I needed to add shelves to a 10.125" wide section of a large, wood storage rack I have in my studio for canvases, but I didn't want to alter the wood rack permanently. I was having trouble finding anything narrower than 12" and then I found this product. The 10" wide rack fits the width of the space perfectly and I can slide it out easily in the future if I need the taller space again without the shelves. It would have been a bit too tall for my space with all four sections, so I eliminated the upper poles and one shelf, for a total finished height of about 42". However, the space I have is quite deep (about 38"), so I just ordered a second one in the same 10x16x55 size that will result in the shelves filling almost the entire depth of the space. It will be perfect then for storing smaller canvases and art panels.I found this extremely easy and quick to assemble, without any assistance. I should add that I am in a wheelchair, so if I can do it from a seated position, with arthritis, bad shoulders and lousy balance, then anyone should be able to do it! I had read quite a few reviews before purchasing it, including some complaints about the shelves not going together or holding properly. If you follow the instructions, it should assemble without any of those problems.There were also some complaints about having to assemble it with the flat side of the wire shelves down, resulting in shelves that are trays, rather than flat shelves. I did not encounter this problem, either. I was able to assemble it with the flat shelves up, so I will have nice, even, long, flat shelves (10"x32") once I set the second rack flush against the first one.This metal rack is strong and sturdy and should hold a substantial amount of weight, although I don't know that I would feel comfortable testing it with 120 lbs per shelf, as the product listing indicates, simply because the clips that hold the shelves in place are plastic, not steel like the rest of the rack.Overall, though, I think it's a great value for the price and I would purchase it again. In fact, as noted above, I already did!
