What is the best King Size Mattress?
The best king size mattress is the one that suits you best! We often get asked this and because everyone is different there is no right answer. Some people prefer a firm king size mattress, while others prefer something softer. Some like the warmth and comfort of a memory foam mattress, while others prefer the cooler feel of an open coil or a king size pocket sprung mattress. For those who want something in between, a king size hybrid mattress is an ideal choice.
What size is a king size mattress?
A king size mattress is 150cm (5ft) x 200cm (6ft 6). If you like to stretch out, move around a lot, or simply want plenty of space, a king size mattress is a great choice. Although only 6 inches wider than a standard double mattress, you will really notice the difference.
