Sturdy when loaded but it is made of MDF board and is not as nearly as solid as a piece of real furniture. However at a savings of more than $550, I can live with that. Assembly was flawless and to about 2 and a half hours. You will need two people to move this one assembly is finished. Color and finish is very aesthetic, and it holds a lot of files. Drawer slides are very heavy duty and similar to real wood filling cabinets that I viewed.
