Which firmness rating should you order?
Regardless of your chosen firmness rating, the top layer of your mattress will remain the same. This means you’ll still enjoy the same level of comfort and pressure relief that you’d expect up top.
When you upgrade to a firmer feel, the bottom layer is swapped for a more supportive, higher density foam. This helps to provide you with a better level of support, as well as preventing you from sinking into the mattress as much.
For those that like their mattress to have a little more ‘give’, the standard firmness rating is usually the preferred choice.
Weight considerations
Under 15 stone?
If you weigh less than 15 stone, you can opt for any firmness rating providing your mattress has a thickness of 13cm or above. If thickness is less than 13cm, we recommending upgrading to our firmer feel for enhanced support.
Over 15 stone?
If you weigh 15 stone and above (but less than 20 stone), be sure to upgrade to our firmer feel for enhanced support.
Weigh more than 20 stone?
If you weigh more than 20 stone please contact us to discuss your requirements.

ComfiCel® Cool Memory Foam Mattress
Welcome to the cooler side of the pillow. Perfect for increasingly warmer summers and fiendishly cold winters – ComfiCel Cool retains less heat in the summer, whilst remaining perfectly cozy throughout winter. Adapting to every curve of your body, Cool memory foam gives a plush cushiony feel with plenty of support. We spend 1/3 of our life in bed so this is for those who intend to love every second!
Sleeps cooler
ComfiCel Cool uses advanced open cell technology that retains less heat than traditional memory foam making it prefect for those who like to sleep cooler.
Enhanced pressure relief
Our Memory Foam and Gel Foam mattresses both offer great pressure relief, but our Cool memory foam goes above and beyond both of these and provides a higher level of pressure relief that takes you to a whole new world of comfort.
Faster to respond
Memory foam can be slow to mould to your body. Our ComfiCel foams won’t leave you waiting and begin adapting to your unique shape immediately.
Better freedom to roll
Regular memory foam reacts to changes in temperature which can make it slow to bounce back. ComfiCel foams react to body pressure instead allowing them to start recovering instantly.
Pressure relieving
Old fashion springs push against your body with equal force meaning pressure points are inevitable. Our memory foam is different, distributing body weight more evenly and reducing pressure … ah, now thats better.
Cloud like support
This mattress provides a medium level of support perfect for a wide range of different sleepers. If you’re heavier than 15 stone (or just prefer a firmer mattress) be sure to upgrade to the firmer feel so you stay properly supported.
Less rolling together
Sleep through your partners disturbances and let them roll around guilt free on a mattress that isolates movement.
Two comfortable layers
They say two’s better than one, which is why your new mattress has been made with 2 layers – a cushiony layer on top and a firmer more supportive layer at the bottom.
Durability built in
Our mattresses are designed to give you 5 years of amazing everyday sleep – we’ve even backed it up with a 5 year warranty for peace of mind.
Zip off cover
Mistakes happen and should you spill your favourite cup of tea all over your new mattress, just unzip the cover and clean it with ease – simple!

Im very happy with my mattress it’s firm but still comfortable,we had one the same for the caravan..
Brian –
Cool Blue double nearly 4yrs old now, still an outstanding kip.
Just washed the zip cover after over 11K hours sleep (says the calculator). It seriously needed laundering, bloke sweat stains due hiccup in blood pressure meds. 4hrs soak in the bath with that Oxy powder stuff, coolish machine wash & dried easy overnight. Cover fetched up almost like new, well impressed. Was thinking of asking Myles for a spare cover but no point, the cover is simple wash & wear.
Foam base has an “aged” colour to it hence 4 stars but don’t care. Lovely sleeping throughout the four seasons.
Les –
This is the second mattress purchased in the last 12 months, first was for the motorhome and this one was for a double bed as they are very comfortable 😴.
Patricia Spanswick –
We received the bed very quickly, pleased with quality but are finding a bit firmer than the one we had for the caravan but guess it will improve with time. We had very good service and would recommend to our friends and family.
Debi –
Fabulous company to deal with and a brilliant mattress. This is our second purchase as, like many others, we bought a custom fitted mattress for our Campervan and were so impressed that we bought a superking one for our main bed at home. It is much more comfortable than the very expensive sprung Hypnos mattress that it has replaced.
