About King Size Memory Foam Mattresses

Memory foam mattresses offer comfort and support where you need it most to aid a restful night

A king size memory foam mattress will allow both you and your partner to get all the individual support each of you needs, without disturbing the other's sleep. Memory foam is an advanced material renowned for its ability to mould to an individual's size. Body weight is distributed evenly, which in turn increases blood flow and reduces pressure points. All of that contributes to sounder sleep, as well as promoting good blood circulation, allowing tired joints to relax and helping to improve posture.

Choose from our range, and you can be sure of high quality and impeccable craftmanship. We also offer hypo-allergenic fillings and temperature-responsive features. Coolfeel fabrics ensure you won?t suffer from nocturnal over-heating, by combating the humidity built up by the body during sleep. Blu Cool memory foam is a technologically advanced new material foam designed to keep temperatures moderated - essential for really deep, restful sleep. Memory foam mattresses never require turning - a particular bonus when dealing with a hefty, king size mattress Our range will fit most UK bed bases, and come in a wide range of support levels. So whether you like a firm support or prefer to luxuriate in softness, we have something to suit.

As we are able to source our king size memory foam mattresses straight from the manufacturers, we can offer you excellent value from many of the top bed-makers, with years of knowledge and expertise in crafting beds and mattresses. We stock leading big-name brands, so when you select your new memory foam mattress from our extensive, carefully selected range, you'll know you're getting excellent quality, as well as outstanding value for money.
