King Size Memory Foam Mattresses

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.
