Best Office Chairs Under £400
You don’t need to spend £1,000 to get a proper office chair
but this is where the difference starts to matter.
At around £300–£400, you’re no longer choosing between “good for the price”
you’re choosing chairs that are genuinely comfortable for daily use.
These are chairs that can support long hours, hold their shape over time,
and stop you thinking about them once you’re sat down.

At this price, the difference isn’t features — it’s consistency.
Cheaper chairs often feel fine at first, but degrade quickly.
At £300–£400, you start getting chairs that hold their support,
stay comfortable across full days, and don’t need constant adjustment.
This is where a chair stops feeling “good for the price” and starts feeling genuinely reliable

BEST OVERALL
SIHOO Doro C300
A highly adjustable chair
that works for most people
The Doro C300 gives you the kind of adjustability that actually improves comfort —
including dynamic lumbar support, breathable mesh, and a structure that holds up over long sessions. It’s not trying to be a luxury chair, but it solves the biggest problems people run into when working from home:
posture support, airflow, and fatigue over time. A strong all-round choice if you want something dependable without overthinking it.
Typical price £280 – £380

BEST VALUE
IKEA MARKUS
A simple, durable chair that
just works
The MARKUS is still one of the safest choices you can make — even at this price level. It doesn’t have lots of adjustments, but that’s part of the appeal.
It’s designed to work without constant tweaking, and the high back provides consistent support throughout the day. Not perfect for everyone, but reliable, durable, and easy to live with. If you don’t want to think about your chair, this is the one.
Typical price £160
Price checked May 2026
BEST PREMIUM
FlexiSpot OC3
A more refined chair with better
control over your setup
The OC3 gives you more control over how the chair fits your body —
including adjustable armrests, lumbar support, and a breathable mesh design that holds up over longer sessions. It’s not trying to compete with £1,000 chairs, but it closes the gap enough that you start to feel a real difference day to day. If you’re sitting for long hours and want something closer to a “proper” office chair, this is where that shift happens.
Typical price £170 – £220
Price checked May 2026

These chairs focus on:
- Support that lasts through the day
- Materials that don’t collapse quickly
- Designs that don’t need constant adjustment
They’re not just comfortable at first — they stay comfortable.

Buying advice
Don’t focus on how a chair feels in the first 10 minutes.
Think about:
- whether it still feels supportive after a few hours
- whether you’re constantly adjusting it
- whether it holds your posture without effort
A chair that disappears while you work is usually the right choice.

FAQ
Are office chairs under £400 actually good enough? Yes — this is where chairs start to feel properly usable for daily work. The key is choosing one that holds support over time.
What’s the difference between £200 and £400 chairs? Consistency. Cheaper chairs often flatten or lose support, while better-built chairs stay comfortable throughout the day.
Do I need an ergonomic chair at this price? Not necessarily. What matters more is how the chair supports you over time, not how many features it has.
Is mesh or cushioned better? Mesh tends to work better for long sessions because it improves airflow. Cushioned seats can feel softer at first but may compress over time.
How long should a chair at this price last? A good chair under £400 should last several years with daily use. Build quality is the main difference at this level.
