Mesh Office Chairs in Australia: How to Choose One That Keeps You Cool
The shirt stuck.
Picture a 36-degree Brisbane spare room in January, with a fan that only pushes the hot air around. You stand up to refill a glass, and your shirt peels off the seat with a small sound. The back of the chair was fine. The seat was the problem. It is a made-up scene, but a familiar one.
Mesh is a common question for Australian buyers, and for good reason. We're SIDIZ Australia, and we sell premium ergonomic office chairs. Mesh is one of the questions we hear from buyers in warm cities.
This guide explains where heat actually collects, what the different kinds of mesh do, and what to check before you pay. We checked each chair below against its live product page, and we have left out anything the page does not state.
Heat Collects Where You Sit, Not Where You Lean
What the Croatian seat studies measured
In 2012, Zoran Vlaović, Danijela Domljan and Ivica Grbac at the University of Zagreb measured temperature and moisture on five office chairs. Six people did their usual work while probes sat on and inside each seat.
The surface was always warmer than the inside of the seat. The moulded foam seats had the highest surface temperature and moisture of the types tested. Temperature and moisture also varied a lot between layers of padding and upholstery.
What 82 office workers reported
In 2025, Vlaović, Boris Iliev and Domljan published a larger study in the journal Applied Sciences. Eighty-two people rated thermal comfort on six chairs with different backrests, mesh or polyurethane foam, and different seat materials.
Warmth was stronger at the buttocks and thighs than at the back. Comfort of both seat and backrest affected overall thermal comfort, as did how humid the sitter felt.
Why this matters for an Australian summer
There is a catch. The 2025 study took place in air-conditioned workplaces, and the authors call for seasonal tests. The studies did not test a hot home.
The direction is still useful. Warmth was higher at the seat than at the back, and the one foam backrest scored warmer than the mesh backs. If the hottest part of you is the seat, a mesh back may solve only part of the problem.
What the studies cannot tell us
The 2012 study had six people. The 2025 study relied on questionnaires, not probes. Neither tested Australian summers, and neither tested every chair on the market.
So treat the findings as a pointer. They say where to look, not which brand wins. That is why the checks later in this guide ask you to test the chair yourself.
Mesh Comes in Several Forms
Mesh is a fabric woven or knitted to hold tension while letting air through. How much it helps depends on where it sits on the chair.
| Where mesh sits | What it does | What to check |
|---|---|---|
| Backrest only | Lets air reach your back | Does the lumbar pad still adjust? |
| Seat and back (full mesh) | Airflow under the thighs and behind the back | How firm does the seat feel at hour three? |
| Headrest only | Cooler contact for the neck | A small gain on a warm day |
| Mesh with a foam seat | Cool back, cushioned seat | The seat may still run warm |
Mesh back with a cushioned seat
This is the most common design. The T50 page lists a mesh back with a cushioned seat. It is in stock at $399 and ships in three to seven business days.
Full mesh
A full-mesh chair covers the seat as well. The T50 Air 2nd Generation is described as full-mesh. It is on pre-order at $489, with dispatch in sequence from early November.
Mesh with fabric or leather options
The T90 lists double Raschel mesh, Aquatex fabric or natural leather. It is on pre-order at $1,299, and leather finishes are made to order.
Run a Heat Test Before You Commit
You can learn more from two hours in a chair than from any spec sheet. If the seller allows a trial or you can visit a showroom, use the plan below.
| Time | What to do | What to note |
|---|---|---|
| Minute 1 | Press your palm on the seat and back | Does the surface feel cool or warm? |
| Minute 30 | Work as you normally would | Any dampness behind the thighs? |
| Hour 1 | Stand and sit down again | Does the seat edge or mesh press? |
| Hour 2 | Check your shirt and the backs of your legs | Is the damp patch bigger than on your old chair? |
Compare against your old chair
Run the same test on the chair you use now. The point is not whether the new chair is cool in absolute terms. It is whether it is cooler than the one you already have.
Test at your real room temperature
A showroom is air-conditioned. Your spare room may not be. If you can, test at home during the warmest part of the afternoon, because that is when the difference between chairs shows.
Mesh Behaves Differently Across Australian Climates
This section is reasoning, not data. It applies the studies above to places they did not test.
Humid north
In Queensland's humid summers, sweat does not evaporate quickly. A porous surface lets moisture move away from the body, while a non-porous surface such as vinyl holds it against you.
Hot, dry inland
In dry heat, sweat evaporates fast, so the main job of the chair is to avoid trapping heat. Open mesh helps. So does keeping the seat out of direct sun.
Cooler southern winters
In a cold Hobart or Melbourne room, a mesh chair can feel cool in the morning. A cushioned seat may be a better fit if the room is unheated. A jumper or a throw can fix a lot.
Nine Checks Before You Buy a Mesh Chair
Lumbar support is still adjustable
A mesh back can follow your spine, but it does not always support your lower back. Look for a lumbar pad that moves. The T50 Air 2nd Generation lists a 290 by 160 mm pad with 50 mm of height and 10 mm of depth adjustment.
