Racing seat or task chair?

In the gaming chair vs office chair question, an ergonomic office chair is the better buy for most people who sit at a desk for hours. The Steelcase Series 1 costs £609.00 on Amazon UK at the time of writing (September 2026) and adds 60 mm of seat depth adjustment, which none of the gaming chairs in this comparison offers, plus 12 years of cover on its mechanisms and foam against 2 years for the £349.99 noblechairs Hero: £50.75 per year of warranty against £175.00.

A higher price does not buy a better fit. The noblechairs Hero costs £60.00 more than the Sihoo Doro C300 at £289.99, yet trades mesh for PU leather and a 3-year warranty for a 2-year one. Gaming chairs do win in three places: recline, head support and extreme sizes. The Corsair TC100 Relaxed reclines from 90° to 160°, against 23° of back inclination on the Steelcase Series 1, and Secretlab builds the Titan Evo in an XL size for users up to 205 cm and 180 kg.

What makes a chair ergonomic, according to the HSE and BS EN 1335?

An ergonomic chair adjusts to its user: UK workplace law asks for an adjustable seat height and backrest, and the British standard for office chairs adds seat depth, lumbar and armrest adjustment. The Schedule to the Health and Safety (Display Screen Equipment) Regulations 1992 says “the seat shall be adjustable in height” and “the seat back shall be adjustable in both height and tilt”, and that a footrest should be available to anyone who wants one.

The Health and Safety Executive's posture guidance turns that into three chair checks: the seat height should support the front and back of the thighs equally, the backrest should give good lower back support, and there should be a “gap of 2-3 cm between front of seat bottom and back of knee”. BS EN 1335-1:2020 sets the dimensions. Its Type A class of fully adjustable office chairs requires:

Adjustability has field evidence behind it. A 2003 study in the journal Spine by Amick and colleagues gave office workers either a highly adjustable chair with ergonomics training, training alone, or nothing until the study ended. After 12 months the chair-with-training group showed lower growth in musculoskeletal symptoms over the working day (P = 0.012); training alone did not (P = 0.461).

Are bucket seats and side bolsters bad for sitting at a desk?

Bucket seats are built to hold a driver in place through corners, and their side bolsters shrink the flat part of the seat that a desk worker actually sits on. Tom's Hardware's best gaming chairs guide, updated on 25 August 2026, says many gaming chairs “look like they belong in cars”, with “bucket seats, winged backs, and relatively stiff construction with firm, dense padding”, and that the best gaming chair “isn't necessarily one that's marketed as a gaming chair”.

• noblechairs Hero:35 cm of seat width at the point of contact and 52 cm in total, per noblechairs' figures published by Tom's Hardware.
• Corsair TC100 Relaxed:36 cm between the seat bolsters, measured by PCGamesN, which warned that the bolsters “have minimal padding”.
• Office chairs: Steelcase lists a 440 mm seat width for the Steelcase Series 1 and Sihoo 52 cm for the Sihoo Doro C300 Pro V2. BS EN 1335-1 sets a 400 mm minimum.

Brands measure seat width differently, so these figures are not a compliance check. The newest gaming chairs are flattening the bucket: Secretlab gives the Titan Evo Regular 47 cm of seat between its sides, and Razer fits an “ultra-wide” seat base to the Razer Iskur V2 NewGen.

The noblechairs Hero costs £349.99 on Amazon UK at the time of writing (September 2026), sold by Overclockers UK. Its side dial sets lumbar firmness inside the backrest, which Tom's Hardware said made the lumbar pillow optional, though the same review called the chair “on the stiff side”. The noblechairs Hero suits buyers who want the racing look and fit a fixed 50 cm seat.

Is a lumbar pillow as good as adjustable lumbar support?

No: a loose or strapped lumbar pillow has to be repositioned by hand and can slide out of place, while built-in lumbar support stays where it was set. The DSE Regulations ask for a backrest adjustable in height, and BS EN 1335-1 Type A chairs must move their lumbar support through at least 70 mm, between 170 mm and 300 mm above the seat.

• Pillows:Tom's Hardware found the noblechairs Hero's lumbar pillow “just sits there with no attachments”, and PCGamesN wished the Corsair TC100 Relaxed's strap-on cushion were “slightly deeper”.
• Built-in on gaming chairs:the better gaming chairs have moved on. Secretlab fits the Titan Evo with a 4-way L-ADAPT lumbar system, and Razer's HyperFlex lumbar on the Razer Iskur V2 NewGen adjusts up, down, in and out, according to Razer.
• Office chairs: the Steelcase Series 1 has height-adjustable lumbar support as standard. The Sihoo Doro C300 uses a self-adaptive lumbar pad that moves with the back, plus 60 mm of backrest height adjustment in four positions, according to Sihoo.

The fair conclusion is narrower than “gaming chairs have bad lumbar support”. Budget gaming chairs rely on pillows, premium ones build support in, and every office chair here builds it in.

Do gaming chairs have seat depth adjustment and 4D armrests?

