    Mattress size vs frame size

    The size of a mattress and bed frame will always match; meaning a double mattress will fit on a double bed frame and so on. There’s no matching required with a divan bed, as it is a mattress and bed all-in-one.

      More bed buying considerations

      To me, to you

      There are two main considerations when choosing the right bed size.

      • Firstly, will it fit in the room of your choice? You might like the room and comfort that a larger bed offers, but how much space will that leave for any wardrobes or other bedroom furniture?
      • The second consideration is whether you can get it to its new home. Will the bed or mattress fit through your front door and up any stairs?

        Don't get cold feet

        If you’re a touch on the tall side, you might want a bed that doesn’t leave your feet dangling, or leaving you having to sleep diagonally. King size beds offer 10cm more length than a double, which might be the difference between waking up to cold feet or not.
