You'll wake up feeling refreshed every morning after a night on one of our king size mattresses. With the many advantages of restful sleep, from improved concentration to a whole range of health benefits, a new king size mattress might be one of the most important investments you will ever make. And at such a luxurious size, there should be ample space for both you and your partner to stretch out, relax and snooze in comfort.

Our 5ft king size mattresses range from memory foam, no-turn mattresses to the superlative support of our orthopaedic mattresses and responsive pocket-sprung mattresses, with fine covers of cashmere or silk, and luxurious fillings such as cotton or hand-teased lambswool or horsehair. If joint pain is a concern, you may want to choose a memory foam mattress, which moulds itself to your body shape. For superior comfort levels, you could go for latex and pocket springs. Those who favour a firmer, harder surface to sleep on might prefer an open coil mattress - it's a more traditional choice.

And there are still more ways to make sure your new mattress is exactly what you need. Take a look at our in depth mattress guide. It's also reassuring to know that many of our our mattresses are dust-mite resistant and hypo-allergenic - welcome news for allergy-sufferers.

With a range of support levels, from soft through to very firm, available across all the big brand names, you're sure to find something that will suit you perfectly - especially as our mattresses will fit standard UK bed bases.
