We have an extensive collection of kingsize mattresses for sale. If you are looking for a cheap low cost kingsize mattress then take a look at our open coil, medium support mattresses - superb for a spare room and fantastic value. They come beautifully upholstered in a damask cover and equipped with an edge guard which adds durability to the mattress.

Our most popular king size mattresses combine pocket springs with memory foam- a heat sensitive material. It moulds to your body contours, providing support and eliminating pressure zones which ultimately reduces tossing and turning during the night. Mattresses are available with up to 100mm of memory foam using densities up to 85kg/m3. This is high quality material from reputable manufacturers in the UK.

If you want a different type of mattress then choose from reflex foam, visco elastic memory foam, latex or a traditional kingsize pocket sprung mattress - all these at tremendous low cost prices. From orthopaedic to super soft, we have them all.

All our kingsize mattresses are designed to fit UK beds. The dimensions are 150cm x 200cm, ie 5ft x 6ft 6. If you are interested in furnishing an entire spare room or moving house then consider our king size bed frames and bedroom furniture ranges as well.

If you need a European IKEA size mattress (160cm x 200cm) - phone us - we can get you a high quality 160cm mattress at very affordable prices. Also remember to take advantage of our next delivery service that is available on the majority of products.
