Perfect for tight spaces and surprisingly sturdy!
Color: White, Size: 6 Tier(13 inches)
I am beyond impressed with this 6-tier storage cart. I was looking for something to maximize the vertical space in a very narrow gap, and this fits like it was custom-made. What I love: Quality & Durability: The carbon steel frame feels very stable, and the safety stops on the drawers are a game-changer—you don’t have to worry about the baskets falling out when you pull them. Design & Aesthetics: The wood top gives it a premium look that blends nicely with my decor, unlike all-plastic utility carts. The white finish is clean and bright. Ease of Use: Assembly was straightforward, and it rolls smoothly even when fully loaded. I also appreciate the 6 side hooks for hanging smaller items. Versatility: The drainage holes in the baskets make it great for the bathroom or laundry room, but it’s cute enough for a craft room or kitchen too. If you have a small space that needs serious organization, this is definitely worth the investment. It’s functional, high-quality, and looks great!

A great product!
Color: Black, Size: 6 Tier(8 inches), Color: Black, Size: 6 Tier(8 inches)
This storage cart really maximizes the space going up. This rolling cart is taller than me; I have 8-foot-tall doors, and you can see from my picture how tall this is. It is lightweight, rolls smoothly, is easy to assemble, and is a great value. You can place heavier or taller shampoo bottles on the shelves; they are pretty steady and not loose. The way this is built, the shelves are sturdy (they have 2 metal poles underneath giving them support). They also don't slide all the way out, so you don't have to worry about pulling it out too far and having things fall. This is a really great product, and I plan to use it in my master bathroom for all the extra stuff we have.

Great value!
Color: Ink Black, Size: 2 pack
Really sturdy and a great value for the money. Almost idiot proof when putting it together, too. The drawing is very specific, and everything is really well marked and numbered. This isn’t fine furniture, but it really is a great value for the money!
