Super cute
The shelf is cute, and super easy to set-up. Be careful with the screws, I stripped the magnet screw/hole a little bit. Street that I was a little weary on over-tightening the four corners of each shelf. Make sure you use the wall straps bc it will be a little wobbly.

Great shelf
Color: Greige, Size: 6 Tier(10.7 x 15 x 65.3 Inches), Color: Greige, Size: 6 Tier(10.7 x 15 x 65.3 Inches)
Very impressed with this! It was very easy for me to put together without any help. Very sturdy pieces and seems well made. Really can’t beat the quality for the price! The glass door on the bottom really dresses up this shelf. I will probably buy more of these for other rooms in my house.

Elegant shelf, easy assembly!
Color: White, Size: 4 Tier(10.7 x 15 x 40.8 Inches), Color: White, Size: 4 Tier(10.7 x 15 x 40.8 Inches)
I almost returned this because I didn’t think I could put it together, but the step by step picture instructions were easy to follow, and I assembled this in about 50 minutes, taking my time and also wiping down each wood piece so it would be ready to go once finished. This came packed very well and no parts were missing or messed up. It’s very elegant looking for being inexpensive and just what I needed budget wise and style wise. It is sturdy and beautiful and I like it very much and am glad I kept it, it is worth it!

Very easy to put together. Lightweight, great for what I was looking for. Holds a lot of books and perfect for me. I didn't want a heavy clunky bookcase.
