Hart Black Plastic 4-Tier Shelf 36" W x 18" D x 53" H, Up to 600 lb Total Capacity

Awesome, versatile, but weight-limited per shelf. I originally bought two of these: one five-shelf and one four-shelf unit to set up our master bedroom for my wife's hospice time. They served to keep medical and related supplies for the nurses and techs I had coming in every day. After she passed away, I moved the shelving units to where I store my guns, ammo, and maintenance supplies. They are really useful and practical for a low-cost solution. For home hospice, the medical staff really appreciated the convenience of having all their supplies at hand near the hospital bed. The shelves were more than sufficient for med supplies. As for firearms supplies, the shelves are sagging a bit, but not to the extent of being unsightly. I'd estimate the shelves can hold 40lbs /- 5lbs properly -- Amm weighs WAY More. These shelves are so good that I bought another 4-shelf unit for my bonus room to store various items and two more four-shelf units for the garage to get stuff off the floor and improve the appearance of the stored items. Very versatile.

The item is well built and sturdy. I used to add storage to my closets. For the price it is a good deal and fits a lot of items. The holes allow items to vent. I filled mine with art supplies, documents, electronics and they are strong enough to hold all of those items. It allowed me to organize my space efficiently.
