in a box as tall as the mattress is wide and rolled up, so it doesn't take up too much space and is just small enough for the average male to handle. It is of cause a bit on the heavy side so probably be a good idea to get help if moving up stairs but is easy enough to slide up the stairs on its side. The box contains the mattress along with a handy safety knife to open the vacuum sealed bag and some documents. After removing the mattress from the box take care with the unrolling as it is a bit weighty and king of suddenly springs/flops the last 2 or 3 foot so have no breakables near the end if unrolling on the bead frame. When cutting the plastic try not to cut a large hole, doing this will allow the air to gradually enter the mattress and the mattress will safely spring back to it intended shape, then you can remove the plastic with the provided safety knife. The mattress boasts a 1000 pocket springs topped with memory foam so no need for a mattress topper as there's plenty of padding on top of the springs. I found the medium firmness of the mattress to be just right for me and after having the mattress for a month now I can confirm that I sleep better. The price was very competitive the quality it right for the price but the delivery let down experience a bit, the guy was unbelievably miserable didn't say a word to me, didn't smile (giving off couldn't care any less vibes) attitude was disgusting.

Improvement Points: I ordered the 120cm wide 'small double' mattress. Once unwrapped, it was clearly far too wide and would not fit on my bed frame, being around 125 cm wide. I know that foam mattresses take a while to regain their proper shape, however this has not been as quick as anticipated. As a the spare bed mattress, it has slowly change shape, and after about 4 weeks of resting and not being slept on, it is now about 122cm wide. It just about fits onto the frame.

Good Points: In the first year or so resonably comfortable but then it goes wrong... Improvement Points: After about 2 years the mattress has developed 2 distinct dips, about 3cm deep (after ~4 hours after getting about of bed. They are worse first thing) so at night you keep rolling back into them. I'm told : 'Over a period of time the body will create a natural impression on the mattress. This is known as settlement and is perfectly normal.' I dont beleive a dip that is deep enough to affect your sleeping position is normal and i didn't have this in a previous memory foam mattress. We only changed as we went up in bed size. So after 2 years use of a mattress that has a 10 year warranty I am having to buy a new one as this is unbearable to sleep on. Spend a bit more and get something better with reviews after a few years, not a few days.

Good Points: So comfortably supportive everywhere that I have found it more comfortable without a pillow than any other bed I have had with a pillow. On my old mattress I was spending half the night in so much pain that I couldn't sleep, or waking in the morning hardly able to move and in pain. It's doing me a lot of good sleeping so much better. The way it's rolled into the packaging makes it easy to get through doorways and around corners into the room. The packaging itself is so good that I am intending to reuse it in some way rather than just throw it out. It comes with an additional envelope-style, good quality mattress protector. I can't say about longevity as I have only had it a few weeks. Improvement Points: I absolutely can't fault it. I am incredibly happy that I chose this one after lots of research and unable to shop in person because of lockdown.

After several weeks of use, I can confidently say this mattress has been a good investment, though not without a few issues. When it first arrived, it felt quite firm, almost uncomfortably so. But after about a month, it softened up nicely and now offers excellent support without being too rigid. I wake up without any aches or pains, which is a huge relief. Movement isolation is impressive, there’s no bounce or disturbance when shifting positions, making it ideal for light sleepers. However, there are a few practical drawbacks. The mattress is very deep, which makes finding fitted sheets a bit of a challenge. It also lacks handles, so lifting or rotating it is awkward and heavy work. It's worth noting, if you're using slatted bed base, the slats need to be closely spaced, otherwise, you risk voiding the warranty. Overall, it’s a great choice for comfort and support, but be prepared for a bit of a workout when it comes to changing sheets.

2 Sierra

Good Points: It's pleasant to look at and the quality of material is great. it feels fluffy and soft when you lie down on it, if that's what you're after then this ones for you. Improvement Points: I wouldn't say its suitable for back sleepers as it's too soft and it just feels like you're sinking.

We had a king size Hybrid Gel 3000 Mattress mid December 25. Over Christmas I’ve had hip pain so bad I can barely walk and had to take pain killers to ease it. I thought I had something seriously wrong with my hip so slept in the spare bed last night and woke up pain free! My husband had said he’s also been getting hip pain - not as bad as mine, but we’ve concluded we messed up buying this! We laid for some time in the show room at Furniture Village on it and thought it was comfortable, but the reality of overnight is terrible. I’ve read other reviews mentioning hip pain since and it seems a common theme. I would not recommend this mattress.
