Sleepeezee

Sleepeezee has been making mattresses in the UK since 1924, and is one of only two mattress brands in the country to hold a Royal Warrant for supply to the Royal Household. The company is based in Rochester, Kent, and still manufactures its beds in the UK today, which is something that has become increasingly rare in a market now dominated by imported bed in a box products.

The range is broad and covers pocket sprung, hybrid and memory foam models, with the Hotel Collection and the Cooler collections sitting at the more popular end of the lineup. Sleepeezee also licenses a Jeff Banks range that brings a designer name to the traditional pocket sprung mattress format.

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.

Sleepeezee Owner Satisfaction

Sleepeezee mattresses score around 4.5 out of 5 across the main review platforms, which is a solid result for a brand that is mainly sold through third party retailers rather than direct to the consumer. Buyers who want a traditional, tufted pocket sprung mattress with natural fillings tend to be the happiest with what Sleepeezee delivers, because that is where the brand's strengths lie.

The Hotel Collection is particularly well received, as it replicates the kind of firm, cool feel you get in a good hotel bed. The main complaint we see, and it is fair to raise it, is that because most Sleepeezee mattresses are sold through shops rather than online, the trial period varies by retailer and is usually shorter than what a bed in a box brand would offer.

Sleepeezee Supportiveness

Sleepeezee builds its mattresses around pocket spring units in most of the range, with counts running from about 1,000 in the entry level models up to 2,800 in the higher end Backcare and Cooler ranges. The higher spring counts are not just a marketing number; they genuinely improve how closely the mattress contours to the body, which matters more for lighter sleepers who need the springs to react to less pressure.

Above the springs, Sleepeezee uses natural fillings such as wool and silk on the better models, which adds a layer of give without softening the core support. The firmness options run from soft through to extra firm, so most buyers will find a version that suits their preferred feel.

Sleepeezee Durability

As a UK manufacturer with a hundred year trading history, Sleepeezee has the kind of build quality that is hard to find in newer direct to consumer brands. The mattresses are hand tufted on the better models, which stops the fillings from shifting over time and is the main reason traditional mattresses last longer than their budget counterparts.

The Royal Warrant is not handed out to brands whose products fall apart, and the consumer mattresses use the same construction methods as the ones Sleepeezee supplies to the Royal Household. Owners regularly report getting eight to ten years of good service out of a Sleepeezee, and the materials used today suggest that should remain achievable for anyone buying now.

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 would like to say that the two gentlemen that delivered and assembled my bed was amazing! James and the driver ( my apologies for not remembering one of the other gentlemen’s name, I have a bunch of medical issues that causes slight memory loss and other issues) They were very polite, friendly and very helpful / informative, they even demonstrated how to open and close my divan ottoman bed as it’s been a while since I’ve had a demonstration at the dreams store. They even got the job done in less than 30 minutes and they made sure to clear up everything before they left to make sure that my safety was first, as I have mobility issues. They even phoned me before to inform me about what time they will be here and to go over any important information. They wore shoes covers to keep the dirt out they even changed them every time they went out and they were in their uniforms which were very clean and smart, again I have medical issues which can cause flare ups and they did everything to prevent any dirt coming into the house to put my medical issues first. He also made sure I was happy where the placement of the bed was and how it looked and I was very happy with my purchase. I can’t think of any more words to give about how pleased and happy I am with how they handle it and how pleasant they both were, alls I can say is that I’ll definitely recommend them to anyone as they are amazing. With that being said I believe they both deserve a pay rise and full on recognition for their outstanding service, because they respected my medical issues and gone out of their way to adapt to my needs and I’ve never had any other delivery team do that before and that meant a lot to me. Thank you very much both of you ?? As for the bed itself, it’s very lovely and it was my dream bed all along. The storage part Is very easy to open especially with my medical needs and I find that hard with other bed brands that don’t cater to disabled people, and it’s very spacious for bedding or extra storage essentials. The mattress was amazing and very comfortable, I had to get a medium firm mattress as it was recommended from my doctor for my fibromyalgia and other issues and it’s perfect. Finally the colour of the bed was exactly like the picture and it matched perfectly with my room colour scheme. So I’ll definitely recommend this company and I’ll definitely be purchasing from them again.

