concluded between the mattress and slatted frame. Locking band prevents slipping. If you (in the supermarket for 10 cents) at the end side makes even 2 cable tie drum, it will not budge. The handle is height adjustable in 4 floors and in thickness and very good anti-slip material for gripping. I (91 years) attached to the top and at the bottom end of each one, so that it can stand alone and is simultaneously secured against fall out with my father. If person about 90-100 KG (also depends on the mattress from because the resting yes and this results in the counter-load) is not about (estimated), Rec Gehlen value. Persons over 100kg, I would want to try it for now. Is identical under different names offered much more expensive, so misnomer to drive the price up.
