I purchased two of these bookshelves based off the positive reviews on Wayfair and am extremely happy with the purchase. I assembled and mounted both to the wall by myself in about 90 minutes. The instructions are easy to follow and assembly does not require tools (minus the allen wrench provided). As far as quality goes, it surpassed my expectations. Yes, the shelves are MDF board and have a veneer covering, but they are heavy and do not look nor feel cheap whatsoever. Definitely recommend this product.
