For a superb night’s sleep you need the right bed – and it is hard to find any mattress more comfortable than our selection of king mattresses.
5ft king size mattresses are not only wider than a UK standard double mattress; they are also 3 inches longer. The additional 6 inches in width may not sound a huge gain, but when sleeping it can make all the difference to allowing you to stretch out comfortably, or give you that extra moving room when you are sharing a bed.
If you are looking for something larger, check out our super king size mattress section.
Our king mattresses are available in many styles including pocket sprung, open coil and orthopaedic. We currently have big discounts on many products and all our items are covered by our free delivery service.
