After reading mixed reviews I was on the fence on getting these. I am glad that I took a chance. They are just what I needed to add storage to my closet and these are working out so well. They are fairly sturdy and each cubby has a storage bin on it.and is holding up great. I love the versatility of these - you don’t have to connect them all together and as seen in the photo, I ended up using four cubes on my dresser, I store my paperback books on them with no problems.Overall, I would definitely recommend these to anyone looking to add shelving.
