Buying a new mattresses can be unnecessarily confusing. Every retailer seems to have their own standard mattress sizes and when you throw in that different countries call the same mattress by different names, it’s enough for anyone to lose sleep over.
That’s where we come in.
We’ve put together a guide to help you find the right mattress for you and we’ve started by explaining the different mattress sizes available in the UK.
Below you will find the seven standard mattress sizes available in the UK: single, small double, double, king, super king, cot and cot bed and their standard size measurements.
The size of mattress you need will depend on your circumstances. How many people will be sleeping in the bed? How tall are those people? How much space do you have in your bedroom? Below you’ll find the different mattress sizes and who each one is best suited to.
Width: Lie on your back with your hands behind your head and your elbows sticking out sideways. Your elbows should not touch the edge of the bed or your partner.
Length: The mattress should be 10cm longer than the tallest person who will sleep on it