Many gaming chairs now have 4D armrests, but none of the five gaming chairs in this comparison lists seat depth adjustment, the setting that matches a chair to thigh length. The noblechairs Hero and Corsair TC100 Relaxed have a fixed 50 cm seat, and Secretlab fixes the Titan Evo at 48 cm, 49 cm or 50 cm depending on size.

Seat depth decides whether the HSE's 2-3 cm knee gap is achievable. A seat that is too deep for a short thigh either presses behind the knee or forces the sitter forward, away from the backrest and its lumbar support. The Steelcase Series 1 slides from 420 mm to 480 mm (60 mm of travel) and the Sihoo Doro C300 Pro V2 from 43 cm to 47 cm (40 mm), against the 70 mm that BS EN 1335-1 asks of Type A chairs.

Armrests matter because the HSE wants the keyboard just below elbow height with relaxed shoulders. The Steelcase Series 1, noblechairs Hero, Secretlab Titan Evo and Razer Iskur V2 NewGen have 4D armrests; the Corsair TC100 Relaxed has 2D armrests. Tom's Hardware found the noblechairs Hero's armrests “barely padded”.

The Steelcase Series 1 costs £609.00 on Amazon UK at the time of writing (September 2026), sold and dispatched by Amazon, which matches the £609 price on Steelcase's own UK store. The Steelcase Series 1 suits anyone who works at a desk for most of the day and wants one chair for a decade or more.

Does PU leather peel, and is mesh cooler than leatherette?

PU leather wears faster and traps more heat than mesh or fabric, and gaming chair brands now market their own upholstery against it. Tom's Hardware's buying advice is blunt: “Faux leather won't last as long, but real leather is pricier. Mesh or fabric is more breathable, but can be harder to clean.”

• Durability claims:Razer describes the Gen-2 EPU leather on the Razer Iskur V2 NewGen as “more durable than regular PU leather” and its armrest tops as “highly resistant to peeling and cracking”.
• Warranty cover:Secretlab's UK warranty FAQ states that “aesthetic defects and damage due to misuse of product are not covered”. Steelcase covers the Steelcase Series 1's surface materials for 5 years, and the Amazon UK listing rates its wool-blend seat fabric at 120,000 Martindale abrasion cycles.
• Heat:Tom's Hardware found the fabric Razer Iskur V2 X “much more breathable than faux leather” and more comfortable in hotter weather.

Racing looks do not require PU leather: the noblechairs Hero TX puts the same design in textile fabric, rated to 150 kg, for £349.99 on Amazon UK (September 2026). Mesh office chairs go further, with an open weave across both seat and back.

The Sihoo Doro C300 costs £289.99 on Amazon UK at the time of writing (September 2026), sold on Amazon by SIHOOUK, and Sihoo states that it meets EN 1335. Tech Advisor's Simon Jary, reviewing the Sihoo Doro C300 and C300 Pro V2 in April 2026, called both “genuinely comfortable for long hours of use”. The Sihoo Doro C300 suits home workers on a budget who run warm; buyers with short or long thighs should step up to a chair with seat depth adjustment.

When is a gaming chair the better buy?

A gaming chair is the better buy for people who recline to play with a controller, want a pillow behind the head, want the racing look, or need a size that office chairs rarely come in. Recline is the clearest gap:

• Gaming chairs:Corsair TC100 Relaxed 90° to 160° (Corsair), Secretlab Titan Evo 85° to 165° (Secretlab), Razer Iskur V2 NewGen up to 152° (Razer), noblechairs Hero up to 135° (Tom's Hardware and the Amazon UK listing; noblechairs' US site lists 125°).
• Office chairs: Steelcase Series 1 23° of back inclination (Steelcase), Sihoo Doro C300 stops at 110°, 120° and 130°, Sihoo Doro C300 Pro V2 at 105°, 120° and 135° (Sihoo).

Tom's Hardware notes that controller players may prefer “a less active position” than keyboard-and-mouse players. For couch-style play in front of a TV, a deep recline with a neck pillow is the right tool, and the best TV for PS5 and Xbox Series X sets the screen side of that setup. Size is the other win: Secretlab sells the Titan Evo in Small, Regular and XL, and the XL takes users up to 205 cm and 180 kg.

The Corsair TC100 Relaxed costs £199.99 on Amazon UK at the time of writing (September 2026), sold and dispatched by Amazon. PCGamesN called it “a great value gaming chair to kick back and relax in”, while criticising the 2D armrests and a neck pillow fixed at one height. The Corsair TC100 Relaxed suits console and PC players who lounge more than they type, pairing well with a machine from the best gaming PCs in the UK.

Which chairs suit tall, short and heavy users?

Short users are best served by office chairs, heavy users by specialist office chairs, and very tall users by the largest gaming chairs. A dash means the maker does not publish the figure.

• Short users:the noblechairs Hero's lowest seat height of 480 mm sits 80 mm above the 400 mm floor of the BS EN 1335-1 Type A range, so shorter users will need a footrest. The Steelcase Series 1 drops to 410 mm.
• Heavy users: FlexiSpot rates the FlexiSpot ErgoX Pro (£369.99 on Amazon UK, September 2026) to 250 kg, with seat depth adjustment and 7D armrests. Corsair limits the Corsair TC100 Relaxed to 120 kg.
• Tall users: the Secretlab Titan Evo XL is rated to 205 cm, 15 cm beyond the Steelcase Series 1.

