White subframe. Cannot be Used Alone. Expand The Modular Capability of The Bookshelf Without The Cost of Another Full Bookshelf Unit. (White)

Excellent product, good price. Holds all of my books without sagging or any problems.

Well packed and protected. Easy to follow instructions, assembly was quick and easy (did it by myself). Very sturdy and looks good in our home office. Would buy again.

Nice, heavy duty book case - shelves won't warp with lots of hardback books. Purchased with Subframe - it was all pretty easy to assemble and adding another subframe will be a breeze. Shelf height is fully adjustable. Had a little issue with Fed Ex delivering two of the three packages. Seller was extremely responsive at tracking down the missing package.

Shelf is perfect. I bought this shelf to hold Lego models. I have seen all of these displays of people using IKEA shelves for this purpose, but they are so expensive in comparison. This shelf is strong and looks great. The shelves are very strong and seem to support the weight perfectly. It is the perfect height and thickness, and has great stability once attached to the wall

Really looks like wood with a clean, fresh appearance, but much lighter. Fairly easy to assemble as well. Overall, happy with this purchase and that it met our expectations.
