A 9 a.m. call in a warm room is when you notice the chair, not the desk: your shirt sticks to the backrest and the seat feels damp by noon. The best office chair for keeping cool is the one that moves air around you instead of trapping it. We compared five seating picks by breathability, stated capacity, build, stated safety features and warranty, using only what each listing publishes. Mesh backs and fabric seats lead the list, a faux leather seat trails it, and one add-on pad cools a chair you already own.

Detailed Review

It states BIFMA certification and a Class 4 gas cylinder verified by SGS, a 300 lb maximum weight and a 1-year warranty against manufacturing defects.

What this listing states. BIFMA certification and a Class 4 gas cylinder verified by SGS are stated, so safety scores 7 of 10. 1-year warranty against manufacturing defects, stated.

Detailed Review
The Samyoung is a mesh lumbar support, 15.7 by 12 inches, with double-layer breathable mesh, adjustable elastic straps and two vertical straps that change the frame’s bend.

How we scored them
The Office Score weighs performance (breathability and stated capacity), build, value, safety and warranty. For a chair, safety means a stated BIFMA certification, gas lift class or weight capacity on the listing; the COLAMY states BIFMA and a Class 4 SGS lift, the Efomao and OLIXIS state SGS lifts, and the other two state no certification. Only the COLAMY states a warranty term. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| COLAMY Mesh Office Chair | 9.7 | 30 | 22 | 21 | 7 | 3 |
| Efomao Big and Tall Chair | 9.6 | 30 | 22 | 21 | 5 | 0 |
| DUMOS Mid Back Chair | 9.5 | 28 | 20 | 20 | 3 | 0 |
| OLIXIS Criss Cross Chair | 9.4 | 21 | 20 | 19 | 7 | 0 |
| Samyoung Mesh Lumbar Support | 9.4 | 23 | 19 | 20 | 2 | 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 office chair for keeping cool
Mesh or fabric beats PU leather
Airflow is the whole game here. The COLAMY and DUMOS use breathable mesh backs, and the Efomao wraps its big seat in breathable fabric instead of PU leather, which the listing calls out as staying ventilated. The OLIXIS goes the other way with a faux leather seat, the warmest back material in this set, and that is exactly why it scores lowest for cooling. If you run hot, put mesh or fabric at the top of the shortlist.
The seat matters as much as the back. The Efomao pairs its breathable fabric with pocket springs and foam so air moves under the cushion, while the Samyoung pad only cools the back and leaves the seat alone. If your current seat traps heat, the pad is a cheap experiment before a whole new chair; if the seat is the problem, no back pad will fix it.
Match the stated capacity to the user
Stated capacities run from 250 lb on the DUMOS to 400 lb on the Efomao, with the COLAMY and OLIXIS at 300 lb. Treat each figure as the maker’s claim and leave a margin rather than buying at the limit. A bigger user also sits deeper into the cushion, which cuts airflow, so capacity and cooling are linked more than they look.
| Chair | Back material | Capacity stated | Certification stated |
|---|---|---|---|
| COLAMY Mesh | Breathable mesh | 300 lb | BIFMA, SGS Class 4 |
| Efomao Big and Tall | Breathable fabric | 400 lb | SGS gas lift |
| DUMOS Mid Back | Breathable mesh | 250 lb | None |
| OLIXIS Criss Cross | Faux leather | 300 lb | SGS lift, BIFMA base |
Figures as stated in each listing’s spec table. On carpet the OLIXIS’s floor pads and the DUMOS’s silent casters matter too; our best ergonomic office chair for carpet guide compares rolling options.
Small room? Go armless and light
The OLIXIS is armless with no wheels and slides fully under a desk, and at 24.9 pounds it is easy to move. The DUMOS is the lightest here at 19.4 pounds with a mid back that does not block a small room’s airflow. For more small-space options see our best ergonomic office chair without arms guide.
Read the warranty line
Only the COLAMY states a warranty term: 1 year against manufacturing defects. The Efomao, DUMOS, OLIXIS and Samyoung listings state none, so with those four you are buying on the build and the stated certifications alone.
Assembly and first-day setup
None of these arrive ready to sit in. The Efomao lists 20 to 40 minutes of assembly with included tools, and the others list assembly required with instructions included. Lay the parts out on the floor first and check the casters against your floor type before you lift the finished chair onto the mat.
Plan the room while the boxes are open. The Efomao is 31 by 30 inches with a 135° recline that needs clearance behind it, while the OLIXIS’s armless, wheel-free frame slides fully under the desk when the day ends. Measure the desk height too: the DUMOS adjusts from 14.7 to 17.7 inches, and the Efomao lists a fixed 20 inch seat height.
When a lumbar pad beats a new chair
The Samyoung is the only pick here that is not a chair, and that is its point. If your chair fits well but the backrest runs warm, a 15.7 by 12 inch double-layer mesh pad with adjustable straps changes the airflow without a full replacement. It straps onto office chairs, armchairs, sofas and car seats, so the same pad can follow you from the desk to the car.
The trade is scope: it cools only the back. The seat, the arms and the room stay as warm as they were, and the pad is hand wash only. Treat it as a low-cost way to find out whether breathability solves your problem before spending on a full mesh chair.
Setup Notes
- Measure the desk and the room: the OLIXIS tucks fully under thanks to its armless, wheel-free design, while the Efomao measures 31 by 30 inches.
- Check assembly time: the Efomao lists 20 to 40 minutes with included tools, and the others list assembly required with instructions included.
- Match seat height to the desk: the DUMOS adjusts from 14.7 to 17.7 inches, and the Efomao lists a 20 inch seat height.
- Plan the floor: the OLIXIS uses floor pads and the DUMOS uses silent casters, both stated to protect hard floors.
