I returned this. The fabric did not cover the tubes completely and created a gap that made this an unusable bookcase unless you have the fabric boxes.

You get what you pay for. I was foolish and didn't read the supplies closely, making the purchase based on the picture. It doesn't feel very sturdy when finished (wobbles, fabric is very thin). It also took me 20+ minutes to figure out how to assemble it before I started, because none of the parts were labeled. I had to count each (40 of one type, 24 of another, etc.) to determine what I had. The instructions are for all models. I also got the wrong model (ordered a four single row but got double rows). It will work for holding items when I put fabric cubes in, but it will not work nicely for books. The bottom of each row has spaced bars.

I love my cube storage shelf. It was easy to put together, and I organized all of my sewing stuff on it using baskets and clear storage bins

While it is a bit flimsy, it does the job for me and so far has been working pretty good! I’ve place quite a few books in the shelf’s and do not see any issues so far.

Flimsier than I’d hope it would be, but it’s very light and easy to move.
