This is a great bar cart. The shelves hold up with a bunch of bottles on it. To be fair, we do not wheel it around. It just stays in one spot.

Perfect for limited space

This bar cart works well for small spaces or areas. I got this cart since I live in a 700 sq ft apartment and I needed something that would store all my liquor and equipment, as I barely have any counter space. As seen in the photo, it looks great, too. Was relatively easy to assemble as well. The only complaint I have is the wheels. I seriously considered taking them off as they can be annoying at times and get stuck easily. If it wasn’t for the wheels, I would’ve given the cart 5 stars. Still works great given how inexpensive it is.

Perfect for the Price!
Color: Greige, Size: 13"D x 23.7"W x 32.7"H
The bar cart was very easy to put together. I can be "mechanically challenged" and was able to do it myself LOL It's nice and sturdy, the wheels roll smooth when you move it. The size is perfect for the small wall I have it against. I have several bottles of liquor and bartending mixer set on top, and about 20 various glassware on the 2nd shelf. The bottom shelf is taller, and does let you stand larger bottles down there. The one racks will only for the smaller size, but does hold them well.
