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.

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.

Sleepsoul Owner Satisfaction

Satisfaction looks to be fairly high with the SleepSoul range, although there are a few exceptions in the lower priced open coil quadrant where they do not perform quite as well as some customers have hoped. The mid and upper tier both perform well however, with pocket spring units shifting large volumes and considerable positive reviews.

Customer reviews are overall positive with people impressed about the price to performance ratio offered through this new bed in a box offering.

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

Durability is a concern that many customers have when it comes to the SleepSoul range and one that cannot be immediately addressed. See, there are no long-standing durability tests because there are no long-standing customers on account of the brand being so very new. As such we just don’t know just how well these mattresses will perform in the years to come.

To offset this concern, SleepSoul has developed a 5-10 year warranty (depending on model) to accompany the purchase of mattresses in the range. This warranty should go a considerable way to alleviating many of the concerns shared by the community and will help establish SleepSoul as a leader in the industry.

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.

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.

Easy to manoeuvre on delivery being vacuum packed and boxed. Ordered two mattresses for children moving from cot beds to single beds. Had them out of the packaging for about 6/7 hours before first use which seemed ample. Both kids slept well and said they were comfortable to sleep on. We lay on them after unpacking and they were very comfortable and stable. They feel like they offer the support from the traditional pocket sprung aspect but have the extra comfort with the thin memory foam top without being too thick to get that sinking feeling when youre on thicker foam. Based on experience so far would definitely recommend them for the price. We were hesitant as wanted good mattresses for our children so were originally thinking of going for one of the more major brands. So glad we didnt though, we went based on the amount of such good reviews and these have offered such good value

Based on the product description and reviews I was expecting a softer mattress than I got. It does have a softness as you sit or initially lie on the mattress, but it soon gives way to a more solid firmer feel, which while supportive isn't quite the sleep on clouds feeling I was expecting. It is a supportive and comfortable mattress and excellent value for money. I don't feel the springs under me as I sleep though you can feel them along the side edging, this mattress does not have reinforced edge foam along it, which I wasn't expecting anyway. When you're laying down the feeling is more medium to medium firm to my 12 stone body anyway. I've decided to keep it and I would recommend it overall. For the price paid I think you can do alot worse. Time will tell how it holds up.

5 Justin Cooper

I bought 2 of these for a 16 year old and a 19 year old and they love them, I normally only buy silent night but the reviews were great so I risked it. I thought there cheap enough to try, well the risk paid off. You won't find better for that price range. Infact you can probably spend double on a silent night and it will still be inferior. I've just ordered a third for my 5 year old his mattress doesn't really need changing but for that price I thought i'd upgrade the little one as well. I hope that sleepsoul keep doing a great job and making top quality affordable mattresses because they're great and i'll be picking a king size up for the wife and myself when ours needs replacing.

5 Steph

Absolutely brilliant mattress. I was really worried about not being able to test it due to ordering it online rather than in a store but was reassured by the trial period offered. I've struggled with neck and back problems for years since my memory foam developed a large dip and this mattress has fixed all of that. It manages to be firm enough to provide support but soft enough to feel cosy. It's the best one I've ever bought and highly recommended it to other super fussy people like myself!!! It is VERY HEAVY so you'll need help turning it at the 6month rotation mark, then again I weigh 120lb and managed to unroll it upside down (!!!) so you might be ok!

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.
