It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

The snap to put them together.

Color: Coal Black

This came in handy in the foyer. I didn’t want to see the door from my couch. I must be weak found it hard to snap them together. I kept 2 my daughter took the other 2.

I have 2!

Color: Coal Black

My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.

Simple, easy, and strong

Size: 16 Inch, Color: White

Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great
