If you definitely want or have to use your mattress there are two options:

  1. You can change our queen size mattress for an Australian double mattress. Please note that you will have a 6.5cm gap on both sides of the mattress and a 3cm gap on the top of the mattress.
  2. If you have a foam mattress you can have it cut to size. Nowadays, foam mattresses are very simple and cheap to cut.
