This shortlist compares Desktronic SitOne and SitPro, IKEA JÄRVFJÄLLET and the Apex Comfort Resolute Mesh Chair. They provide distinct comparison points for adjustment, guarantee and published capacity. All were presented below £500 on the UK pages checked for this update, but live prices and variants can change. Published features do not establish a market-wide winner.
This is a researched buying guide, not a hands-on chair test. Comfort, pressure distribution and support are personal, and we have not independently assessed either chair over a working day. The header is a manufacturer-supplied promotional image from Desktronic’s Awin creative library. It depicts the SitPro chair family alongside a HomePro desk and is not evidence of hands-on testing.

How we built the shortlist #
We used official UK pages available on 22 September 2026 and prioritised named adjustments, published user limits, warranty or guarantee, and returns. We excluded subjective comfort and durability claims. Desktronic is prominent because its two models cover different adjustment levels and Home Desk Lab has an affiliate relationship with the company; IKEA and Apex Comfort provide additional comparisons from their official UK pages.
Quick comparison #
| Chair | Published adjustments | Recline information | Published buying terms | Best reason to compare |
|---|---|---|---|---|
| SitOne | Six adjustment points | Four recline positions | Three-year chair warranty; 30-day free returns | Simpler, lower-cost option |
| SitPro | Nine settings; 3D armrests | 97°–117° | Three-year warranty; 30-day returns | More documented adjustment |
| IKEA JÄRVFJÄLLET | Headrest, lumbar, 2D arms, seat depth and height | Synchronised tilt; three-position lock | 10-year guarantee; 365-day returns | Long guarantee and broad named adjustments |
| Apex Comfort Resolute Mesh | Folding padded arms; 500–620 mm seat height | Tilt tension and lock | Two-year warranty; 14-day returns | Higher published static rating |
These are manufacturer claims and policies. Read the current terms for exclusions and return conditions; a return window does not prove that a chair will suit you.
SitOne: the simpler option #
Desktronic’s UK range page describes SitOne with six adjustment points and four recline positions. The company also lists a three-year chair warranty and 30-day free returns.
SitOne is the sensible first comparison when budget matters and its controls cover the adjustments you need. Before buying, inspect the live product page for the exact controls included on the selected variant. “Ergonomic” is not a guarantee of comfort or a health outcome.

SitPro: more documented adjustment #
Desktronic publishes nine settings for SitPro, including 3D armrests, and a 97°–117° recline range. It lists a maximum user load of 136 kg and recommends the chair for heights up to 192 cm. The published terms include a three-year warranty and 30-day returns.
Those limits make SitPro easier to screen on paper, but they do not establish fit. Check seat dimensions and every adjustment against your body and desk. A maximum height recommendation covers only one part of chair fit.

Other alternatives #
IKEA JÄRVFJÄLLET: long guarantee and named adjustments #
IKEA lists an adjustable headrest and lumbar support, 2D armrests, adjustable seat depth and height, synchronised tilt and a three-position tilt lock. The chair is tested to 110 kg and IKEA cites EN 1335 and ANSI/BIFMA x5.1.
Its official page stated a 10-year guarantee and 365-day returns when checked. Read the current conditions and check the dimensions against your body and desk rather than treating those terms as proof of comfort.

Apex Comfort Resolute: a higher-capacity comparison #
Apex Comfort describes a high-back mesh chair with a moulded-foam seat, folding padded arms, tilt tension and lock, and a 500–620 mm seat-height range. It publishes a 180 kg static rating and describes the design as 24-hour rated; both are manufacturer claims rather than independent test results from Home Desk Lab.
The official page stated a two-year warranty and 14-day returns when checked. Confirm the current terms and whether its controls and dimensions suit you.

What to check before ordering #
- Seat height: confirm that you can place your feet securely while keeping the desk at a usable typing height.
- Seat depth: look for enough thigh support without the front edge pressing behind your knees.
- Armrests: check their height and movement against your desk, keyboard and preferred posture.
- Recline: decide whether fixed positions or a particular angle range matters to the way you work.
- Published limits: treat load and height figures as boundaries to verify, not evidence of comfort.
- Returns and assembly: read the live UK terms, including condition, packaging and collection requirements.
SitOne or SitPro? #
Compare SitOne when its six adjustments meet your checklist and SitPro when you need a documented extra such as 3D armrests or its stated recline range. Add JÄRVFJÄLLET when its named adjustments and guarantee matter, or Resolute when its published static rating and seat-height range address a requirement. If no page gives you enough information to judge fit, keep looking rather than buying from the label alone.
A chair is only part of the setup. Desk height, monitor position and movement habits also matter to how a workstation feels. If you want to alternate between sitting and standing, read our UK standing desk guide.
Can an ergonomic chair fix pain? #
We do not make that claim. A chair may help you arrange your workstation, but product specifications cannot predict a health outcome. For persistent pain or symptoms, seek appropriate professional advice rather than relying on a product guide.