Zoe –
Such an efficient service and such a comfortable mattress! Highly recommended
Elaine Turner –
We bought this mattress for our family’s caravan and we were the first to use it. We both slept very well on it and will certainly buy another when needed. An excellent firm to order from.
Jo Kluzniak –
This is the second mattress we have ordered. We first had a custom fitted one for our motorhome and we so impressed we ordered a king size for our bed at home. Such beautiful crafted. Really comfortable nights sleep. There customers service is brilliant and delivery was quicker than I expected. Would definitely recommend to friends and family.
Lisa –
second time I have ordered from here. very pleased with item
Marcus Murray –
Delivered very quickly considering the current pandemic. The team were extremely helpful and friendly with the ordering process. Considering the mattress is only 10cm thick, it’s very comfy and would certainly buy again if needed.
David Perry –
Great product, delivered on time! Slight chemical smell which disappeared within 3-4 days. Very comfortable, would highly recommend.
Derek Walker –
Excellent product, excellent service. We bought a custom sized mattress last year to replace the one in our caravan. The time and trouble taken over the order was impressive.
Delivery was tailored to our timing. The mattress proved so comfortable that we decided to go ahead and replace the one on the bed at home. Wonderful.
Janice Hopwood –
For twice as much you can buy well-known, much advertised brands of memory foam mattresses. Each claim to be “the best” “the most comfortable” “have no roll or sensation of your partner moving”. Each claim to use the latest in foam technology. But why pay double the price, or more, just for a fancy name, when you can have the same quality of mattress for so much less? I have used Custom-Size mattresses on several occasions now, most recently to purchase two Super King Sized mattresses (one for my guest room). The 10″ deep Cool mattress is, in my opinion, better than the leading brand. It’s not too firm (although you can add a firmer foam to your order), it’s not too soft, it’s not sweaty. Both my husband and myself have been sleeping like babies and it has certainly been beneficial for my bad back. You will not be compromising quality over cost. It will be a purchase you can rest assured on.
Sheila –
At last a comfy foam mattress that doesn’t overheat the sleeper.
Elizabeth Hughes –
We ordered two mattresses for our canal boat and were so impressed with the quality and customer service that we ordered two for our home as well. Our order arrived very quickly and took us by surprise one evening. We would definitely use this company again.
Carolyn Blackham –
I came across this company just by browsing for cool memory foam info. I had been in one well known bed shop and felt overpowered by the assistant so that put me off. There’s no way testing a bed in a showroom would help me make my mind up. My old mattress must have been about 15 yrs old, sprung with no more spring in it I tried to make up for that by putting on a memory foam topper. I liked the look of this one and after a chat with Myles, decided this one was for me. The reviews were excellent so a bit impulsively for me I placed my order. The bed arrived after a couple of days and I was notified by text of the time of delivery which was excellent, almost to the minute. My first night I wasn’t sure and thought the mattress was too firm but in comparison to my old one, anything would have felt that way. After my third night I can say I made the right choice. This mattress isn’t going to make my sciatica go away but at least I can be more comfortable. Neither is it suddenly going to change my sleep pattern and allow me to sleep through the night but at least I’m awake in comfort. In my opinion this is an excellent company, first class advice from Myles and no fuss delivery and all at a very reasonable price.
Colin –
Got the cool memory foam mattress for our Motorhome used it for a season and it’s great and next day delivery will be getting a mattress for home
Barby –
Excellent service, arrived in a couple of days from ordering. No more for me a twinging back when out in my motorhome and the sprung mattress is back in the spare room where it belongs.
Janet Webb –
Lovely mattress. Very comfortable and seems to be cooler than my previous mattress. Excellent delivery on specific day requested.
Stephen Calder –
This is a lovely mattress, firm and supportive yet there is none of that horrible sinking-in feeling you get with other memory foam mattresses. Most importantly for me, I don’t get hot, which is a big plus.
Sue Richardson –
After lots of sleepless nights on our very hard Globecar bed and much experimenting with feather and down mattress topper and then a memory topper on top of that! I began my search and came across custom size beds and had a very lengthy and informative conversation with Myles
We decided to go for the mattress hoping that this would be the answer.
I have had spinal surgery so it was very important that we made the right choice
The Globecar mattress had quite a few irregular cuts and that was causing a problem also.Myles suggested we draw a template and email that to him this was not a problem for this company.