The seat edge feels comfortable
The edge of a mesh seat is where you notice the frame. A rounded or waterfall edge is kinder behind the knees.
The mesh feels firm enough, not hard
Mesh feels different from foam. It supports with tension, not cushion. Sit for twenty minutes before you decide. If you like to sink in, mesh may not suit you.
The load rating covers the user
The T50 2nd Generation, T50 Air 2nd Generation, T90 and LINIE are 125 kg. The GX lists 115 kg. Check the number for your chair.
The warranty states what it covers
Our products carry a five-year limited warranty, and the newer models ask you to register. Read what it covers, and keep your order email.
Headrest and armrests suit your body
A mesh headrest is breathable, but it still has to sit where your head rests. The T50 2nd Generation lists a 310 mm wide Airflex mesh headrest with 55 mm of height and 55 degrees of angle adjustment. Check the page for the armrest adjustments.
Assembly and delivery
The T50 2nd Generation and T50 Air 2nd Generation arrive flat-packed. Each weighs about 17.6 kg built, and the packed box measures 720 by 690 by 500 mm. Check that you can carry that to the room it will live in.
Colour and clothing
Dark mesh can show lint, and light mesh can show dye transfer from new jeans. It is a small point, but a visible one.
You can try it first
Check the showroom page on sidiz.au for visiting details. If you cannot go, read the cancellation and return terms on the page before you pay.

Compact rooms
The LINIE is on pre-order at $389. It comes with a flex or mesh back, and we recommend it from about 150 cm. The page notes that some people at or below 160 cm may want a footrest.
The T50 2nd Generation, with a cushioned seat
The T50 2nd Generation is on pre-order at $449 with an Airflex mesh back. Its standard seat is cushioned fabric over moulded foam, and a mesh seat swap is offered, though availability may vary. It suits you if you want a mesh back with a more cushioned seat.
Mesh and Foam Trade Off Differently
| Mesh | Foam | |
|---|---|---|
| Heat and moisture | Lets air pass through | Can trap heat; moulded foam ran warmest in the 2012 study |
| Feel | Firm, supportive, springy | Soft, cushioned |
| Fit to the body | Follows the curve under tension | Moulded to a fixed shape |
| Upkeep | Vacuum and wipe | Wipe or spot-clean |
Support without the sink
A foam seat cushions you. A mesh seat holds you up on tension. Neither is better in every case. People who like a soft landing often prefer foam, and people who run hot often prefer mesh.
Wear over time
We could not find independent data on how long mesh lasts compared with foam, so we will not claim one outlasts the other. Ask what the warranty says about the mesh itself, and register the product when it arrives.
A mesh back is only as good as its frame
The mesh needs a frame that holds its tension and a back that follows your lumbar curve. Check the recline stops and the lumbar pad as well as the weave. The T50 2nd Generation lists five recline limits from 105 to 130 degrees.
Keep a Mesh Chair Clean and Cool
Vacuum the mesh with a soft brush attachment to lift dust. Wipe marks with a damp cloth and mild soap, and let it dry before you sit. Avoid sharp objects and pet claws, since a snag in woven mesh can spread.
Check the care notes on the product page for your chair. These steps are general practice, not a SIDIZ instruction.
When Mesh Is Not the Answer
Mesh is not better in every room. If your office is cold in winter, a foam seat may feel warmer. If you like a soft, sinking seat, mesh will feel firm. If you recline for long stretches, check that the mesh back still supports your shoulders.
Mesh also does not fix a poor fit. A hot chair that fits is still a better buy than a cool chair that does not. Our chair comparison page can help you check fit first.
Conclusion
Before you buy, press a hand onto the seat of any chair you try for a full minute. Then lean back and do the same on the backrest. Heat tells you what a spec sheet cannot.
Cool the seat, not just the back.

Frequently Asked Questions
Is mesh worth it in a hot Australian room?
The studies suggest mesh backrests run cooler than foam ones, and warmth concentrates more at the seat than the back. In a room that gets above 28 degrees, a full-mesh design is worth considering. Test it at your actual room temperature before you decide.
Does a mesh chair need lumbar support?
Yes. A mesh back follows your spine under tension, but it does not automatically land where your lower back curves. Look for a lumbar pad that moves in height and depth. Mesh without an adjustable pad is not better for your back than foam without one.
How long does mesh last compared to foam?
We could not find independent lifespan data for either. The warranty tells you what the brand covers, and the warranty period gives you a signal. Register your chair when it arrives and keep the order confirmation.
Can I claim a mesh chair on tax?
If you use it more than 50 percent for work and your employer did not supply it, you may claim the work-use share. Our office chair tax claim guide has a worked example, and an accountant can confirm your case.
What is the difference between the T50 and T50 Air 2nd Generation?
The T50 has a mesh back with a cushioned seat. The T50 Air 2nd Generation is described as full-mesh, covering both the back and the seat. Both share the same 290 by 160 mm lumbar pad. The T50 is in stock; the T50 Air 2nd Generation is on pre-order.
