This unit is a good value because it includes the top. Its a good thing it is well packaged because its construction is really light weight. The material is MDF (Medium Density Fiberboard) which is prone to cracking and breaking. Our unit arrived it good condition. It is held together with plastic brackets which are stapled in place. We added glue and metal brackets to strengthen ours. Drill your screw holes first as screws will fracture thus material. The top wobbles on the cabinet so its necessary to shim it before using any adhesive to hold it to the cabinet. Do yourself a favor and us a good construction adhesive like PL Premium to attach the top to the base. The doors come with nice self closing adjustable hinges and its a good thing because the doors were out of alignment when we received it. Overall a nice unit and we recommend it!
