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.

Hypnos Owner Satisfaction

Customers of Hypnos mattresses are in for a treat, with more reviews than ever we’re been able to dissect and deep dive into what makes these mattresses great and the general consensus is that while a little bit pricier than alternatives, the quality and support all come together to offer a fantastic range of mattresses which perform extremely well and have received the Royal Warrant. People who own these mattresses report fantastic back support from the medium and firm tensions while the pocket springs contour to each and every part of your body and offer great quality at reasonable price points.

Hypnos Supportiveness

Hypnos mattresses are renowned for their supportiveness, offering a variety of different mattress tensions ranging from soft through to firm. The Hypnos lineup typically features pocket springs as a support layer which is thankfully one of the best bases you can get in mattresses. As a result, these mattresses are some of the best in the industry and with the wide range of tensions, there is something for everyone. Consider a medium tension mattress for back and side sleepers of most weight classes while a firmer might be more suitable for back sleepers or those with a heavier build.

Hypnos Durability

Hypnos mattresses have a huge benefit over many of the competition when it comes to durability. That’s because they have a very no-compromise approach to their range of mattresses, giving you the best in materials and not working to the same sort of budgets as other mattresses. Featuring numerous natural materials and handcrafted in the UK, all mattresses are guaranteed for 10 years which is market leading and exceeds the average life expectancy of a typical mattress from other manufacturers. Additionally many of the lineup are 2-sided, meaning you get the comfort layer on both sides of the mattress which gives you twice the surface area, increasing durability and ensuring even settlement over time.

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.

I waited approximately 6 weeks and several mattress turns before my review for my Hypnos Earth 01. I changed my original mattress from Bensons for this one, big upgrade wise. I wanted a firm mattress with a soft outer. I took the advice and swapped for the Hypnos 01 Firm instead of Extra firm. The mattress is super comfortable just dips a little when in it (I weigh 9.5 stone). I have never slept better so now I can justify the outlay! No getting used to it at all, I drop off so quickly and stay asleep all night. On reflection I would have ordered the Extra firm as this mattress is well padded with my theory being it might last longer but I know diddly squat about mattresses to be honest. Really impressed with Hypnos though, lovely quality. Onto Bensons; they were so helpful. On changing my mattress to communications generally just excellent. From customer services, the delivery coordinator and the delivery guys. It really blows your mind when you get really good service these days, they follow through on everything. My sister in law recommended them, she wouldn't use any other company and I see why! Highly recommend and many thanks to you all. A happy sleeper

Having conducted much research into getting a new mattress I'd decided that I did not want any which would be involved in the involvement with too much in the way of chemicals being used such as can be found in many foam mattresses. Also given the fact that people might readily shell out 2k on a two week holiday but then scrimp on spending the same amount on a mattress ( which they would potentially spend a third of their lifetime sleeping on ) I decided that if they're good enough for royalty then they're just about good enough for me. I plumped for the Hypnos Earth 2 ( even though it has hardly any reviews) and am very pleased with my purchase three weeks later. It offers decent support yet isn't too hard and my backache has subsided somewhat since and am sleeping better. So my verdict is to go for it and at least try oneafter all you only live once ( on Earth- get it ? )

We are delighted with our purchase of Hypnos zip and link mattresses from the Benson For Beds Poole branch. We'd visited a few local retailers but were very impressed with the service offered by the staff here. Our 'guide' Luca was particularly knowledgeable about the products we were interested in and helped immeasurably while we deliberated upon choice. The following day a first-class deal was enabled with the help of Store Manager Paul and after a shake of hands we left feeling very happy. A five week wait and with the mattresses now in-situ on our ottoman base, we absolutely would recommend this store. Thank you.

Normally I have to get used to a new mattress but not this one. I genuinely absolutely love this mattress, it is perfect for me. I do have a grumble though but this is not with the quality of the mattress - I was informed only at the point of delivery (on my drive) about the size of the distance between stairs and ceiling. If it is below a certain measurement then the 10 year warranty is void!! My house is a new build with standard measurements which falls less than 2cm below the necessary measurement to retain the warranty. This really annoyed me as I had to decide to send it back or sign away the warranty.

We are extremely happy with our new mattress. The knowledge of staff and assistance we received at the White City Manchester branch when we chose it was excellent. We have always had an extra firm mattress, however, as we have got older we decided it was time for a bit more comfort. So glad we chose this mattress, it is comfortable but gives the right amount of support. The pillow top makes it feel very cosy. It does have a slight smell, but it is not unpleasant and with regular airing of the mattress it is dissipating. We are definitely sleeping better. So happy with our purchase.

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.
