For the user's safety and to reduce crushing damage, the size of the mattress must be adapted to the recommendations of the bed manufacturer. The same recommendation applies to both air and foam mattresses.

If you choose a mattress that is not adapted based on the recommendations of the bed manufacturer, for example using a mattress that is too small, this means that the mattress may slide, the bedsheet may not lie still and there can be creases. The risk of injuries may also increase, for example the risk of the user squeezing the foot between the mattress and the gate, which can lead to pressure injuries or other injuries.
