I’m mixed about these bookshelves. Good sturdy, heavy, adjustable. You don’t feel like the whole shelf is going to teeter over on you like some of the big store brands. Negatives the backside is that funny fold up cardboard piece. This seems cheaper than the ordinary cheap piece of cardboard that comes with most big pieces of furniture. We couldn’t get it to perfectly match and nail in correctly- so it bows in the back. Other than that- works for my kid! Pardon my boy’s feet in the picture.
