Floating Shelves
Color: White, Size: 15.7 Inches, Color: White, Size: 15.7 Inches
I purchased a set of white floating shelves for my bedroom a couple months back, and I must say, they have definitely added a touch of modern elegance to the space. The installation process was surprisingly simple and straightforward, making it a breeze to set up the shelves exactly where I wanted them. The package came with all the necessary hardware, including sturdy brackets and screws, ensuring a hassle-free setup experience. I will say that the wall anchors included are not the best quality and I used a third party set. The sleek and minimalistic design of these floating shelves instantly caught my eye, and I couldn't be happier with how they complement the overall decor of my room. The clean lines and the bright white finish pop with the walls, providing a chic and uncluttered display area for my decorative items, and cherished keepsakes. They truly elevate the aesthetic appeal of any room and create an illusion of more space, which is always a bonus. However, one aspect that did disappoint me slightly was the visibility of the screws underneath the shelves. While the overall appearance is sleek and sophisticated, this minor flaw hinders the shelves from achieving a truly seamless "floating" effect. I understand that the screws are essential for stability and security, but I wish the manufacturer had found a way to conceal them better, perhaps with a cleverly designed cover or by providing white screw caps. Despite this minor setback, I still appreciate the functionality and attractiveness of these floating shelves. They have undoubtedly decluttered my living space and allowed me to proudly showcase my favorite items. I have received compliments from friends and family on how the shelves enhance the ambiance of the room. In conclusion, if you are seeking easy-to-install, stylish white floating shelves to add a contemporary touch to your home, these shelves are an excellent choice. Their seamless installation and sleek appearance make them a delightful addition to any room. Although the visible screws detract slightly from the overall aesthetic, the shelves' overall performance and elegance more than make up for it.

Good Product
Color: White, Size: 15.7 Inches
Well designed and sturdy. Though not real wood I think they will last. It took me an hour to install the first shelf. That was all on me. I was slow measuring and placing the shelf bracket. I kept dropping the level and doing other crazy things. But the second and third shelves were easy after I learned what I was doing. Even though the screws, etc were provided I used Easy Anchor drywall anchors rated at 50 pounds. Just drill it in the sheet rock then screw the screw through the hole in the bracket until it clicks, (you have to listen). That means the ends of the plastic anchor flips out like a toggle bolt. Continue tightening the screw and that is it. Think I read somewhere that the board wobbles. These were tight as could be and no wobble. I did learn to only "tighten" just one end of the bracket sort of snug and let it hang. Then raise it to level and mark the other holes with a pencil. Don't put the other screws in until you are sure you can see the plastic anchors' holes though the bracket. Then place and tighten all the screws. The only negative I saw was that they could have sent the same or similar anchors that I have. But they didn't call me. Guess they didn't have my number.