How long do gaming chair and office chair warranties last?

The 12-year terms from Steelcase and Herman Miller run four to six times as long as the 2- and 3-year terms on most gaming chairs here, which makes the dearer chair cheaper per year of cover. Tom's Hardware notes that Herman Miller's warranty is 12 years, while “the average gaming chair usually carries a 5 year warranty at most”, and more often 2 to 3 years.

The Steelcase Series 1 costs £259.01 more than the noblechairs Hero but £124.25 less per year of cover (£50.75 against £175.00). The Secretlab Titan Evo is the best-covered gaming chair here, at £93.80 per year once owners complete Secretlab's extended warranty programme, which lifts cover from 3 to 5 years. The Sihoo Doro C300 Pro V2 fares worst: £529.99 buys the same 3 years as the £289.99 Sihoo Doro C300.

What does the gaming chair premium buy?

On a raw count of adjustments a good gaming chair matches an office chair, but the premium does not buy seat depth adjustment, breathable upholstery or a long warranty. The checklist, drawn from the DSE Schedule and BS EN 1335-1, covers seat height, seat depth, recline lock, recline tension, lumbar height, lumbar depth, and armrest height, width, depth and pivot.

The noblechairs Hero is the cheapest chair per adjustment, at £43.75, but the count hides what each chair cannot do. Three price-matched pairs show the trade:

• noblechairs Hero over Sihoo Doro C300 (+£60.00): buys 25° more recline range, a fourth armrest direction and manual lumbar and tension controls. It gives up backrest height adjustment, an adjustable headrest, mesh upholstery and a year of warranty.
• Sihoo Doro C300 over Corsair TC100 Relaxed (+£90.00): buys two more adjustments, 30 kg more load rating, mesh and a third year of warranty. The Corsair TC100 Relaxed keeps 50° more recline.
• Steelcase Series 1 over Secretlab Titan Evo Regular (+£140): buys 60 mm of seat depth travel, 12 years of mechanism cover against 3 to 5, and a breathable mesh back. It gives up 57° of recline range, the magnetic head pillow and the XL size option.

Adjustability only pays if it is used. A 2019 University of Derby study in Applied Ergonomics found that office chairs offered 5.39 adjustable functions on average, but their users knew 2.51 and used 1.86; 73% had used two or fewer and 10% had used none.

Which chair should each type of buyer choose?

Most desk workers should choose an office chair, and people who lounge in front of a TV should choose a gaming chair. Prices are Amazon UK at the time of writing (September 2026).

How should an office chair be set up?

An office chair should be set up from the floor upwards in five steps, following the HSE's posture guidance:

1. Seat height: the thighs are supported equally front and back and the keyboard sits just below elbow height; a footrest makes up the difference for shorter users.
2. Seat depth: a 2-3 cm gap between the seat front and the back of the knee.
3. Lumbar: the support sits in the small of the back, between 170 mm and 300 mm above the seat on a BS EN 1335-1 Type A chair.
4. Armrests: high enough that the shoulders stay relaxed, low enough to slide under the desk.
5. Recline tension: the backrest follows the sitter without pushing forward.

Desk height matters as much as the chair, and the best standing desks in the UK lists which frames reach which heights. Buyers who want to move more while working should read the best walking pads in the UK, and a chair that rolls freely needs cables kept off the floor, covered in how to hide desk cables.

What should UK buyers check before ordering a chair?

UK buyers should check who sells the chair, how heavy the box is and whether an employer should be paying for it.

• Seller: at the time of writing, Amazon sells and dispatches the Steelcase Series 1 and Corsair TC100 Relaxed, Overclockers UK sells the noblechairs Hero, and SIHOOUK sells both Sihoo chairs. The seller handles returns.
• Consumer Rights Act 2015: a faulty chair can be rejected for a full refund within 30 days, and a fault that appears within six months is presumed present at delivery.
• Weight:Tom's Hardware lists the noblechairs Hero at 33 kg, and Sihoo ships the Sihoo Doro C300 Pro V2 in two boxes of 18.38 kg and 17.96 kg.
• Employers: the DSE Regulations apply to workers who use screens daily for continuous periods of an hour or more, and the HSE says employers must assess those workstations, including for home working.

Verdict: gaming chair or office chair?

An ergonomic office chair is the better buy for most people. The Steelcase Series 1 at £609.00 on Amazon UK (September 2026) has 60 mm of seat depth travel, 4D armrests, height-adjustable lumbar support and a 12-year warranty on mechanisms and foam, at £50.75 per year of cover. The Sihoo Doro C300 at £289.99 brings mesh and a 3-year warranty for £60.00 less than a noblechairs Hero. Gaming chairs earn their place for lounging: the Corsair TC100 Relaxed at £199.99 reclines to 160°, and the noblechairs Hero at £349.99 is the pick for buyers set on the racing look.
