As I write this, London is in the grip of one of its hottest days of the year so far, with amber heat-health warnings in place and the mercury pushing well into the thirties. Offices up and down the country are facing the same problem: desk fans on full blast, blinds drawn, and a workforce that's struggling to concentrate.
What's rarely mentioned in all this is the one piece of furniture every office worker has direct, hours-long contact with: their chair. If your team is still sitting in foam-padded or fabric-upholstered seating, they're fighting the heat from the moment they sit down. This is exactly where a mesh office chair earns its keep, and it's why the Ergohuman Elite G2, Mirus Elite G2 and Enjoy Elite G2 are built around breathable mesh rather than traditional padding.
The real cost of a hot office
Heat in the workplace isn't just an uncomfortable inconvenience, it has a measurable effect on output.
- Productivity falls sharply once temperatures climb. Research from Loughborough University's Environmental Ergonomics Research Centre, part of the international HEAT-SHIELD project, found that working at 35°C with 50% relative humidity results in an average 35% decrease in productivity throughout the workday, rising to a 76% reduction once conditions reach 40°C and 70% relative humidity. Most UK offices won't reach those extremes, but the trend is clear: the hotter it gets, the less work actually gets done.
- The vast majority of UK office workers already feel it. A nationwide survey by Workthere found that 89% of UK office workers lose productivity when the temperature isn't right, and just 16% said they were satisfied with their office temperature. The same research pinpointed the ideal UK office temperature at between 21–22°C, well below what most buildings reach during a heatwave.
- It's a recognised health and safety issue, not just a comfort one. There's no legally enforceable maximum workplace temperature in the UK, only an enforceable minimum, but the Health and Safety Executive is clear that employers have an ongoing duty to maintain "thermal comfort" and to risk-assess the workplace once people start to feel uncomfortably hot. HSE guidance notes that uncomfortably high temperatures impair concentration and decision-making and increase the likelihood of people cutting corners or skipping safety steps. Beyond discomfort, sustained heat can bring on fatigue, headaches and difficulty concentrating, the building blocks of an unproductive afternoon.
- It affects the wider economy, too. The Office for National Statistics now models the lost output ("GVA") caused by hot days across UK industries, treating sustained heat as a genuine drag on national productivity rather than a one-off nuisance. For employers, that's a useful reminder that thermal comfort isn't a perk, it's a productivity lever.
For a facilities manager or office fit-out contractor specifying furniture at scale, that's not a small consideration. A workforce that loses even a few percentage points of output on every warm day adds up to a meaningful cost over a year, and it's a cost that's almost entirely preventable with the right seating.
Why mesh outperforms foam and fabric in the heat
The reason is simple physics. Foam and fabric-padded chairs are, by design, insulators: they trap air, and with it, body heat and moisture, against the skin. After an hour or two in a warm office, that translates into a sticky back, a damp shirt, and constant fidgeting as the body tries to cool itself down.
A genuine mesh seat and backrest works the opposite way. The open weave allows air to pass continuously between the body and the chair, so heat dissipates instead of building up. Independent product comparisons consistently find that mesh seating runs noticeably cooler than an equivalent foam seat over the course of a working day, and that users report less thermal discomfort the longer they sit. In a non-air-conditioned office, or one where the air conditioning simply can't keep pace with a heatwave, that difference is the gap between staying focused and reaching for the fan every twenty minutes.
There's a hygiene benefit too. Mesh doesn't absorb sweat the way fabric does, which means it dries faster, holds fewer odours, and is considerably easier to keep clean in shared or hot-desked environments, an increasingly relevant point for any commercial office.
How the Elite G2 range is built for exactly this
All three chairs in our Elite G2 range share a high-performance mesh construction with breathable flex zones, but each suits a slightly different need.
Ergohuman Elite G2
The Ergohuman Elite G2 is our flagship model and the chair we'd recommend first for anyone serious about beating the heat. Its breathable mesh is paired with an automatic dynamic lumbar system, a twin-pivot synchro mechanism and fully adjustable 5D armrests, so you get all-day spinal support alongside constant airflow. It's certified to BS 5459-2:2000 and BS 5459-A2:2008 for 24-hour, multi-shift commercial use and safely supports users up to 150kg, which makes it as suitable for a round-the-clock control room as it is for a single home office. It also carries GREENGUARD Gold certification for low chemical emissions, an important specification point for any health-conscious workplace.
Mirus Elite G2
The Mirus Elite G2 brings the same breathable mesh and single-lever simplicity to a more streamlined, split-back design. It's an excellent option where desk space or budget is tighter but you still need genuine ergonomic adjustability and the cooling benefits of mesh.
Enjoy Elite G2
The Enjoy Elite G2 is our most accessible chair in the range, built around autoflex back and lumbar zones and the same intuitive single-lever control, without the premium price tag. It carries the same BS 5459 structural certification and Greenguard air quality certification as its siblings, so teams don't have to compromise on durability or breathability to stay within budget.
A note for fit-out contractors, designers and dealers
For commercial buyers specifying furniture for an office fit-out, all three Elite G2 chairs are certified for continuous, multi-shift, 24-hour commercial use under BS 5459, not just light domestic duty. That matters when summer temperatures put extra strain on cheaper materials: lower-grade foam can soften, sag or smell in sustained heat, while a properly engineered mesh chair holds its shape and breathability for years. Specifying mesh as standard, rather than as an upgrade, is a straightforward way to futureproof a fit-out against the warmer summers the UK has been experiencing in recent years.
Quick FAQs
Are mesh office chairs actually better in hot weather? Yes. Mesh allows continuous airflow between the body and the chair, so heat and moisture dissipate rather than building up, unlike foam or fabric, which trap both.
Can office temperature really affect productivity? Yes, and the effect is well documented. UK survey data shows the vast majority of office workers lose productivity when the temperature isn't right, and controlled studies show output can fall substantially once temperatures climb well above comfortable levels.
Is a mesh chair a good investment for a commercial office, not just a home setup? Absolutely. Mesh chairs like the Elite G2 range are certified for 24-hour, multi-shift commercial use, making them a durable, low-maintenance choice for fit-outs, dealerships and contractors specifying furniture at scale.
Stay cool, stay productive
Whichever model suits your space and budget, moving to a genuine mesh chair is one of the simplest changes you can make to keep a team comfortable and focused when the temperature climbs.
