Slumberland

Slumberland is one of the oldest and most prestigious mattress manufacturers in the UK having first been established in 1919 in Cambridgeshire. To this day, Slumberland remains one of the largest mattress manufacturers, offering an impressive range of products in pocket spring support layers accompanied by numerous upper comfort layers, primarily of foam and latex.

When it comes to price point, Slumberland aims to capture the mid-range price tier while still offering upper range quality. This is evident in the pocket spring support layers offered across the lineup, a support that tops the charts in terms of body contouring and pressure relief.

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.

Slumberland Owner Satisfaction

Slumberland mattresses are well reviewed, expected given the brands huge selling power. When it comes to customer feedback, reviews are positive with thousands of reviews and happy customers. People particularly enjoyed the luxurious qualities offered from such a reasonably priced mattress with those customers believing they get very good value for money. Other positives come in the form of the support layer, offering full body contouring and pressure relieving qualities that offer a degree of orthopedic comfort that protects and helps against back pain.

Slumberland Supportiveness

When it comes to supportiveness, Slumberland deals almost exclusively with pocket spring base layers. I bring up pocket springs a lot because they are the true mark of a good quality support structure, they generally perform better in tests than open coil traditional springs and reflex foam. Pocket springs offer, on average, better support and better durability, lasting longer than competitors. Slumberland has core parts of their lineup dedicated to orthopedic support which will prove ideal for those looking for additional back and neck support. In terms of firmness, we see a variety of different tensions that will ensure there is something for everyone in the lineup. Recommendations typically see those with back or neck pain navigate toward firmer mattresses, accompanied by back sleepers and heavier weighted people. For those who sleep on their side or are of lower to average weight should perhaps consider a medium tension mattress. With support, it’s all relative and subjective to each person, so consider each mattress on its own individual merit before purchase.

Slumberland Durability

When it comes to durability, Slumberland makes some impressive strides with their lineup. Thanks to the pocket spring support layer you get a better base layer acting as a foundation for everything that sits above. What separates Slumberland from many other manufacturers is that most of the lineup features a 5-10 year guarantee. The guarantee is a testament to the manufacturer's belief in the product they are selling and how long it will typically last. Lots of the industry relies on a 1 year guarantee and helps demonstrate the level of quality offered within Slumberland mattresses. Combine this with the double sided nature of much of the range and you actually get twice the surface area of many competitors, further expanding on longevity and durability.

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.

Before purchasing this Benson's mattress (bensonsforbeds.co.uk), I discovered that the firmness of a mattress should be determined by a person's weight and sleeping position. There are many guides on the internet about this, such as sleepfoundation/best-mattress/mattress-firmness I am approx. 168 lbs in weight and a side sleeper, so I was very confident a good quality mattress which was medium firmness would be the best firmness for me. I am not disappointed with the Slumberland Natural Solutions 2000 medium firmness mattress. It is very comfortable although it feels much harder than my old mattress which was 17 years old and completely worn out. I chose the Natural Solutions 2000 mattress as it has natural fillings which are more breathable than foam layer mattresses. These natural fillings allow body heat to dissipate more efficiently than foam layered mattresses. This was very important to me as I live in a very well insulated building in a 1st floor flat, which also receives a lot of direct sunlight through the windows throughout the day and I tend to be a slightly 'hot' sleeper. I have not felt too warm in bed during August 2023 with my new Naturals mattress. The Slumberland Natural Solutions 2000 is also very good value for money when compared with other similar mattresses on the internet. The outer material feels high quality and so do the pocket springs when lying on them. It has 2000 pocket springs which helps isolate any movement a sleeping partner might make which helps to aid a good night's sleep, especially if someone sleeps with a 'restless' sleeper. Kyle was the friendly and helpful salesperson who I saw at Benson's showroom in Yeovil. I recommend the Slumberland Natural Solutions 2000 Medium Firmness mattress and Benson's showroom in Yeovil :)

