Safety aspects regarding combination of side rails and mattresses.
In order to obtain the highest possible safety level, when using the bed in combination with side rails, it is important to respect the
minimum and maximum measures for mattresses stated in the table.
To mitigate the possibility of the user crawling over the top of the side rail, with the risk of severe injury due to e.g. falling, a mini-
mum vertical distance of 22 cm between the top of the mattress and the top of the side rail are to be respected.
The maximum mattress height in combination with a given side rail is stated in the table.
To prevent head entrapment between the inside surface of the side rail and the mattress, with the risk of e.g. suffocation, a safety
maximum space has to be respected. When especially very thick mattresses or soft mattresses (low density) or a combination of
these it is important to focus on this risk. The minimum width (and length) of mattresses in combination with a given side rail is
stated in the table.
