I've put together lots of furniture with little problem but this one was frustrating. The first section went together without any problems except that the top screws were too short. The bottom part was a real pain. The holes were not aligned so I figured I just wouldn't use the back pieces. I went on to attach the shelves and could only put one on....there was not enough hardware of the correct size hardware to be found. This can't be used. Lately have been very disappointed in Wayfair quality.UPDATE:  Does anyone have a suggestion what I can use to for parts A & B so I can attach shelves: Will drill holes that will line up. Used liquid nails to secure back pieces....hope it works.
