Great shelves, poor instructions
Size: 16in 2P, Color: White
We bought these corner shelves for our son’s nursery, and the quality of the shelves themselves is great. We have plants on the shelves and no scratches even with sliding them on and off weekly to water them. The pots are very big and the plants are pretty heavy so they are holding up quite well. However, the instructions for hanging them were not very clear, and it took us several tries (and some wall damage) before we got them up correctly. We eventually found better guidance from another source. Once installed, though, they look great and feel sturdy.

Love them!
Size: 9/10/12in(3P), Color: Oak, Size: 9/10/12in(3P), Color: Oak
A little difficult to install but only because my corner must not be exactly a 90° angle and that’s not the shelves fault, that’s a me problem! It had multiple parts for different mounting options and even included a level tool for each shelf! They are built very well and super sturdy. I love that I was able to choose the distance between them that fit my plants and the aesthetic. I have 3 good size plants on each of the bottom shelves and it holds them with ease. I also was able to run a grow light cord up through the back and it’s nearly invisible. I’m definitely going to buy more and fill as many corners in my home with more plants!!!

Good quality corner shelf
Size: 10in, Color: White
Good quality corner shelf with included wall anchors for drywall or masonry walls. The paint finish is smooth and has a slight shine. I needed a corner shelf to relocate my modem to a higher location. This is perfect !

Elegant and Sturdy - A Perfect Addition to My Home
Size: 7in, Color: White
Elegant and Sturdy - A Perfect Addition to My Home I recently purchased the **7-inch White Solid Oak Wood Floating Corner Shelf** and I am absolutely delighted with it! This shelf has not only met but exceeded my expectations in both functionality and style. **Build Quality and Design:** The first thing that struck me was the quality of the oak wood. It's solid and feels very durable, which gives me confidence that it can hold my items securely. The white finish is flawless, providing a clean, modern look that complements my home decor beautifully. Additionally, the round edges are a nice touch, adding an element of sophistication and safety, especially in a household with children. **Installation Ease:** Installation was a breeze. The shelf came with all the necessary hardware and clear instructions. I was able to mount it in my desired corner with minimal effort. It sits flush against the wall, giving it a seamless appearance. **Versatility:** Despite its compact size, this shelf is incredibly versatile. I've used it to display a small plant and a couple of framed photos, which it holds perfectly. It's also ideal for small speakers, trinkets, or even as a bedside shelf for essentials. **Space-Saving Design:** For anyone looking to maximize space, especially in smaller rooms or apartments, this shelf is a fantastic solution. It turns an empty corner into a functional, stylish display area without taking up floor space. **Overall Experience:** I am thoroughly impressed with this floating corner shelf. It's not just a shelf; it's a piece of decor that enhances the look of my room. I highly recommend it to anyone looking for a high-quality, stylish, and functional shelving solution.
