I have to say this is the first purchase I feel I was overcharged from Wayfair. The quality of this item was less than I expected. The book shelf I purchased should have cost 50.00 instead of the 138.00 I paid.  Each piece of the shelf is about a quarter of an inch wide and the backing of the shelf is cardboard. If you are looking for quality do not buy this. I bought this for my grand daughters books. It will probably last a year or two. Also be prepared to have to re drill some holes. Very dissatisfied.
