The wood frame and shelves fit together to form a sturdy, yet light weight storage unit that is very attractive. Since we are using this in a children's room, we have securely fastened it to a wall to prevent tipping. As noted by other reviewers, this item is somewhat difficult to assemble. I found that by using a band clamp to hold the partially assembled until everything could be fastened it was possible for one person to assemble the unit without any assistance. The instructions are not completely clear concerning the orientation of some pieces. Look at it carefully as you put it together. Some pieces may need to be turned around for the fasteners to go in properly.
