Why it’s great
The gap beside a refrigerator or washer is some of the most wasted space in a small kitchen, and this cart is built for it. It is only 5.91 inches deep and 17.76 inches wide, stands 50.79 inches tall, and holds six open mesh shelves on four swivel wheels, so it rolls out to reach spices, bottles, cans, or toiletries and rolls back in when you are done. The seller says it is made of metal with a compact mesh that does not shake, and the open mesh bottom keeps water from collecting. Buyers say it is easy to assemble, fits between counters and refrigerators, and holds small items and large spice containers. The things to check are stability and weight: some buyers call it wobbly, and the listing does not state a clear weight limit.
Bottom line
A practical, easy-to-assemble slim cart for a narrow gap and light loads, as long as you keep heavy items on the bottom shelves and accept that some buyers find it wobbly.
Best for
- A gap of at least 6 inches by 18 inches, such as between a refrigerator and a counter or beside a washer and dryer
- Spice bottles, sauces, canned goods, toiletries, and other light, small items
- Small kitchens, apartments, and laundry rooms with no pantry space
- Renters who want a rolling piece they can move without tools or wall mounting
- Anyone who also needs narrow storage in a bathroom or living room, since the seller lists several rooms
Who should skip this
- Anyone who needs to store heavy items, since the listing does not state a weight limit and the seller says to put more weight on the bottom shelf than the top
- Anyone whose gap is narrower than about 6 inches or shorter than 18 inches
- Anyone who wants a rock-solid tower on uneven floors, since some buyers call it wobbly
- Anyone who needs to be sure about the wheels, since buyers disagree on how well they roll and the listing does not clearly say they lock
Key features
- Black iron frame with plastic parts and six tiers, listed at 5.91 inches deep, 17.76 inches wide, and 50.79 inches tall, and weighing 10 pounds
- Four swivel wheels that the seller describes as easy-glide, for moving the cart in tight spaces
- Open mesh shelves and a mesh bottom that the seller says keep water from collecting, so the unit stays dry
- The seller says to place more weight on the bottom layer than the top to keep the cart stable
- The listing says each shelf is 8.86 inches high and suits spice bottles, toiletries, bath towels, and books
- Assembly hardware is included, with instructions and labeled parts; the seller says its support team will help within 24 hours if the cart arrives damaged, scratched, or missing parts
- Also sold in a 10 inch wide version, and the page links to warranty information rather than stating terms
- Listing check, weight limit: the page does not state a clear load rating. A safety note on the page mentions 75 pounds, but it describes that figure as implied from the construction rather than tested. Do not rely on it, and keep loads light
- Listing check, shelf height: six shelves at 8.86 inches each would add up to more than the 50.79 inch overall height, so treat the 8.86 inches as a rough clear height per shelf rather than an exact one, and measure your tallest bottles against it
- Listing check, size and wheels: the title calls it 6 inches wide, but the specs list 5.91 inches as the depth and 17.76 inches as the width. Plan for a footprint of about 6 by 18 inches. The comparison chart also ticks “lockable wheels,” while the main copy describes swivel wheels only, so do not assume the wheels lock
Performance and usability
- Amazon’s summary of buyer reviews says customers find the cart easy to assemble and like its capacity for small items and large spice containers
- Buyers say it fits well in various spaces, particularly between counters and refrigerators, and works for its intended purpose
- Opinions on stability are split: some buyers find it sturdy and good value, while others report it is wobbly and not worth the price
- Buyers disagree on how responsive the wheels are, so expect to test it on your floor
- The most-mentioned themes in the review summary are quality, assembly, sturdiness, functionality, and fit
- The seller’s safety note says to keep children from playing on the cart and to use caution on uneven surfaces to prevent tipping
- Individual reviews are behind a sign-in, so there is little detail on the wobble complaints, such as whether they relate to floors, wheels, or the six-tier height
Real world use cases
- Storing spices, oils, and sauces in the gap between the refrigerator and the wall
- Keeping canned goods and dry pantry staples in a small kitchen
- Holding detergent, cleaning supplies, and towels beside a washer and dryer
- Organizing toiletries and bath towels in a narrow bathroom corner
- Rolling it out as a mobile prep or auxiliary shelf, then tucking it away after cooking

Scorecard
| Category | Rating | Notes |
|---|---|---|
| Aesthetic & Form Factor | Medium | Plain black metal mesh that blends in, but is utilitarian rather than decorative |
| Space Efficiency | High | Six shelves in a footprint of about 6 by 18 inches, built for gaps beside appliances |
| Performance & Speed | Medium | Works well for small items, but buyers are split on wobble and wheel response |
| Ease of Cleaning & Maintenance | Medium | Open mesh drains and wipes, but the listing gives no care instructions and mesh can trap dust |
| Quietness | N/A | Static shelving; the page gives no noise information for the wheels |
| Build Quality & Durability | Medium | Metal frame, but reviews are split between sturdy and wobbly, and no load rating is given |
| Ease of Setup / Learning Curve | High | Buyers say it is easy to assemble, and hardware and labeled parts are included |
| Eco & Sustainability | Low | Iron and plastic with no recycled content or certification listed |
| Value / Price-to-Performance Ratio | Medium | Value price tier, but some buyers say it was not worth the price |
| Portability | High | Weighs 10 pounds and rolls on four swivel wheels |
What is in the box

- Four swivel wheels
- Assembly hardware and an instruction sheet with labeled parts
Final verdict
The ThreeHio six-tier cart is a practical, easy-to-assemble way to put an unused gap to work, and its 5.91 inch depth fits places most storage cannot. The caveats are practical: the listing gives no clear weight limit, buyers are split on stability and wheels, and the shelf height and size labels are inconsistent. Measure your gap, keep loads light and low, and it is a reasonable value pick for small items.
What to know before buying
Slim carts are easy to love and easy to overload, because a tall, narrow frame is less stable than a wide one. Measuring the gap and keeping loads light matters more than any feature.
Q: What matters in a slim rolling cart
A: Measure the gap’s width and depth first, plus the height of your tallest bottles. Then check for a stated weight limit, how the wheels work, and whether the cart comes with the hardware you need. Put heavy items on the bottom shelf, since a tall, narrow cart tips more easily.
Q: How it compares to alternatives
A: Wider rolling carts are steadier and hold more, while slim carts like this fit gaps nothing else will. Wall-mounted shelves free the floor but need drilling, and fixed narrow racks avoid wheels but cannot be moved out for access.
Q: Who this category is best for
A: Slim carts suit small kitchens, apartments, and laundry rooms where there is a narrow gap and no room for a pantry, and they suit renters who cannot drill into walls.
Q: Who it’s not ideal for
A: Skip this style if you need to store heavy items, if the floor is uneven or soft, or if you want a freestanding unit that never wobbles.
