# Best Office Chair 2026: The Measurements Nobody Publishes

Every chair on this page is ergonomic, according to its own listing, and almost none of them publish the figures that would let you check. Four measurements decide whether a chair suits a person: the seat height range, the rated load, the density of the seat foam, and how far the lumbar support and the backrest actually move. Between them, the ten chairs here publish most of them once each.

The SIHOO M18, with 15,877 ratings, is the only chair that gives a seat height — 43cm to 51cm — and an overall height. The SONGMICS executive states a 150kg capacity and adds, in brackets, that it is self-declared, alongside a base it says was supplier-tested to 1,136kg of static pressure. The Yaheetech is the only listing that names a foam grade: 28D. The Durrafy M01 measures its own lumbar support, 8cm of vertical travel and 3cm horizontal, and the Durrafy M03 is the only chair that publishes a recline angle, 90 to 120 degrees. The CASTLOVE quantifies the one thing buyers actually feel: a 14cm thick seat.

Against those, six of the ten chairs give no capacity at all, and the ones that do often bury the figure in the title rather than the specification table — 136 KG on the Keratee, 150kg on the Durrafy, 330 lb on the SIHOO, in pounds on a UK listing. The word ergonomic sells the chair; the measurement is what tells you whether you can sit in it for eight hours. This ranking is ordered on the measurements, and the price to get them is usually the difference between £60 and £130.

## The ranking

### 1. SIHOO M18 Ergonomic Office Chair, Adjustable Lumbar and Headrest, 330 lb

- Price: £129.94 | Amazon rating: 4.3 from 15,877 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/sihoo-m18-ergonomic
- Buy on Amazon: https://www.amazon.co.uk/dp/B07GNDDNMW?tag=ranked10-21

15,877 ratings, a 330 lb capacity and the only listing here that publishes a seat height range: 43cm to 51cm.

The most reviewed office chair collected here by a factor of forty: 15,877 ratings averaging 4.3 stars, with 65 per cent five-star and 6 per cent one-star. It is a mesh-backed chair with 2D armrests, adjustable lumbar and headrest support, a tilt lock and five adjustment points, for £129.94 — the most expensive chair in this ranking.

It is first because of one line in its specification table that no other chair here writes: the dimensions. Overall height 110 to 125cm, seat height 43 to 51cm. That is the number that decides whether a chair suits a person and a desk, and it is missing from every other listing on this page, where you are left to guess from photographs. The 330 lb capacity is in the title, which is about 150kg — the same figure the SONGMICS executive chair claims, but in pounds on a UK listing.

The seat is W-shaped with a waterfall front edge, the standard design for taking pressure off the backs of the thighs, and the mesh back is the reason to choose this over the PU chairs here: it does not get warm. What you pay for the sample and the specification is £129.94, £44 more than the next mesh chair down the list. If your desk is an unusual height or you are tall, that premium buys a measurement rather than a badge.

Pros: 15,877 ratings: the largest sample in this ranking by far; The only listing here publishing seat height (43-51cm) and overall height; 330 lb capacity stated in the title; 2D armrests, tilt lock and five adjustment points; Mesh back with a W-shaped seat and waterfall edge
Cons: £129.94, the most expensive chair in this ranking; 6 per cent of its 15,877 ratings are one-star; Capacity given in pounds rather than kilograms; 2D armrests, where cheaper chairs here offer more lumbar travel

### 2. Keratee Ergonomic Office Chair with Adjustable Lumbar and Flip-Up Arms

- Price: £79.99 | Amazon rating: 4.6 from 132 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/keratee-ergonomic-mesh
- Buy on Amazon: https://www.amazon.co.uk/dp/B0GTQTFWY6?tag=ranked10-21

The best-rated chair in the ranking at 4.6 stars from 132 ratings — and a 136kg capacity that appears in the title only.

A mesh-backed chair with a padded seat, adjustable lumbar support behind the mesh, a pneumatic height lift and arms that flip up so it slides under a desk. It costs £79.99 and carries 4.6 stars from 132 ratings with 81 per cent five-star and 4 per cent one-star — the best-rated chair collected in this ranking.

