King Size Memory Foam Mattresses

based on 8 reviews Rated 4.3 out of 5

A king size memory foam mattress allows you and your partner to get the individual support you need without disturbing each other’s sleep. A memory foam mattress will distribute body weight evenly, increase blood flow and reduce pressure points – all of which contribute to sounder sleep.

Ideal for those with back problems as well as allergy sufferers, our 5ft-wide king size memory foam mattresses are made with high-quality materials and fillings, while remaining affordable and great value for money. Some of our memory foam king size mattresses come with memory foam pillow tops for extra support or two free memory pillows, saving you even more on cost.

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. These innovative mattresses will fit all standard UK divan bases and bed frames – or why not indulge yourself and choose a brand new bed with memory foam mattress from our range. Order now online – it’s quick and simple – or call our friendly team on 0800 035 0070.
