The instructions are very confusing. It took me almost 3 hours to just put the shelves together. Ended up getting rid of and not using the "durable" protective cover for 2 reasons: it wouldn't go on the shelf despite trying everything for over an hour and just when I thought I had it, the side ripped out a bit and a zipper fell off. Very disappointed. This was the worst item I've ever had to put together from Amazon. Do not recommend this item although it is pretty strong unless you have a whole day to set it up and the patience of a Buddhist monk. Lol. To me it wasn't worth the money spent on it.