Its capacity is the interesting omission. The title says 136 KG; the specification table says nothing about load at all, and neither does any bullet. On a page where the two chairs that do publish a capacity both attach a caveat to it — one self-declared, one in pounds — the Keratee puts a number in the title and stops. The 136kg is plausible for the class; there is simply nothing in the listing to check it against.

What the reviews support is assembly and value: easy to put together, sturdy and good value for money are the recurring themes, and 4.6 stars from 132 ratings is the strongest average here. If you want the best-reviewed chair rather than the most specified one, this is it — with the caveat that you are trusting a rating rather than a measurement.

Pros: 4.6 stars from 132 ratings: the best average in this ranking; 81 per cent five-star with only 4 per cent one-star; 136kg capacity stated in the title; Flip-up arms so it slides under a desk; Breathable mesh back with a high-density padded seat
Cons: Capacity appears only in the title, not in the specification; No seat height or overall height published; 132 ratings: a small sample next to the big sellers here; No warranty stated in the listing

### 3. SONGMICS Executive Office Chair with High Back, PU Leather, OBG22BUK

- Price: £85.99 | Amazon rating: 4.3 from 3,872 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/songmics-executive-pu
- Buy on Amazon: https://www.amazon.co.uk/dp/B0787PL2PV?tag=ranked10-21

A 150kg capacity the listing calls self-declared, a base tested to 1,136kg, and a two-year warranty on an £85.99 PU executive chair.

A PU-leather executive chair with high-density foam, an adjustable backrest, a headrest and height adjustment, for £85.99. It carries 4.3 stars from 3,872 ratings — the second-largest sample in this ranking — with 66 per cent five-star and 7 per cent one-star, and it ranks 8th in Amazon's desk chair category.

Its specification table is the most interesting on the page because of two lines. The first is the base: the listing says the five-star base passed a supplier-tested static pressure test of 1,136kg for one minute without breaking. The second is the capacity: a maximum support of 150kg, with the words self-declared in brackets beside it — an admission that no external standard certified the figure, which is more honesty about load than any other chair here offers.

It also states a two-year manufacturer warranty, the longest on this page alongside the Vinsetto's six months and the SIHOO's silence. What you trade for the PU finish is heat: a leather-look chair does not breathe like mesh, which is why people who sit all day usually end up in a mesh chair. For £85.99 with 3,872 ratings behind it, this is the value executive option.

Pros: 4.3 stars from 3,872 ratings, the second-largest sample here; A base supplier-tested to 1,136kg of static pressure; 150kg capacity, described in the listing as self-declared; Two-year manufacturer warranty, the longest stated here; PU executive finish with high-density foam and a headrest
Cons: PU finish does not breathe like mesh; 7 per cent of its 3,872 ratings are one-star; The 150kg capacity is self-declared rather than certified; No seat height range published

### 4. CASTLOVE Fabric Office Chair with 14cm Thick Cushion, Linen, Grey

- Price: £109.99 | Amazon rating: 4.4 from 332 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/castlove-fabric-14cm
- Buy on Amazon: https://www.amazon.co.uk/dp/B0D7V92Q1J?tag=ranked10-21

The only fabric chair here, with a 14cm thick seat cushion — the one measurable comfort claim in the ranking.

The only fabric chair in this ranking, and the one with a measured comfort claim: a 14cm thick high-density foam seat cushion under a linen cover rather than PU leather, with a high back, head support, flip-up arms and swivel, for £109.99 with 4.4 stars from 332 ratings.

Fourteen centimetres is the sort of figure this category usually avoids: most listings say high-density foam and stop there. The material matters as much. The listing's own argument for linen over leather is airflow, and it is the same argument the mesh chairs make — which is why PU is the wrong choice for anyone who sits for six hours a day. A fabric cushion holds less heat than a leather-look one, and it does not squeak against clothing.

The flip-up arms tuck the chair under a table, with the listing claiming a square metre of floor space back, and the reviews are consistent about comfort up to the shoulders. What it does not publish is a capacity or a seat height range, which is the gap the SIHOO above fills — and part of the reason that one costs more.

