I purchased 3 of these cabinets to update  a walk-in closet from H. I could not believe the prices for closet systems of basically the same exact material. Its all fiberboard. They each took me (a small, middle aged, female) approximately 4 hours each, using a power screwdriver and moving slow. I felt the directions were pretty good. Not difficult, just time consuming. The assembled cabinet pieces, being a top and bottom, are very heavy. I moved them upstairs before putting the top on the bottom. I was able to drag them up my stairs but it was tough. They are pretty solid, for the most part. Well put together. I would avoid moving them or over-loading them. Theyre not solid wood. Theyre perfect for a storage cabinet, closet insert, etc. Nothing fancy. I am using them without the doors for now and they look fine. Also, the two parts could actually be modified to two pieces, used separately. Theyre not meant to but def could.
