I am very pleased with this folding bookcase.  It was the easiest thing to put together, lol!  All you had to do was open the sides and pull down (gently) on each shelf to fall into place.  NO TOOLS NEEDED!  Love, love, love this bookcase.  It holds more than I expected, considering it is on the small side.  It arrived in less than a week.  Thanks, Wayfair!
