Bar Cart Review
Size: Rustic Brown, Style: Standard
Easy and quick to assemble/put together. Happy with the look and how much it is able to hold. Yet it’s still small enough to fit in a corner of my apartment.

Great addition to our home
Model: Model B with Removable Tray
Putting together took a little time but instructions included were easy for me to follow. Putting the screws in for the shelves required a little work to get then started but nothing that I would say would be a problem to do. It is very sturdy and looks great in our room we are transforming into a hangout/bar area. I can't wait to get all my accessories in to add to it and display all my nice bottles I have. Great cart for the price.