Pros: A 14cm thick high-density foam seat, the only measured cushion here; Linen fabric cover, which breathes better than PU; Flip-up arms that the listing says free up 1㎡ of floor; 4.4 stars from 332 ratings, 72 per cent five-star; High back with head support and swivel
Cons: No capacity or seat height range published; £109.99: the second-most expensive chair in this ranking; 4 per cent of its 332 ratings are one-star; Ranked 54th in desk chairs, behind the leaders here

### 5. Youhauchair Office Chair, Ergonomic Desk Chair with Flip-Up Armrests

- Price: £89.98 | Amazon rating: 4.4 from 767 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/youhauchair-flip-up-arms
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CT21TBVZ?tag=ranked10-21

Flip-up arms, a tilt lock and 767 ratings at 4.4 stars for £89.98 — with no capacity figure published anywhere.

A mesh chair with padded flip-up armrests, adjustable lumbar support, a tilt lock, 360-degree swivel and pneumatic height adjustment, for £89.98 with 4.4 stars from 767 ratings — 69 per cent five-star and 3 per cent one-star.

The listing shows how much the word ergonomic covers. The bullets promise support for the back, the elbows and the posture; the specification table lists adjustability, armrests, reclining and space saving as special features; and nowhere in either does it publish a capacity, a seat height or the depth of the lumbar travel. Three chairs here do give at least one of those figures — the SIHOO gives seat height, the Durrafy gives lumbar travel in centimetres, the SONGMICS gives a capacity with a self-declared caveat — and the rest describe the shape of the support instead of its range.

What the reviews confirm is the practical side: assembly in about ten minutes, one buyer comparing it to adult Lego, and comfort through long sessions. At £90 it sits between the £52.99 BareTay and the £129.94 SIHOO, with a bigger sample than either at that price. Buy it for the flip-up arms and the tilt lock; do not expect the listing to tell you whether it fits your desk.

Pros: 4.4 stars from 767 ratings, 69 per cent five-star; Flip-up padded armrests and a tilt lock; Breathable high-density mesh back; Pneumatic height adjustment and 360-degree swivel; Buyers report ten-minute assembly
Cons: No capacity, seat height or lumbar range published; 3 per cent of its 767 ratings are one-star; No warranty stated in the listing; Ranked 35th in desk chairs, well behind the leaders here

### 6. Yaheetech Ergonomic High Back Office Chair with Lumbar Support, 28D Foam

- Price: £69.99 | Amazon rating: 4.3 from 827 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/yaheetech-28d-high-back
- Buy on Amazon: https://www.amazon.co.uk/dp/B0B9BGVRW1?tag=ranked10-21

The one listing here that publishes a foam density — 28D — for £69.99, with a movable lumbar pillow and a rocking function.

A high-back mesh chair with an adjustable headrest, retractable padded armrests, a movable lumbar pillow, a rocking function and height adjustment, for £69.99. It carries 4.3 stars from 827 ratings and holds 3rd place in Amazon's desk chair category, the highest category rank collected on this page.

The line worth reading in its listing is the foam: 28D high density, stated by grade. Density is what decides whether a seat cushions you or bottoms out after a year, and it is the specification this category almost never gives — the CASTLOVE above gives centimetres of thickness, which is a different thing, and every other chair says high density and stops. 28D is mid-range furniture foam, honest for the price and a real answer rather than a phrase.

The other practical feature is the lumbar pillow: movable rather than fixed, so it sits where your back wants it, and the reviews describe it holding up over long sessions. At £69.99 with 827 ratings, a third-place category rank and a published material grade, this chair has the best combination of evidence and specification here.

Pros: 3rd in Amazon's desk chair category, the highest rank collected here; The only listing that publishes a foam density: 28D; 4.3 stars from 827 ratings; Movable lumbar pillow and a rocking function; Adjustable headrest and retractable padded armrests
Cons: 7 per cent of its 827 ratings are one-star; Mesh back over a foam seat, so the seat is the warm part; No capacity figure published; No warranty stated

### 7. Durrafy Office Chair with 4D Lumbar Support, 150kg Load, Folding Arms

- Price: £61.76 | Amazon rating: 4.3 from 402 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/durrafy-4d-lumbar
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CG956ZKM?tag=ranked10-21

The only listing here that measures its lumbar support: 8cm of travel up and down, 3cm forwards and back, on a 150kg-rated chair for £61.76.

