Affordable and useful

I purchased the solely to add some more organization to a closet so for my purpose, these worked very well. The main stays cubes are definitely not the same as the home and garden version that Walmart also sells so this would be the more affordable less durable version, but a solid choice depending on what use your purchasing it for.

Have many and then hold up very well.

I buy these for storage and the appearance. They look great, are sturdy and don't take up a lot of room. Holds a-lot of things and love using the tops as a space for decor. I have them in many different sizes and colors for different rooms. The price is good too compared to others out there.

Perfect for the need!!

This is perfect as a nightstand in my guest room. I attached the backing to the top cube and added two collapsible folding storage bins in the two cubes below, added an LED light in the empty cube and it is perfect. The height is also perfect, as the bed sits a little taller than many nightstands are suitable for. Thinking about getting another one for the other side.
