The standard size for a UK Super Kingsize mattress is 183 x 200 cm / 6 ft x 6ft 6in. As you can appreciate it’s worth investing in a good quality mattress because we spend a third of our lives in bed. It is a challenge to make the right decision on which Super Kingsize mattress to buy because the mattresses vary in construction and the amount of padding. The Which? report states that the average person spends £800 on a mattress. However, rest assured that this site features top quality mattresses to suit all budgets and requirements. Argos and John Lewis have competitive prices on brands such as Airsprung and Silentnight mattresses.
