Great shelf for price!
Color: Natural Oak, Number Of Shelves: 1, Size: 35.4 inches, Color: Natural Oak, Number Of Shelves: 1, Size: 35.4 inches
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!

Nice shelves. Minor defect in one of mine.

Sturdy and easy to hang. Look nice. One of the set screw holes was off by 1-1/2” so I had to drill a new one, that wasn’t ideal.

Nice looking but bad quality and defects
Color: White, Number Of Shelves: 2, Size: 60 inches, Color: White, Number Of Shelves: 2, Size: 60 inches
Shelves look nice, but not great quality and one of my shelves came crooked (installed it perfectly level). Also has defects around the edges. Already installed so don’t want to rip off wall and return, but would like if they sent a couple new replacements at no charge. Keep you posted if that happens.
