UPDATE July 22, 2020 - latest purchase. Wonderful except I almost told USPO to take it back when a woman behind me in line offered to take it to my car. I did not go to Post Office to retrieve this item but to mail seeds from China. I could not lift box and had a real struggle dragging it from my car. Probably will try to purchase any additional Origami units from a different entity (I walk with a cane) or have it automatically returned to Amazon if not delivered by UPS or other carrier. This, however is a lovely unit. I now have 7.UPDATE May 6, 2020Recently purchased 2 more in rose gold for my loft; these appear more pink - which I prefer anyway - and look wonderful. The wheels were included but not assembled which I prefer. I bought these to hold smaller books so that my coffee tables are not loaded down with books I frequently read and refer to. I already have in a steel color similar to stainless, 3 in my kitchen (which is tiny but not a galley) to hold additional pots, pans, and other items so that they are more accessible, and another in my great room which holds large art books. At one time one could purchase magnetic liners which are wonderful for books but the last time I checked they had been discontinued. I absolutely love these Origami shelves. No assembly required. They are beautiful and I would purchase again.*******************************************************Love it. This so-called steel storage rack (Origami) works beautifully in my bedroom. It is being used as a small bookcase for a collection of heavy, leather bound art books which feature the biographies and works of various painters. To my surprise, the two lower shelves held all of the books. The top shelf holds a large coffee table book on Mary Cassat, an American impressionist. The only thing I had to attach to the shelf were the wheels, which was really nothing to do (a tool was included too). I did not need bookends (I juxtaposed a couple of the books at the four ends of the lower shelves instead). The shelf blends in nicely with my eclectic pieces of transitional furniture, which include a bronze colored metal, marble, iron, cotton, and wood, including a vintage telephone and a large, framed contemporary print. I had planned on purchasing another case but did not need to. This shelf, although holding some weight now, is well made and does not appear that it will falter in any respect. If I find time to straighten up my room a little, I will include a photo later.
