    Product Details

    The Double CoolMax Superior Memory Foam Mattress is a favourite for side sleepers, with a deep luxurious layer of memory foam to sink into and a cooling mattress cover to prevent overheating.

    The deep memory foam layer moulds to the shape of your body, easing joint paint, relieving your pressure points and reducing tossing and turning during the night.

    The foam base below provides support and gives the CoolMax Superior Memory Foam Mattress a medium firmness rating overall.

    This memory foam mattress comes with a washable CoolMax mattress cover, which uses fabric technology to disperse excess heat and moisture for a cool, dry and more comfortable sleep.

    Brilliant Mattress
    Product was full size within 1-2 hours and the smell (which did not bother me) went in about 4 days. I now struggle to get out of bed in the morning! This mattress is far superior to any mattress I have tried in the shops and much cheaper! memoryfoamwarehouse were flawless with delivery, very quick and kept us well informed. Could not be happier with the value for money.
    Would never go back
    It took me a while to come round to the idea of memory foam mattresses. I was happy with my sprung mattress until I had to take medication which made me put on a bit of weight. I started to feel the pressure on my joints more and originally I bought a memory foam topper. But then my mattress developed a dip so i decided to go back to mfw for a new mattress. This one offers me a lot more support and the pressure is definitely less severe on my joints during the night. 5 star company, i'll be heading back around Christmas to treat my elderly mother who I know will benefit from this.
    Super duper!
    Excellent mattress and excellent next day delivery, except they didn't let me know when it was due to arrive. Luckily I was at home when it did. I unrolled it on the bed and left it to expand for a full 24hours. At first, I thought it was going to be too short, but when it was fully expanded it fitted a double bed perfectly. The mattress is deliciously soft, but not too soft for my weight. Right from my first night, I slept well on it and have never looked back. Lovely, and no longer have a stiff neck upon rising as with my old mattress. If you want a comfy mattress, look no further but make sure you buy memory foam suitable for your body weight. It still creates some heat in contact with the body, so if you overheat easily in bed, memory foam may not be right for you.
