Very nice very stabieles bed with simple assembly thanks to good instructions. Massive 80 mm wide center bar with two 50 x 80 mm thick Central supporting feet. If the bed is to stand stabiel total, one should at the Foot and head side two 3 mm holes in the center of the anchor of Mittelsterebe drilling and turning each one 4.5 mm Spax wood screw in. If that means board is engaged only in the anchor is the bed in Pages in motion not rigid! Everything great !! Thanks to Fa. Only wood !!
