Tujurich 3-Tier Shelf
A 3-tier carbon steel shelf with 5-minute tool-free assembly.
Pros
- 100 lbs per shelf, 300 lbs total
- 5-minute assembly, no tools required
- Carbon steel with rust-resistant finish
- Compact 17.3 by 12.8 inch footprint
Cons
- Spec lists a 240-pound minimum weight
- No warranty term is stated
- No leveling feet stated
- Plastic connectors, not all metal
Detailed Review
Tujurich lists a 3-tier shelf at 17.3 by 12.8 by 28.9 inches in carbon steel with reinforced plastic connectors. The listing states 100 lbs per shelf for a 300-pound total, a rust-resistant finish, and assembly in 5 minutes with no tools. A contradiction appears: the spec table lists a minimum weight of 240 pounds against the 300-pound total in the bullets; we trust the bullets.
Who it's for: kitchens, pantries and bathrooms that want fast assembly in a compact unit. Who should skip it: anyone who wants a stated warranty, or leveling feet.
Its Office Score of 9.6/10 comes from performance 29/35, build 21/25, value 20/25, safety 5/10 and warranty 0/5: 75 of 100 points, placed on our 9.2 to 9.8 scale.

Detailed Review
The DUMOS unit is a 4-tier steel wire shelf, 13.4 inches deep, 23.3 inches wide and 47 inches high, with a heavy duty four-leg steel frame. Note the listing contradiction: the spec table lists both a 200 pound maximum and a 200 pound minimum, while the bullets state each shelf supports up to 200 lbs. The listing names bathrooms, garages, kitchens, laundry rooms and living rooms as rooms, with a lacquered black finish. The unit weighs 11.7 pounds, per the listing, so one person can move it between rooms.
Who it's for: wider storage spaces that need adjustable tiers. Who should skip it: anyone who wants a stated warranty, leveling feet, or a single clear capacity figure.

Detailed Review
Sakugi lists a 3-tier metal shelf at 18 by 12 by 30 inches in alloy steel with a powder-coated finish. The listing states 100 lbs per shelf, 4 adjustable leveling feet, and assembly with no tools. A small contradiction appears: the spec table lists 12.6 by 18.31 by 30.71 inches against the 18 by 12 by 30 inches in the title and bullets; we trust the title and bullets.
Who it's for: small rooms and tight areas that want the smallest unit here. Who should skip it: anyone who wants a stated warranty, or more than 3 tiers.

How we scored them
The Office Score weighs performance, build, value, safety and warranty; for storage shelves, safety means steady frames, leveling feet and stated weight capacities. None of these listings states a safety certification or a warranty term. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SINGAYE 5-Tier Shelf | 9.5 | 30 | 21 | 21 | 0 | 0 |
| DUMOS 4-Tier Shelf | 9.5 | 29 | 21 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best storage shelves under 30
Tiers and footprint
The SINGAYE unit gives 5 tiers in a narrow 10 by 16 inch footprint, 55 inches high, while the DUMOS unit gives 4 tiers in a wider 13.4 by 23.3 inch footprint, 47 inches high. Measure the space first, including the door width: the SINGAYE unit needs 16 inches, the DUMOS unit 23.3 inches, to move in. A narrow unit suits a closet wall; a wider unit suits a pantry or garage wall. The SINGAYE listing names bedrooms, closets, garages, kitchens and living rooms as rooms, while the DUMOS listing names bathrooms, garages, kitchens, laundry rooms and living rooms, so both cover the usual home storage spots.
Weight capacity
The SINGAYE unit lists a 600 pound maximum weight capacity, while the DUMOS listing states each shelf supports up to 200 lbs. Note the DUMOS contradiction: its spec table lists both a 200 pound maximum and a 200 pound minimum, so the per-shelf bullet figure is the one to plan around. Match the capacity to the load: books, canned goods and heavy tools need the higher figure. Spread heavy items across tiers rather than loading one tier, and keep the heaviest items low, since neither listing states a per-tier figure for the SINGAYE unit.
Adjustability and floors
The SINGAYE mesh tiers adjust up and down on a 1 inch basis, and the DUMOS tiers have adjustable height settings, so tall boxes and small jars can share one unit. The SINGAYE unit adds adjustable leveling feet for uneven floors, which the DUMOS listing does not state. See every bookshelf and file cabinet guide for more storage furniture.
Mesh tiers versus open wire
The SINGAYE unit uses mesh tiers, and its listing states the shelves are more densely arranged, with smaller gaps more suitable for the storage of items. That suits small items that could slip through wide wire gaps. The DUMOS unit is a wire shelf with adjustable tiers, and its listing describes a heavy duty four-leg steel frame that stays steady under canned goods or heavy tools. When the load is small items, the denser mesh has the edge; when the load is heavy goods, the steel frame matters more.
When a basic 3-tier shelf fits
The Sakugi and Tujurich picks are title-only listings: a 3-tier metal shelf and a 3-tier shelf with plastic connectors, with no dimensions, capacity or warranty stated. They suit a simple storage need where the exact size does not matter, but measure first when the space is tight. For the full storage range, see all office machines and storage guides.
Planning the load across tiers
Five tiers beat four when the load is many small items, since each tier holds a separate group: pantry goods on one tier, cleaning supplies on another, tools on a third. The SINGAYE unit gives five tiers at 10 inches deep, so each tier suits smaller items, while the DUMOS unit gives four tiers at 23.3 inches wide, so each tier holds wider boxes. Neither listing states a per-tier figure for the SINGAYE unit, and the DUMOS per-shelf figure needs the contradiction note above kept in mind. When the load is heavy, spread it across tiers and keep the heaviest items low, since a single overloaded tier is where a shelf fails first.
Setup Notes
- Measure the space first: the SINGAYE unit is 10 by 16 by 55 inches, the DUMOS unit 13.4 by 23.3 by 47 inches.
- Check the door width: 16 inches for the SINGAYE unit, 23.3 inches for the DUMOS unit.
- Plan tier heights around tall items; both full-data units adjust tiers.
- Check the weight capacity against the load: 600 pounds on the SINGAYE unit, 200 pounds per shelf on the DUMOS unit.
- Confirm no warranty is stated before ordering, since none of these listings states one.
Frequently Asked Questions
How tall are these storage shelves?
The SINGAYE unit is 55 inches high and the DUMOS unit is 47 inches high. The Sakugi and Tujurich listings state no dimensions, so check the listing before ordering either one.
How much weight can these shelves hold?
The SINGAYE unit lists a 600 pound maximum, and the DUMOS listing states each shelf supports up to 200 lbs, though its spec table lists both a 200 pound maximum and a 200 pound minimum.
Do these shelves adjust?
Yes, on the full-data picks. The SINGAYE mesh tiers adjust on a 1 inch basis, and the DUMOS tiers have adjustable height settings, so tall boxes and small jars can share one unit.
Which shelf fits a narrow closet?
The SINGAYE unit, at 10 inches deep and 16 inches wide, is the narrowest pick here and the one to check first for a closet wall. The DUMOS unit is 13.4 inches deep and 23.3 inches wide, so it needs a wider space.
What rooms do these shelves suit?
The SINGAYE listing names bedrooms, closets, garages, kitchens and living rooms, and the DUMOS listing names bathrooms, garages, kitchens, laundry rooms and living rooms.
Are these shelves freestanding?
Both full-data units are floor mount, per their listings, so they stand on the floor rather than hanging on a wall. The Sakugi and Tujurich listings state no mounting type.
