Coolmax Memory Foam Mattress Zipped Cover Size - Double 4ft6 x 6ft3 Depth: (5" - 12.5cm)

Really good quality and would highly recommend.

Arrived as promised, looks great quality, better than I thought it would be, i thought i was taking a risk at first with spending so much on what is essentially a mattress cover but its worked out really well I have a 10 inch mattress with a 2 inch memory foam topper and this combines the two together into a single block, so looks and feels like one mattress now not 2 separate ones The fit is perfect, i ordered the 12 inch as that is the size i measured, a size lower would have fit too but this way the cover can flex when i lie on it and sink into the mattress without stressing the material, it isn't snug or tight but it certainly isn't loose either highly recommended, will be getting another for the other bed

Not wanting to dispose of our memory foam mattress we decide to buy a new cover ..... this one in particular! It fit perfectly as good as the original but what we have noticed over the last few weeks is the ability to restrict heat from the mattress. This is one of the downfalls of a memory foam mattress but to our delight the whole sleep experience has been fantastic and comfortable particularly in the hot nights we have had lately. My wife is so delighted with this product and at the price it is an absolute bargain ..... Perfect or should I say COOL !!

I got this cover to protect a SilentNight memory foam mattress I recently bought ( and regretted ever since!). The cover is well made and fitted easily. I would say, as others have to buy one size down for a better fit i.e. my mattress is 5" deep, should have bought 4" for a tighter fit. Having said that it's not bad as it is. As for the temperature claims, I don't notice any real difference: bed is still too warm at night.

Bought this Coolmax memory foam cover a few weeks ago and I’m genuinely impressed. It fits snugly over my mattress and topper, giving it a clean, unified look. The material feels breathable and noticeably cooler than my old setup—no more waking up sweaty! Zipper works smoothly, and it’s easy to remove for washing. Only minor gripe: fitting it solo was a bit tricky, but once on, it stays put. Great quality overall and definitely worth it for a better night’s sleep.

The topper ws nowhere near 5" thick, Would have gone with the thickest if I knew.

We replaced our mattress on our main bed as it wasn't firm enough but there was still loads of life left in it so we cut it down to a standard double from a king size as its 100% foam and memory foam but the cover was destroyed in the process. Bought this one and went for the size down on the thickness as others have said and this turned out to be a perfect choice. This has been in place now for nearly a year with daily sleep and still looks brand new without any signs of wear. Would definitely recommend this!

I followed the other reviews and ordered a 4" for my 5" mattress and it fitted perfectly. Can be a slight pain to get on by yourself but it works great. Very comfortable and a lot cooler than what I had before. I have already recommended it to some friends and flatmates. I have had it for a few months now and no sign of it stretching any further or becoming loose and it is very easily washed if anything is spilt on the mattress.
