There is a roll-up grille ... which one is to say big :)

Since this handet a rolling rust, so talk to a couple of wooden boards with two connecting strips can in my view not do much wrong. There are no zones, or the like, but who needs so precisely a roll grille is certainly well served with this here.

Advantage compared to other roll bar grates is the higher number and therefore the lower distance between the slats. He is supposed to be suitable for all mattress types according to the manufacturer. if that's true so I can not say. For our spring mattress anyway it is good.

All in all I can give a strong buy recommendation, the slats are relatively well planed and even after repeated use they hold. What you should ask for more.