I was just passing Dreams and having had a mattress for nearly 9 years didn't realise that it should be replaced having seen the advertising from the doorway. Rayanne immediately approached me with a smile and warm welcome to find out what I needed. I didn't really know and assuring me with her knowledge she explained how the process worked with regards to finding a new mattress to specifically suit my needs without any pressure, jargon or hard sales push. This was a fresh revelation. It was like she was a professional expert here to advise and guide. She showed me the mattress test that would give me some ideas to what would suit my body, preferred sleeping position and budget. All this was done whilst reassuring me of their Covid arrangements to ensure safety and make me feel safe and reassured. After using the machine for 3 minutes she went through the recommended mattresses. She was not rushed, but to the point, politely and in a friendly manner. She made me feel relaxed and not pressured into buying but with such professionalism, knowledge and guidance I knew that I now needed a new mattress. I tried several (with my own pillowcase cover that was sprayed) and she allowed me to go back and try them again to make sure I was happy with the purchase. She reiterated that even after the mattress was delivered I still had time to change my mind. Such a great experience. Relaxed, professional and knowledgeable. This is how all sales staff should be and what a great employee Rayanne is! More like Rayanne please!! I be back in eight years time to buy again!! PS Since buying the mattress (3 weeks ago) I have had the best sleep ever. The mattress was actually half the cost of the previous one I bought (from a reputable high street store)! I'm coming back to Dreams in future!

A spring mattress that gives you a spring in your step!I could not speak more highly of this excellent organisation and the professionalism, alacrity and everything else that goes into choosing a new mattress. And at christmas/new year period too, when one would imagine they'd be rushed off their feet, let alone on their backs. Replacing your old mattress can be a rather daunting task, you really don't want to send anything back, let's face it. Do it right the first time or not at all. Especially if you are looking for great spinal support when you have back injuries and arthritis to match the hunchback of notre dame. Because while you don't want to wait forever for that 'dream' sleep, you don't want to rush in, be taken in by the hype that is 'out there' over "do I go no spring, extra spring, or memory foam?" I was going to go elsewhere before I laid my eyes on mattressnextday - and yes, I was taken in by the 'get your mattress in 2 days,' and why not too? This waiting for weeks while you suffer? This is no longer the 20th century chaps. So, I chose, and I could not have made a better choice. Dreamy, lovely, firm and not a smell from foam that you have to spend two days airing out in either nostril. I went for the sleepeezee cashmere royale pocket mattress - yes, why not, king size (5' x 6'6")569.95others were around this price, so why not. There was no courier fee but a charge for carrying it to my room of choice - a small price to pay at 14.95. I could not be happier. My back, shoulders, knees and ankles could not say thank you enough. The name 'sleepeezee' says it all, and mattressnextday was pretty much on the ball.

My fiancé and I had recently moved into our apartment. We were very very keen to spoil ourselves on a new mattress as we are very much under the impression that you spend a third of your life sleeping. We decided to visit your Wandsworth bridge road branch in which we were welcomed in a friendly and warm manner by Riccardo. Firstly, he offered us something to drink in which we then had a chat around what we were looking for. He then advised us to give the sleep match tool a go so we could pin point the exact mattress to our specific needs. Once the process was completed he then showed us all the mattresses that the the tool advised on. Very patiently he carried around two pillows as myself and my fiancé tried out all the mattresses. Having a budget in mind from the start it was due the expertise of Riccardo that we decided to go over our budget and really spoil ourselves on a top end mattress, which we purchased. With regards to the delivery, unfortunately our order was placed on the 22nd of March, a few days before the lockdown. This ultimately had a massive impact on our delivery day which was meant to be on the 15th of April but due to COVID-19 we only managed to receive our order on the 8th of June. All I can say was that Dreams did keep us up to date and we were very much aware of the issues. We are very happy with our new mattress and our sleep has never been better, well worth the wait. Thanks so much! Regards Andy

Lovely welcome at the Mansfield store. Tried the bed that takes your weight, hight and slept position's (very clever) the bed moved under us and worked out everything. We were then given a list of mattresses matching our needs, we picked this mattress because it felt amazing. Nice topper, firm like we wanted for our bad backs but comfortable. It was more than we wanted to pay but it was a case of ' you get what you pay for '. We came to Dreams 10 years ago brought a fantastic mattress, but our lovely dog destroyed it after a year so we brought cheap but recommended mattresses. This messed our backs up so be brought another different cheap highly recommended a few years later, then another. So after wasting our money on cheaper mattresses that claim bold statements we came back to dreams. This mattress is top quality from inside to outside. You need to go to the shop to find your fit for your needs but if this is the one you like I can honestly say it's fantastic and my body can sleep in the proper position and I wake up feeling refreshed. See you next time, thank you.

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.
