Very good product! Gorgeous wood
These 4’ wide shelves are very nice. The wood is blond and gorgeous. I bought 2 sets. The hardware is very heavy duty iron piping!

Great when installed. Some problems
Style: 48inch 2 tier
The shelves are assembled and installed on my wall. I'm happy with them. They look great and are very sturdy. What prevents a 5-star rating? The instructions were poor. Not a huge deal as I was able to figure things out. The wall anchors that came with were cheap and (in my opinion) unusable. I went to Lowe's and bought some drywall anchors that were rated for 79 pounds and they worked well. During the install, I wasn't sure if I should attach the wall plates and assemble the shelves on the wall, or assemble everything and then attach it to the wall. Assembling before hanging was the way to go but it took two people. One other minor thing: The shelves are stained on one side an not the other. Since I have them high up on a wall, I'm looking at the unstained side. Yes, I can stain the unstained part, but it would be nice if they had just stained the top and bottom at the factory.

Beautiful Shelving Unit
Style: 48 inch 3 tier
The shelving unit is beautiful. It has not been hung yet, but I plan on using it to replace my entertainment center and hang my TV above it. I am so excited as the shelves matched perfectly to my furniture so I believe it will be a lovely addition to my living room and take up less space than the entertainment center does.
