Easy to put together with either a drill or plain screw driver. The holes were all pre-drilled in the right spots. It took me about 15 minutes to put it together. AFTER I read the directions correctly. Make sure you have the top and bottom frames on correctly or the top and bottom doesn’t fit in the bookcase correctly. It will work but you won’t be able to fit taller items in. ￼I had to take it all apart and start over but it was a quick process. It will fit tall books or record albums perfectly.￼ It looks nice but remove the stickers carefully because the particle board scratches easily.￼￼ Five stars because of the price and ease of assembly, and also because it was one of the best things I could find for vinyl record albums. Four stars for the laminate paper on the particleboard.￼
