Note: Mattress thicknesses can differ greatly, but the average depth is between 25cm and 30cm. Please check the specifications of the mattress you are interested in, to ensure it suits your needs.

Hint: Always buy the biggest bed you can. The more room you have in your bed the better quality of sleep you will have, especially if you're sleeping with a partner. Two people sleeping together should select a queen or preferably a king size mattress and base to ensure both individuals have enough space for a good night sleep.
