This is a light weight, plastic unit. It was very easy to fit/ install, no tools needed. All layers could be used, or isomer could be left out if all were not needed. The wheels were optional ie could be fitted or left off. The wheels moved smoothly and the unit was stable. It was purchased for the bathroom and the curved handle on one side was a useful / practical design to hang a towel from. The base of each shelf had small breathing/venting holes. The material was a matt plastic. Unfortunately it did not suit the room as it looked to casual in terms of style (mainly due to the obvious plastic material), wanted something smarter so had to return it. However, would still recommend it as it was very stable, practical, easy to fit, the height and wheels could be added/removed, it can be useful for storage in the bathroom, study, kitchen, garage, for books, toys, nick nacks. Would buy again (this time for the kitchen) if need more storage.
