Perfect for the space
Size: 8 Cube Shelf
I am so pleased with this organizer. My daughter needed more storage for her closet, and I came across this storage organizer. I like how sturdy it is, and it was quick to assemble. It is the perfect size for her closet. And it was not expensive at all. She even liked that it came in plain wood and with drawers to organize her belongings and spaces for bigger items in her closet that can be placed on the shelf cubbies. I will definitely recommend it!

Strong smelling bins
Size: 8 Cube Shelf, Size: 8 Cube Shelf
Amazing shelf and love that it’s solid wood, but the fabric bins smell so strongly. Even through the wood is not highly treated, I am wondering if the bin material is full of formaldehyde. I cannot find any information on materials of bins. I will be replacing them with natural rattan or woven grass.

Good Quality & Value - baskets included!
Size: 4 Cube Shelf, Size: 4 Cube Shelf
I bought this shelf as opposed to others because it was the best value considering it comes with baskets. Perfect shelf for a small space where I needed extra baby storage. I like the natural look but you could easily paint or stain it since it’s unfinished. Super quick to assemble and good quality pieces.

Genuine wood & easy assembly!!
Size: 8 Cube Shelf, Size: 8 Cube Shelf
This is a really nice genuine all wood storage unit! Everything needed to assemble it, was in the box. It came with simple instructions, the natural wood is beautiful and all the edges are very smooth. This was literally the easiest assembly ever, since everything lined up so perfectly! There were a couple of extra screws but I'd rather have extra versus being short. Yes, you can see the screw heads but a dab of wood putty is a quick fix. The handles on the bins are a nice clean classy touch, instead of a cheaper looking material pull. There were also 3M pads included. I used those to cover the flush screw heads and corners (on the bottom) to protect my wood floors. This works perfectly for storage for my gemstone jewelry shop on etsy. It keeps everything organized, within easy reach and all in one spot. And, of course, looks good doing so.
Will update on durability.

solid item, worth it.
Size: 9 Cube Shelf
solid wood, well designed and easy to put together. A few of the back pieces were bowed but thats what you get with wood and it all went together just fine, can't even tell. They are unfinished, but ready for stain or poly Its not often I am pleased with furniture off of Amazon but I will be ordering a few more of these.
