Otty

Otty is a British brand that started in 2017 and has grown quickly into one of the most recognised hybrid mattress names on the UK market. The company is based in Leeds and sells direct to the customer, cutting out the middle man in the traditional bed retail chain and passing the savings on in the form of long trial periods and sensible prices.

Their hybrid lineup pairs cooling gel infused memory foam with individually encased pocket springs, and it is the hybrid build that Otty is best known for. Every mattress ships vacuum packed in a box, and buyers get a 100 night home trial along with a 10 year guarantee.

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.

Otty Owner Satisfaction

Otty mattresses sit at around 4.7 out of 5 across the review sites we track, which is close to the top of the hybrid category in the UK. Most of the praise focuses on two things: the genuinely cool feel, which comes from the breathable cover and the open spring layer, and the edge support, which is noticeably firmer than most foam rivals.

Couples tend to rate Otty higher than single sleepers, because the pocket springs absorb movement well and the firm edges mean nobody rolls towards the middle. The mattress is on the firmer side of medium, so side sleepers who want a very soft feel sometimes find it a little too supportive, but for most average weight sleepers the firmness works out just right.

Otty Supportiveness

The Otty Original Hybrid uses a top layer of cooling gel memory foam over a reflex foam transition layer and a core of pocket springs. Each spring moves independently, which is why the mattress copes well with two people of different weights sleeping side by side. The foam layers add enough pressure relief for the shoulders and hips, and the spring core keeps the lower back properly supported without letting anyone sink into a hammock shape.

For heavier sleepers over about 16 stone, Otty also makes the Pure Hybrid Plus, which has a reinforced spring unit and thicker comfort layers to stop the mattress bottoming out. In both models, the support level is one of the things owners consistently pick out as a strong point.

Otty Durability

Otty uses a high gauge spring unit and good quality foams above it, which is the right recipe for a mattress that holds its shape over the long run. The cover is removable and washable, which is unusual at this level of the market and helps the mattress stay fresh over the years.

Long term owners we have spoken to report very little sagging at the three and four year mark, and the 10 year guarantee gives a clear signal of how much life the brand expects out of its own product. Given the materials and the build, Otty mattresses are well positioned to last the seven to ten years that most buyers are looking for.

    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.

    The plush comfort yet firm support is really impressive. It must be due to the mixed layers of wool, silk, and cashmere along with the firm pocket-spring core. Truly, it is a good balance.

    5 Aliceee

    Really comfortable and noticeably cooler than my last mattress, definite improvement in my sleep quality. Unboxing was easy and it expanded to full size quickly.

    4 Verified Buyer

    Felt a marked improvement in sleep quality due to the firm yet comfy feel of this mattress. Especially appreciated how it stayed cool throughout warmer nights.

    5 Sean A

    Really good product. It's made a difference to my sleep, no more waking up with a sore back. Comfortable yet very supportive. It's great value for money.

    Enjoying the blend of traditional craftsmanship and innovative design. The mattress is firm yet gently cushioning and I've noticed a much cooler sleep.

    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.

    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.
