I gave this one star less only because the assembly aspect was long process.  All pieces were there, but definitely dedicate some uninterrupted time to get it together.  We were stuck at home due to a situation, so I had no interruptions.  I also had a big bottle of wood glue, and a damp towel for glue wipe-up.  I use them in front door hall way for shoe storage.  They work great for that. I could see several for book storage, but there might be an easier option for jus books.  I needed their height, depth, and like front lip so it holds items in.  I'm very pleased with these.
