Walk barefoot across a dark driveway in January and you learn quickly that surfaces in the Australian sun store serious heat. Chairs are no different. If you have ever hovered over an alfresco seat at a midday BBQ, you have probably asked the obvious question: do metal chairs get hot enough to matter when you are choosing outdoor furniture?
The short answer is yes — but the full answer is more useful. This explainer covers the simple physics of why some chairs feel hotter than others, how the common seat materials compare, and what helps if your outdoor area cops full sun. If new seating is on the cards, our outdoor chairs and benches collection is the place to start.
Do metal chairs get hot? The short answer
Yes. Any chair left in full sun on a hot day will warm up, but bare metal is the material most likely to become uncomfortable to sit on. That is not because metal somehow attracts heat. Two properties do the work: how much sunlight the surface absorbs, and how quickly the material passes that heat into your skin.
The good news is that the same physics hands you easy fixes. Shade, colour choice and the right seat surface change the experience completely — usually more than the frame material does.
Why metal feels hotter than timber
Metal is an excellent conductor. When you sit on hot aluminium or steel, heat moves from the surface into your skin quickly, so it feels intense straight away. Timber is a poor conductor. A teak seat at the same temperature releases its heat slowly, which is why it reads as warm rather than burning.
That slow-release quality is why timber chairs are a popular pick for exposed, all-day-sun decks. The San Remo Chair ($457) is hand made from FSC-certified plantation teak, built to stay outside all year, and its timber seat stays milder to the touch than bare metal in the same spot.
Conduction cuts both ways, though. Metal sheds its heat just as quickly once the sun is off it, so a metal chair dragged into shade is often comfortable again within minutes, while thick timber holds its warmth longer into the evening.
How common chair materials compare on a hot afternoon
| Seat material | In full sun | Worth knowing |
|---|---|---|
| Bare metal (aluminium, steel) | Heats fastest; can be uncomfortable on bare skin | Cools just as fast once shaded; light colours help enormously |
| Timber (teak, kwila) | Warms slowly; usually still sittable | Feels milder because it conducts heat into you slowly |
| Sling and mesh fabric | Stays closest to air temperature | Open weave sheds heat and lets air move through the seat |
| Moulded resin and plastic | Middle of the road | Dark colours can still get very warm |
| Cushioned seats | Fabric surface warms, but insulates you from the frame | Cushion colour matters more than the frame beneath it |
Notice the pattern: comfort is decided by the surface your skin actually touches, not the frame alone. A metal-framed chair with a sling or cushioned seat behaves nothing like a solid metal bench.
Colour and finish change the equation
Dark surfaces absorb more of the sun's energy than light ones — the same reason a black car bonnet cooks while a white one stays far milder. A charcoal chair in any material runs hotter in full sun than the identical chair in white or pale grey. Matte, textured finishes also feel slightly kinder than smooth polished ones, because less surface contacts your skin at once.
If your outdoor area faces west and collects the harsh late-afternoon sun — a familiar story in Perth and Adelaide — lean light: pale frames, light slings, and cushions in sandy or neutral tones.
Shade beats material — and the rest of the decision
No material choice beats simply keeping the sun off the seat. Under a roof, pergola or umbrella, every chair — metal included — settles much closer to the air temperature, and the hot-seat question largely disappears. That matters most for north- and west-facing areas, which collect sun through the hottest part of an Australian afternoon.
Touch temperature is only one side of the ledger, too. How a material weathers — rust, fading, greying timber — is the other, and we cover that side in detail in our guide to aluminium, wicker and timber-look outdoor furniture materials. Read this post for how a chair feels in February; read that one for how it will look in five years.
Keeping seats comfortable through summer
Padded slings are the sleeper pick. The Callala Bay Chair ($169) pairs a white frame with a padded grey Textaline sling, so air moves through the seat and the pale frame reflects sun rather than soaking it up.
Folding chairs earn their keep too. The Teak Folding Chair ($149) folds flat to live behind a door or in the shed between gatherings, which means it spends the hottest hours under cover instead of baking on the deck.
Whatever you own, a cushion or folded towel thrown over a sun-soaked seat makes it usable straight away. And test before the kids sit down — the back of your hand on the seat for a few seconds tells you everything you need to know.
Metal chairs and summer heat — frequently asked questions
Do metal chairs get too hot to sit on in summer?
In full sun on a hot day, yes — a bare metal seat can become genuinely uncomfortable, especially on bare skin. In shade, the same chair usually sits close to air temperature and is perfectly fine. Colour is the multiplier: dark metal heats up noticeably more than light.
Why do metal chairs feel hotter than timber ones?
Because metal conducts heat into your skin far faster than timber does. Two seats can reach a similar temperature in the sun, but the metal one delivers its heat quickly while timber releases it slowly, so the metal chair feels hotter.
What colour outdoor chairs stay coolest in the sun?
Light colours — white, off-white and pale grey — stay coolest because they reflect more sunlight than they absorb. Charcoal and black run hottest in any material, which is worth remembering for uncovered north- or west-facing areas.
Do sling chairs stay cooler than solid seats?
Generally, yes. An open-weave sling holds very little heat and lets air pass through the seat, so it sheds warmth quickly — and it dries fast after wet swimmers, which is a handy bonus.
How do I cool down a hot chair quickly?
Move it into shade — metal in particular loses its heat within minutes once the sun is off it. If moving it is not an option, a light-coloured towel or a cushion over the seat does the job immediately.
