After a home remodel I want to put up floating shelves on a large wall. I used to have Lacks. These were the older, more sturdy lack floaters in both sides with the posts in them I purchased in 2002. I had them up for 12 years and still have them. Problem is I need more. I purchased another for a bathroom in 2012 and it sloped with barely anything on it. My other thought is to create a rows of EKBY BJÄRNUM shelves spray painted in gold, staggering the connecting brackets for effect across the 145″ wall. I have heard however that the Ekby selves sag. Has anyone had any experience with the Long 45″ ekby shelves sagging when filled completely with books?