Albeit expensive, what an absolutely fantastic mattress. We tried a few in the store (Llandudno) and were given loads of different tips, advice, and guidance, but this one really stood it for us in terms of quality, comfort, and price. We bought this alongside a King-sized ottoman and we could not be happier. Having used this mattress for just over two weeks, it's somewhat hard to believe, but we have slept-through the night every single night since we bought it, which isn't common for us! It is ridiculously comfortable, and just gets comfier the longer you lie on it. There is plenty of room to lie in comfort without disturbing the other person, and it doesn't seem to get too hot at night either. Despite the 1-star reviews - which I 100% disagree with - we have tried and tried to replicate the 'rolling over disturbs the other person' claim but it's just not true! The mattress seems to give a perfect balance when rolling over, and when awake or asleep, you can barely feel it. Once you're lying down, you just get comfier and you tend to stay in the same position without gettimg achey or fidgety which is great. I am a side-sleeper, and other half is a front-sleeper, and we adore this mattress. It suits us both perfectly. Our main concerns are that it is quite a tall mattress, so feels quite high off the ground/our bedside table at times (especially with our ottoman bedfeame), and extra deep fitted sheets only just cover the mattress on each side. We also just have a mattress topper, but are considering getting a full mattress cover (i.el wrap around the whole thing) instead, just to protect it that little bit more around the edges.

I wanted to use the mattress for a while before posting a review so after having slept on it for 2 months . - woke up after the first night and realised I got up without backpain. I have a crushed vertebrae and most mornings I ache so this was a good start. 60 nights later I have also discovered that if I have back pain after a day I go to bed and I wake up with less pain so the mattress is definitely aiding my aches very well. - I suffer from insomnia and yet again since having bought this mattress I have been sleeping so well that even those nights are getting less and less. When I do have sleepless nights it is so comfortable it doesn't bother me to lay awake and just listen to some relaxing music. I have medium firmness by the way. The one thing I have noticed is that the topper is not holding its shape all that well. It's only me using the mattress so that's a bit of a concern at the moment and something I will need to watch as the months go by. But after a lifetime of mattresses and back pain and sleepless nights this is the one and only mattress that so far has aided that THE BEST. Definitely worth buying if you have struggled with some of the same issues I have.

Delivery day felt like Christmas had come a week early. We spent hours in the Exeter store and the "regional floater", or, Corniche Steve I believe he said his name was. Excellent service and after hours of testing with combinations of pillows and a good 10 minutes on every other mattress, yes, EVERY, mattress in the store we were certain that this was the one. Took a few hours break and visited other local shops, none of which compared in quality of product, cleanliness of showroom or overall customer service. We returned a second time and headed straight fir this mattress and the rest is history. Took delivery today which again was a great experience. A call from the courier first thing to let us know today was still the delivery date, then another call an hour before arriving to make sure we were ready for them and then a quick and easy delivery straight to the bedroom. Benson, give Cornish Steve a bonus, he deserves it, and keep doing what you are doing. Your competitors are lacking behind and we will highly recommend you and your team to anyone looking to invest n their next bed. And now, if you don't mind, I'm off to sleep in this incredible bed for the first time.

This type of mattress was very new to me. I had my previous mattress for far too long and it was of the old style, 'standard' depth. So when I visited Bensons for Beds, both online and in person, I didn't know mattresses could be so high! I chose a firm mattress, because my previous mattress was semi-orthopaedic. I liked the technology of the Duo 1000 2-1 mattress and I slept on the 'warm' side. It definitely kept me warm during the night, to the point where I could sometimes push off the duvet! However, after a few nights, I soon realised that, as a 'side sleeper' I was feeling achy in my shoulders and in my hips when I awoke. I tried sleeping on my back and that was a bit better. I found that the firmness of the mattress was most suited to those who slept on their back, especially if you have a straight back. So I am very grateful for Benson's 40 night trial, which enabled me to return to their store and choose a medium mattress instead. Though expensive, it is worth investing in the right mattress for your body to get a good night's sleep, so you wake up rested, not achy. I shall review the new mattress separately in the near future.

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.
