Must have for at home workers!
I bought this divider because I work from home and wanted to have a professional and neutral background for video conferencing. There were other dividers that I contemplated purchasing because of the variety of colors but ultimately decided to go with this divider because of prime shipping. I noticed in the reviews of other dividers on Amazon a lot of people talked about cracks. I noticed a few cracks on mine but they are small and minimal in appearance so it does not bother me (see pictures). Overall, it came in great shape. I love the color of the divider. I was concerned it would come solid brown based on the pictures but it is more rustic, which I love. The dividers are tall and long so it covers a great amount of space. The hinges go either way which is also a plus. I will say it seems slightly unstable on carpet but it would only move if bumped into so that is not much of a concern. Most likely would be more sturdy on solid/ hardwood floors. Overall, I am super happy with my purchase. Definitely worth the price with fast 2 day prime shipping and no assembly needed.

Eye pleasing shelves with the ability to hold weight
Color: Light Brown, Size: 4
Great set of 4 wood floating shelves. I used these to hold precon decks and other commander decks for magic the gathering cards. Though they are on the smaller size, they still fit up to 4 commander boxes side by side and and withhold double that if I stack the boxes. I am very impressed by the quality and how much weight each shelf can hold. The brackets to hang them make the shelves even more sturdy. The shelves are very pleasing on the eyes and the wood color is very natural. The shelves were simple to hang by one person. They look very stunning and of great value. They hold all kinds of items and function perfect as a shelf and look wonderful as a form/type of wall decoration even without items on the shelves. Overall I’m very happy with this purchase and I will be buying more of these shelves soon.

Great shelves
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
These are cute and easy to install. They were the perfect size for the location. I did use other drywall mounts to make sure they were more likely to stay in but after I installed they feel sturdy and reliable.
