Do you have enough space?

  • Using a measuring tape, size up your bedroom or available space
  • Make sure the mattress size you choose can fit comfortably in the space
  • Factor in additional space each side of the bed if you use bedside lockers
  • If you’re sizing a mattress for an existing bed frame, make sure the length and width of the bed frame and mattress is the same
