Active replacement air mattresses, are by their very nature light and easy to move. This means that if the mattress is not secured to a bed frame it could easily slide off. This applies to divan beds as well as to adjustable or medical beds. In fact, adjustable bed frames are designed to profile. This movement can cause the mattress to slide off the bed frame.
Squirrel active mattresses come complete with securing straps which are built into the base of the mattress. These must be attached to the bed frame in a manner that prevents the mattress from sliding off of the bed frame. Care must be taken to ensure that the securing straps do not impede the action of the bed frame. Also, that moving parts within the bed frame do not damage the securing straps. Overlay air mattresses will need to be secured to the base mattress.
