Ideally this was great for a newborn or baby who can’t pull themselves up yet. I went to lower the mattress and the piece that the screw goes into all came out. Stripping the hole so even if I were to get the piece that goes into the hole out and try to screw it’s in it wouldnt hole unless I put wood glue to hold it in its place. Not happy and am going to call to see what they can do. Great product until you have to lower.
