Ensure you buy mattresses with dimensions that are recommended by the manufacturer.
It is particularly important that you get the right mattress for the raised/upper bed. There will often be an identifiable mark on the rail indicating the maximum mattress height allowed. This is to ensure that the effective height of the safety barrier is maintained to prevent children falling.