The mattress was promptly delivered and we have just had our first weekend with it fitted …WOW amazing I cannot praise it enough,when I took delivery I thought it felt very firm but believe me it was so comfortable also I noticed unlike the memory foam topper we did not get too warm
Would highly recommend this company and would like to take this opportunity to thank Myles for all his help and for supplying so very quickly.
Phil Hopkins –
We have two mattresses ComfiCel Cool Memory foam type which are excellent great value and extremely comfortable I have no problem recommending them to any one, delivery was also perfect and reached us within days of the order.
Vanessa Littler –
I received superb help and advise from start to finish!
I wanted a replacement mattress for my motorhome which was not a standard size, after much searching I decided to use customesizebeds due to the variety and price of their mattresses. Once I had made my template, which was easily made by drawing around the existing mattress, I sent it off and received my new mattress within a week. I was not sure if the Cool Memory Foam topping would make a lot of difference but it provides a cool and comfortable nights sleep which can be essential in a motorhome. The service I received was outstanding with fast responses to my (many!) email’s. I wojuld not hesitate in recommending this company.
Milly Peart –
We bought our custom mattress as we’d had a custom made bed built for one of our children to fit in a small bedroom. The mattress is incredibly comfortable and soft, a decent thickness and was made and delivered ridiculously fast!!
The customer service was first rate and ordering this mattress was so simple. I would definitely recommend using custom size beds to anyone and am actually looking to get two more mattresses from here in due course! I liked the idea of a cool memory foam as memory foam is known for making the sleeper too hot. This for children will be perfect. All the support but without the overheating. Oh and the price was one of the best I found on the interent for the service and quality we received so all in all I’m very pleased and extremely satisfied!
Many thanks
Rebecca –
I bought two of these for my daughters aged 10 & 16 and have been delighted with them. Both girls have hardly left their bedrooms since we bought them! I can’t believe we persevered with sprung mattresses for so long. Excellent quality and good value – we received excellent service and quick delivery. I will be recommending these to my family and friends.
Mrs C G –
After extensive research, phone calls and bed-sampling in shops, I decided on this mattress and I’ve not been disappointed! I’ve been suffering from lower back ache for a few years due to the difference in weight between my husband and I – I’ve been sleeping on a tilt as my old sprung mattress was well past it – but a recent back injury has purged me on to buying a new mattress,
The reason I went for this mattress is because it is a very similar match to Benson’s iGel Apollo, which I identified as being my favourite when trecking round the bed showrooms. I’d decided I didn’t want another sprung mattress as they’re too bouncy and as a light sleeper I’m far too aware of the movements of the other person in bed. It’s quite firm so there is no rolling into the centre, you are extremely unaware of the other person in bed, and at the same time it is very comfortable as the cool memory foam topper gives the same sinking sensation as memory foam, only it responds far quicker so you don’t get stuck in your imprint. Cool Memory is also not heat retentive like memory foam either, so you don’t get too hot in warmer weather.
At a fraction of the price of anything you can buy in the shops it is well worth buying one of these. My only conern was the amount it would cost me to send it back if I didn’t like it (courier cost plus re-vacuuming cost) but I decided that if I hated it I’d just use it in the spare room instead!
I would rate this mattress as being on the firmer side of medium, supportive, comfortable and most importantly – no back ache!
I should also mention that delivery was very quick – next day! And once unwrapped it expanded into shape almost immediately, we slept on it that same night. I should also point out that there was practically no smell like some reviews I’ve read. I had to press my nose right in to sniff it and even then it was just a mild clinical smell that didn’t linger at all.
My advice: if you’re looking to buy a foam mattress for the first time, do some research first on the differences between memory foam, Gel foam, cool memory foam and latex so you know what they all are, then go trying out beds and see what ‘feel’ you like best. There is a website that I found with extensive information, videos and comparisons to branded beds, as well as very helpful staff when I phoned up, but I cannot mention them here for obvious reasons! Just search online, there’s lots of information out there.
However, I can say that I also phoned Sensation Sleep on a couple of occasions for information and they too were very helpful and informative about the foams, except I chose a different one to their recommendation, based on my own research.
I am very happy with my purchase and am finally experiencing comfortable sleep! As for my husband, he can sleep on anything!
