Safco 5390BL Mobile File Cart Organizer with 9 Shelves & 4 Wheels - Letter Size Storage Cabinet for Office, Home & Classroom Organization - Black | Perfect for Document Storage, Teacher Supplies & Office Filing Systems

One of the better designs for organizing paper.The wood material is cheap as expected for this price point. The paper slides glide on plastic with metal pegs. Should probably add some kind of grease to keep the friction down.Was easy to put together, would recommend using a power drill on lowest setting. Then hand tighten towards the end.Maybe upgrade casters, if you load it with a lot of paper.I took away the top plastic trays and added another organizer on top of it to hold 13x19" paper.If the compressed wood starts fatiguing from use, then I will just reinforce it.
