Project Source 5-Tier Heavy Duty Utility Shelving Unit

The frame is sturdy enough and assembly is very easy, but the shelves are 3/8” thick particle board which will deflect when a fly lands on it. Once the humidity is absorbed and any significant weight is applied, they sag significantly. Your best bet is to use the shelves to hold plastic bins that are greater that 24” deep (like an under-mattress box) so that the bin can rest on the metal frame instead of the shelf. Another option for smaller bins is to add strips of wood 25” long to place under heavy items. It’s a shame they cut costs so much to put out a product that can’t serve its basic purpose without adding some help to it. The oxymoron on the box touts “solid particle board”. Go figure. So I’d recommend the product if you go into eyes wide open knowing the shelving is inadequate, but it can be overcome if you adapt the use.
