Take pictures of product pieces in the carton. Assemble where you have room to lay each piece out.
Size: 8 cube, Size: 8 cube
This is a great product, and easy to assemble. The directions were straightforward. Only snag was getting pieces to line up, but able to figure it out. Good tools included.

Cute storage shelf.
Size: 12 cube
This is particle board, as expected for the price. Instructions were easy to follow. I assembled it alone but there was one step that would have been easier with 2 people. I have a better Allen wrench attachment than the one included and it saved my fingers a lot of pain. It's cute when assembled. The openings are 10.5x10.5x11 inches so 11x11x11 inch baskets don't fit but you can find 10.5 inch baskets that work. It's very sturdy and the way it's constructed, the shelves shouldn't ever droop. It's a good value for the money. It's perfect for my sewing room.

Smaller than expected.
Size: 8 cube
The directions were complicated with only image directions. One person can put this together. It took me about an hour. The item is smaller than I expected. The image is misleading. Definitely not waist high for an adult. More like thigh height. Guess I should have paid more attention to the measurements instead of the image. It looks nice when assembled. For the price I expected something taller.