A mesh chair with a 150kg load rating, a back cushion that lifts, 90-degree folding armrests and what the listing calls 4D lumbar support, for £61.76 with 4.3 stars from 402 ratings.

The lumbar claim is why it appears here at all. Four dimensions is a marketing term — most 4D labels on chairs describe armrest movement — but this listing then does what almost nobody does and states the travel: the cushion adjusts 8cm up and down and 3cm forwards and backwards. That is a measurement you can hold against your own back, and it is the only quantified lumbar adjustment in this ranking, where the rest say adjustable lumbar and leave it there.

The 150kg rating is in the title and appears in the bullets; the specification table does not carry it, which is the same pattern as the Keratee's 136kg. What the reviews support is stability and quietness — one buyer notes it wheels around noiselessly and reclines well for the price. At £61.76 it is the best value among the mesh chairs here that state a capacity.

Pros: Lumbar travel stated: 8cm up and down, 3cm forwards and back; 150kg load rating, matching the highest capacity claimed here; 90-degree folding armrests for storage; 4.3 stars from 402 ratings; £61.76: the cheapest mesh chair here with a stated capacity
Cons: The 150kg rating is in the title, not the specification table; 5 per cent of its 402 ratings are one-star; No seat height range published; No warranty stated

### 8. BareTay Office Chair with 5cm Adjustable Lumbar and Headrest, Flip-Up Arms

- Price: £52.99 | Amazon rating: 4.4 from 186 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/baretay-5cm-lumbar
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CW67V22H?tag=ranked10-21

The cheapest chair here with a measured lumbar adjustment — 5cm of travel — plus a headrest and flip-up arms, for £52.99.

A mesh chair with a 5cm adjustable lumbar support, a Y-shaped frame, an adjustable headrest, padded flip-up armrests and height adjustment, for £52.99 with 4.4 stars from 186 ratings, ranked 13th in Amazon's desk chair category.

The 5cm is the number that earns it a place above the cheaper Vinsetto: it tells you the lumbar cushion moves, and by how much, where most listings in this price band show a photograph of a lumbar bump and let you assume it is fixed. It is half the travel of the Durrafy at £61.76 and half the price of the CASTLOVE at £109.99, which makes it the cheapest way to buy a chair whose support can be positioned.

The headrest is the other inclusion that matters at this price, since neck support is usually the first thing dropped in a budget chair. Reviews describe it as comfortable and better than expected for the money. What it does not give you is a capacity, a seat height range or a warranty — and at £52.99 the frame is lighter than the SIHOO's at more than twice the price, which is the trade when the specification is this thin.

Pros: Measured lumbar adjustment: 5cm of travel; Adjustable headrest at a budget price; Padded flip-up armrests; 4.4 stars from 186 ratings, 69 per cent five-star; Ranked 13th in Amazon's desk chair category
Cons: No capacity, seat height or warranty published; 4 per cent of its 186 ratings are one-star; A lighter frame than the chairs above it; Mesh seat rather than a deep foam cushion

### 9. Vinsetto Ergonomic Office Chair, Armless Swivel with Mesh Back

- Price: £37.99 | Amazon rating: 4.3 from 470 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/vinsetto-armless-mesh
- Buy on Amazon: https://www.amazon.co.uk/dp/B089GDN72J?tag=ranked10-21

The cheapest chair in the ranking at £37.99 — armless, with a published 85-97cm height range and a six-month warranty.

An armless mesh chair with a 6cm padded seat, a height range of 85cm to 97cm and a six-month warranty against manufacturing defects, for £37.99 with 4.3 stars from 470 ratings.

Two things separate it from the other budget entries. It publishes its height range — 85 to 97cm, the measurement that decides whether a chair matches a desk — and it is the only chair here whose stated warranty is shorter than a year, which is worth knowing rather than complaining about at the price. The armless design is the other choice: it saves width in small rooms and lets the chair tuck under a desk, at the cost of somewhere to rest your elbows.

