We wanted a large bookcase that would hold lots of books with shelves that wouldn't bow under the weight. We were not disappointed. This is a really sturdy set of shelves!!  We went for the 5 shelf unit rather than the 4 shelf unit.  Sadly at the time we bought it, the 5 shelf unit is only available in white or a grey stone finish, whereas beech or a similar wood finish (as available on the 4 shelf unit) might have been nice.

Ordering through the Wayfair website was easy and the delivery time was about 2 weeks faster than they estimated.  Everything arrived undamaged and all the bits needed to complete the unit were in the box.  It took about 2 hours to assemble at a fairly easy pace.  The instructions are just a few sheets of illustrations so there was a bit of head scratching at times.  It built up into a really nice unit and we are very pleased with it.
