Mattresses are to confirm to bed sizing and dimensions
A mattress topper is a thin mattress, usually 5–10 centimetres (2–4 in) thick.[citation needed] Stand-alone mattresses of this size exist (see futon and Bed base#Floor beds; traditional European beds were made of a stack of mattresses of this size). But "mattress topper"s are usually sold for use on top of boxsprings (secured with straps or elasticated cloth corners[8]).
