Sturdy
Size: 5.9"D, Color: Rustic White + Honey Brown
Works great, rolls well. Well put together, pieces fit, not lopsided, does not feel like it will shake apart in a second. Fits all the laundry detergent bottles I need, although I don’t use the jumbo sizes.
It is antique white, looks a bit distressed; while I like it, it may not fit everyone’s decor so take a good look at the picture.

Perfect cart Perfect fit !!
Size: 5.9"D, Color: Rustic White + Honey Brown, Size: 5.9"D, Color: Rustic White + Honey Brown
Put this cart together a few days ago. It took me, alone, about an hour. I’d say this cart is extremely well made!! Good to follow the instructions. Made assembly very easy. The frame and wheels are very stable and rolls very smoothly. Holds a fair amount of my bathroom products. I did consciously not attempt to make the cart hold more than it should although it’s very strong. It fits perfectly in the space between vanity and wall. I was going to put a piece of marble on the stained wood top but the finish is nice enough that I decided to appreciate the warm wood finish. Definitely recommend this item!!

Not Incredibly Stable
Size: 5.9"D, Color: Rustic White + Honey Brown
The storage cart was fairly easy to put together and looks nice. It's one of few that I've found to fit such a narrow space. Wheels roll well, but only move forward and backward. The cart will tip over if not fit in a small space that forces it to hold position. Works well for my space, but giving a 4 star rating due to that fact it will tip over easily.

great way to contain things for easy access
Size: 7.9"D, Color: Rustic White + Honey Brown, Size: 7.9"D, Color: Rustic White + Honey Brown
This was a great little storage cart. I picked it because of its size I had a very specific area it needed to be fit. I appreciate that it's very close to counter height. This worked well for a certain area in the kitchen. It looks nice. I like that it's on sturdy Wheels.
My husband put it together the night before Thanksgiving lol.
It was a little bit complicated for my brain to process at the moment because of how much I had going on. But once you sit down to do it it's really not too bad.
I also really appreciate that the shelves are adjustable. This is a great option from using counter space or floor space for things I need quick easy access.
I use mine for storing dog supplements treats and the bottom fits a couple of gallon jugs for my distilled water and another for vinegar.
Ideally I'd love it if there was one side with an option to enclose so I could flip it around when guests come over. Not a huge deal breaker I'll think of something because I understand the intention of this was to slide it in between two things. Mine is not oriented that way. But it's still attractive and useful.