The seat is 6cm of foam, thin against the CASTLOVE's 14cm, and with 8 per cent one-star ratings it is the second-weakest record among the cheaper chairs here. For £37.99 it is the least expensive way into a swivel chair with a mesh back, and the reviews describe straightforward assembly and reasonable comfort. If you want the cheapest chair here that still publishes a measurement, this is it.

Pros: £37.99: the cheapest chair in this ranking; Height range published: 85cm to 97cm; Six-month warranty against manufacturing defects; Armless design saves width and tucks under a desk; 4.3 stars from 470 ratings
Cons: Six months of warranty, the shortest here; A 6cm seat against 14cm on the CASTLOVE; 8 per cent of its 470 ratings are one-star; No armrests at all, which some buyers will miss

### 10. Durrafy Office Chair with 90-120 Degree Recline and Foldable Armrests

- Price: £59.54 | Amazon rating: 4.2 from 83 ratings
- Full review: https://www.ranked10.co.uk/home-office/best-office-chair/durrafy-90-120-recline
- Buy on Amazon: https://www.amazon.co.uk/dp/B0G2H15YDC?tag=ranked10-21

The only chair here that publishes a recline angle: 90° to 120°, on a mesh chair with S-shaped support and flip-up arms.

A mesh chair with an S-shaped backrest, a 90-to-120-degree recline, three-layer padded armrests that fold up through 90 degrees and a pressure-relieving seat cushion, for £59.54 with 4.2 stars from 83 ratings.

The recline angle is the specification worth having, and it is the only one published in this ranking. Recline is what turns a desk chair into somewhere you can sit for an hour without working, and the range matters: 120 degrees is a genuine resting position, where a chair that tilts a few degrees is really just a desk chair with a wobbly back. Combined with fold-up arms, it is the budget pick here for anyone who games or watches things at a desk.

The cushion is described as high-density with optimal firmness, which is the phrase this category uses instead of a number, and the reviews come from two very different buyers: one bought it for a husband and calls it comfortable and well made, another for a child starting school. Eighty-three ratings is a thin sample for a £59.54 chair, and the listing gives no capacity — which is the gap between it and the Durrafy M01, with a 150kg rating and 402 ratings for £2.22 more.

Pros: The only published recline angle here: 90 to 120 degrees; Three-layer padded armrests that fold up through 90 degrees; S-shaped backrest with a pressure-relief cushion; 4.2 stars from 83 ratings; £59.54: the cheapest chair here with a recline
Cons: Only 83 ratings: the thinnest sample here; No capacity figure published; The cushion is described by adjective, not by density; Ranked 14th in desk chairs

## Verdict

What we would buy. If your desk or your height is unusual, the SIHOO M18 at £129.94 is the only chair here that lets you check before buying, and it carries 15,877 ratings at 4.3 stars. For the best-reviewed chair at a sensible price, the Keratee at £79.99 has the strongest average here, 4.6 stars from 132 ratings, provided you accept that its 136kg capacity lives in the title rather than the specification. If you want a leather-look executive chair, the SONGMICS at £85.99 is the value pick with a 3,872-rating record, a two-year warranty and the most candid capacity claim on the page. And for a home office where the chair has to tuck away, the BareTay at £52.99 gives you a measured 5cm lumbar adjustment and a headrest for the least money.

What none of them tell you. Six chairs publish no load figure, so the fastest way to judge a budget chair is the warranty: the Vinsetto at £37.99 offers six months, the SONGMICS two years, and many of the rest say nothing at all. Material matters more than any adjective on the page: mesh and linen breathe, PU leather does not, and a chair you sit in for six hours will feel the difference long before the foam wears out. Two practical notes from the listings themselves: assembly takes about ten minutes on the chairs whose buyers mention it, and if you want a chair to rest back in rather than work in, the recline angle is the figure to look for — only one listing here gives it. Everything on this page comes from the Amazon listings, collected on 11 September 2026.
