Pleased!
Size: 24 Inch, Color: Rustic Brown, Size: 24 Inch, Color: Rustic Brown
I purchased two of these shelves. Both were received but one was a busted up return from another customer that didn’t get taken out of circulation. Parts were missing and damaged. Returned that for a replacement. It came in perfect. These are easy to put together, minus the pesky stickers that took a lot of patience, Goo Gone, and scraping to get off. I love the 2-tone of the black metal and brown wooden shelves and extra nice touch the middle shelf folds down.

Perfect shelf for the office
Size: 24 Inch, Color: Rustic Brown, Size: 24 Inch, Color: Rustic Brown
When we bought our house it came with an office space and this little wall space in between the cabinets lol. We had no idea what to do with it BUT our monitors took up so much room that we couldn't put anything on the desk really. Then we got the idea of a floating shelf and well this was perfect! Matches and really looks like it came with the house haha. It has held up and now I get my office supplies and can look at pics!
