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.

Coolflex

Coolflex is a value hybrid mattress range sold exclusively through MattressNextDay. The brand has grown from a single rolled mattress into a catalogue covering multiple construction types with a specific focus on cooling technology at accessible pricing. The range includes the Essentials Pocket Memory Hybrid, Premium Memory Hybrid, Hybrid Ice, Hybrid Chill and Lux Ortho Pocket, each targeting a different buyer profile.

What makes Coolflex worth looking at is the combination of proper pocket spring hybrid construction with cooling-focused materials at prices that undercut the major direct-to-consumer brands. For hot sleepers shopping on a budget, Coolflex is one of the first alternatives to consider.

Mlily Owner Satisfaction

Mlily carries a strong Trustpilot score and the brand has accumulated consistently positive reviews from UK buyers since entering the market in 2016. The Manchester United partnership raised the profile considerably, but the product quality is what has kept the positive sentiment growing beyond the initial marketing push. Long-term owners regularly report back that the products have held up well over time, which is encouraging for a relatively newer brand in the UK.

The 5-year guarantee across most of the range shows genuine manufacturer confidence. The bamboo fibre covers on some models are a regular highlight in owner comments for offering a different feel from the standard polyester knit that most bed-in-a-box rivals use.

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

Mlily uses 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. Long-term owner reviews reporting good performance over several years support this expectation.

The 5-year guarantee is reasonable for the price tier. Chinese manufacturing keeps costs down without evident quality compromise based on the review data we have tracked. The bamboo fibre covers hold up well over time and resist the pilling that affects cheaper polyester alternatives.

Coolflex Owner Satisfaction

Coolflex reviews are consistently strong on two specific points: the cooling performance is real rather than marketing decoration, and the value for money at this price tier is hard to beat from the mainstream alternatives. MattressNextDay handles delivery and returns reliably, which gives the buying experience a stable foundation that standalone budget brands often lack.

Hot sleepers are the buyer profile most likely to rate Coolflex highest, because the cooling technology in the Hybrid Ice and Hybrid Chill models delivers a measurable difference from standard foam alternatives. The main complaint pattern we see relates to edge support on the entry-tier models, which improves as you step up through the range.

Coolflex Supportiveness

The pocket spring cores across the Coolflex hybrid range provide genuine structural support that pure foam alternatives at similar prices typically lack. The Premium Memory Hybrid is the sweet spot for most buyers, with a spring count and foam layer depth that handles average weight sleepers across back and side positions comfortably. The Lux Ortho Pocket handles the firmer end for stomach sleepers and back pain sufferers.

The Hybrid Ice and Hybrid Chill add cooling layers on top of the pocket spring base and are the models to look at specifically for hot sleepers who want temperature regulation alongside the hybrid support structure.

Coolflex Durability

The pocket spring and foam hybrid construction that Coolflex uses across the range is the build type we generally expect to last longest at this price tier. Pocket springs provide structural longevity that all-foam alternatives cannot match, and the foam layers above use reasonable densities for the price point. MattressNextDay backing gives the brand a retail infrastructure that supports warranty claims.

As a newer brand, the long-term durability data is limited compared with heritage manufacturers like Silentnight or Sealy, but the construction approach is sound and the early-year review data is consistent with what you would expect from a well-made hybrid at this price.

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.

5 Verified Buyer

Feels good, comfortable and supportive, also thicker in size so happy with the height. I chose medium as opposed to orthopaedic and it??s a lot firmer than I thought so again happy as worried it might be too soft. Feels good quality as well as opposed to some which you know is tatty and the price was within my budget so overall happy.

5 Verified Buyer

My new Mlilly mattress is lovely. Very well made. It??s deeper than usual but this I expected from the description on the website. Very impressed by the support it gives. Not hard like an ortho mattress. Comfy from day one. Comes vacuum packed. Easy to install .

4 Michael Y.

Overall, this mattress offers a comfortable and cool night's sleep. It offers exceptional support for back and stomach sleepers, making it a top pick for those seeking firm support. However, softer it may not be ideal for side sleepers who need more cushioning.

5 Verified Buyer

Great quality, well made and so so comfortable. It is firm, which is perfect for me as I wanted the additional support, the memory foam though still let's you sink in. I'm very happy and I'm sure other customers will be too.

Very glad I didn't spend 900 on a mattress (as I was going to!), As this one is absolutely perfect and didn't break the bank (hurray!) Its soft on top, but firm and supportive... My partner and I do not roll into each other in the night as pre my previous mattress. We both sleep really soundly on this mattress which suprises me as he actually prefers really really firm memory firm mattresses that feel like concrete!! Doesnt give me back pains like my previous mattress, wake up refreshed. Something I was worried about for the low price tag! The edges are not reinforced so do sag if you sit on the edge of the bed - but its fine when you are asleep//roll onto the edge - ie, you dont end up falling off as with some mattress that are not reinforced!. It does get a bit hot with the memory foam, but after putting a bottom sheet on, it isnt as bad as it was on the first couple of nights.

4 Jillian Knight

Very good quality mattress! great support throughout and good degree of comfort. Mattress came rolled up so needed approx 24 hours to properly settle and for all the creases to disappear before I could use this. This time for the mattress to fully open was stated in the delivery note so I was not concerned about the wait. The only issue I noticed was the mattress is fairly heavy to move due to the number of springs inside, and there are no carrying handles on the sides that would have helped to assist with moving and positioning the mattress. Otherwise I am very happy with this product.

5 Eileen Smith

When I ordered 'next day delivery', I was sceptical. I need not have been. I received an email advising a next day delivery slot of 9.40 - 11.40 and the mattress was delivered at 11.15. The delivery guys were lovely carried it up to the bedroom. It was a great service. I only wish you did next day delivery black 5 drawer chest of drawers, as I have been badly let down by littlewoods and they had up to 15 days to deliver. Let me down badly and so I cancelled. I would recommend your company to friends and family. Thank you.

4 Nik Pringle

You need to ensure you have the mattress the right way up - indifferent nights sleep until I spotted it was upside down! getting used to it after a couple of nights, the edges of the bed are not as firm as our previous sprung one making it slightly uncomfortable to sit on the edge. There is also a tendency to roll together into the middle - hence 4 * as opposed to the full 5. I tend to find memory foam mattresses sleep "hotter" than normal ones - fine at the moment but may be a bit warm if we get a good summer.

5 Dawn

I was actually surprised with the quality and comfort of this mattress considering its very reasonable price. It was delivered rolled in several layers of polythene, which was necessary to contain it. It is a lovely deep mattress and so comfortable. I would recommend it to anyone, and am positive it has to be as good as any mattress considerably more expensive. Id been prone to back and hip aching problems on a mattress that wasnt right, this mattress solved that after first night.
