I love these shelves! I specifically wanted shelves that were very long and that would, when put together, span the length of my room. These fit the bill! Quality: I was very worried about finding something that would hold up a good amount of weight, knowing I wanted to books on these shelves above my head! And I also wanted something with a nice texture that would be easily whipped down for dust. Both these points were covered. I have hade these shelves for several months now and they have successfully held ip a decent bit of weight, is a true black cooler with wood grain detail, and has not faded in color with dusted and whipped down to be cleaned. These are great quality and with the price!

Great shelf for price. VERY easy to install. We put one side of screws of metal bracket in studs to make it sturdy & stable. This was KEY! Follow simple drawing dictions and you can’t go wrong! Was Leary about some bad reviews but we had no issues. Came quickly with no flaws. Looks great and is very light, but is stable when put into bracket correctly. Size is beautiful with the thickness & depth of upscale shelf. If you want a nice shelf that doesn’t break the bank- get it. This one worked well for us!
