Really nice shelves well-made
Size: 30 Inch, Color: Walnut, Size: 30 Inch, Color: Walnut
I recently installed a set of floating wooden shelves above my kitchen sink, and they have completely transformed the space. The natural wood grain adds warmth and character, making my kitchen feel more open and inviting. The shelves are sturdy and well-made, supporting everything from dishware to small plants and decorative items without any sagging.
Installation was straightforward, with the included hardware making it easy to mount them securely. I was pleasantly surprised by how well they hold weight while maintaining a sleek, minimalistic look. The floating design gives a clean, uncluttered aesthetic, which is exactly what I was looking for.
Functionally, they’ve made a huge difference. I can now keep everyday essentials like mugs and spices within easy reach while freeing up valuable counter space. They’re also a great alternative to upper cabinets, preventing the area above my sink from feeling closed in.
Overall, these floating wooden shelves are both practical and stylish. Whether you’re looking to add storage or just enhance your kitchen’s design, they’re a fantastic option. I highly recommend them for anyone wanting a simple yet impactful upgrade to their space!

Look nice, not sturdy or supportive
Size: 17 Inch, Color: Dark Blue
The color and thickness of the shelf is great. Very easy to install. But the wall mount portion is cheaply made and doesn’t support the shelf as well as it should. Once mounted the shelf leans forward and isn’t sturdy. After mounting, I found my items had slid off end up on the floor.

The color is beautiful
Size: 17 Inch, Color: Dark Blue
These are beautiful! I bought them for my Grandsons Baseball room. We haven’t put them up yet. They will be a great addition to his red, white, and blue baseball room!

Beautiful, sturdy shelves — perfect for any room!
Size: 15.6 inch, Color: White, Size: 15.6 inch, Color: White
These 16-inch solid wood floating shelves exceeded my expectations. The quality of the wood is excellent — thick, smooth, and very sturdy. They were easy to install, and all the hardware was included. Once mounted, they feel secure and can hold a good amount of weight without sagging.
I love how they add a clean, modern touch to the room. I’ve used them to display small framed photos, books, and decor items in my living room, and they look fantastic. The small ledge is a nice feature too — it keeps things from sliding off easily.
Great for any space — bedroom, kitchen, hallway — and they’re both functional and stylish. Highly recommended!

They look as pictured. The white is nice. These are sturdy and easy to hang. I was worried because I have not had luck with hanging shelves in the past but these were great. Would definitely recommend.
