Choosing the right office chair is one of the most important decisions you’ll make for your home or workplace setup. Sit in the wrong one for long enough and you’ll feel it, tight lower back, sore hips, stiff shoulders.
The good news: you don’t need to spend a fortune to get it right. You just need to know what to look for.
How Many Hours a Day Will You Be Sitting?
This is the single most important question before buying any office chair.
- Under 4 hours a day: A simple chair with basic height adjustment and decent padding is sufficient. You don’t need heavy ergonomic features.
- 4–8 hours a day: This is the most common range for home workers. Look for proper lumbar support, adjustable height, and a breathable material.
- 8+ hours a day: Full adjustability becomes essential, lumbar depth, seat tilt, adjustable armrests, and a high backrest. Don’t compromise here.
The 6 Most Important Features of an Office Chair
1. Seat Height Adjustment
Seat height is the most critical adjustment on any chair. Set it so your feet rest flat on the floor, your knees are level with or slightly below your hips, and your elbows sit roughly level with the desk surface.
Most chairs adjust between 40–55 cm. If you’re shorter or taller than average, check the seat height range carefully, not all chairs suit all heights.
What to look for: A pneumatic gas lift that adjusts smoothly. A range of 40–57 cm covers most adults.
2. Lumbar Support
The lumbar region is the inward curve of your lower spine. Without support here, your lower back rounds forward over time, causing fatigue and pain.
Good lumbar support sits in the small of your back and maintains the spine’s natural curve. Adjustable lumbar depth and height gives a more precise fit than fixed support.
What to look for: Adjustable lumbar where possible. At minimum, a backrest that makes contact with the lower back naturally when seated upright.
3. Seat Depth
Seat depth is the distance from the front edge of the seat to the backrest. Too deep, and you can’t reach the backrest. Too shallow, and your thighs aren’t properly supported.
What to look for: A 2–4 finger gap between the back of your knees and the front of the seat. Around 40–46 cm suits most people.
4. Backrest, Mid-Back vs High-Back
A mid-back chair supports the lumbar and mid-spine. A high-back chair supports all the way to the shoulders, better for longer sessions and taller users.
What to look for: High-back for 6+ hours of daily use. Mid-back works well for moderate use under 6 hours.
5. Armrests
Armrests reduce strain on the shoulders and neck by supporting the weight of your arms. For desk work, set them so your shoulders sit fully relaxed, not raised or dropped.
That said, armrests aren’t always the right choice. If you’re working in a tight space or sitting close to your desk, armless chairs often work better, they slide fully under the desk and give your body more freedom of movement.
What to look for: Adjustable armrests for long sessions. Armless design for compact spaces or close desk setups.
6. Swivel and Castors
A 360° swivel seat lets you move without twisting your spine. A five-star base is more stable than a four-star.
Castor type matters depending on your floor:
- Nylon castors: Best for carpet
- Soft PU castors: Best for hard floors, won’t scratch laminate or hardwood
What to look for: Match the castor type to your floor surface before buying.

| Faux Leather (PU) | Easy cleaning, smart look | Doesn’t breathe, can feel warm |
| Fabric / Linen | Everyday comfort, neutral rooms | Harder to clean, absorbs spills |
| Velvet / Plush | Style-focused spaces, lighter use | Shows wear faster under heavy use |

What to Check Before You Buy

- Seat depth leaves a 2–4 finger gap behind the knees

- BS 5852 certified, the British Standard for fire resistance in upholstered furniture

Common Mistakes When Buying an Office Chair
- Buying on looks alone. A chair can look great in a photo and be uncomfortable within an hour. Always check ergonomic specs alongside aesthetics.
- Ignoring the seat height range. If the chair doesn’t adjust to your height, no other feature compensates. Check the minimum and maximum figures before buying.
- Assuming expensive means comfortable. Price reflects build quality and adjustability, not automatically comfort. A well-fitted £90 chair can outperform a £400 chair that doesn’t suit your proportions.
- Not checking castor type. Nylon wheels on a hardwood floor will mark it. Match the castor to the floor before purchasing.
- Overlooking room temperature. Faux leather is uncomfortable in a warm room. If your space heats up in summer, mesh is the better choice.
Quick Reference: Which Office Chair Suits You?
| Your Situation | What to Look For |
| Small space or bedroom | Compact footprint, height adjustable |
| All-day desk work (6–8 hrs) | High back, lumbar support, adjustable arms |
| Warm or poorly ventilated room | Mesh back for airflow |
| Hard floors | Soft PU castors or chair mat |
| Taller than average | Seat height range up to 55–57 cm |
| Multiple users | Wide adjustability range |
Start with seat height and lumbar support. Get those two right and everything else becomes easier to evaluate. Match the material to your room, factor in your budget, and run through the checklist before you buy.
When a chair fits properly, you stop noticing it. You just get on with the work.

FAQs
1. Can I use a gaming chair as an office chair?
Yes, but with caveats. Gaming chairs are designed for reclined postures during leisure sessions. For upright desk work, the aggressive lumbar cushions and bucket seat design often push the body into poor posture rather than supporting neutral alignment. For daily desk work, a dedicated office chair performs better.
2. Should my office chair have a headrest?
Only if you recline regularly. For upright desk work, a headrest often goes unused and can push the head forward, creating neck strain over time. If you take regular breaks in a reclined position, a headrest adds comfort. Otherwise it is an unnecessary feature.
3. Can You Work From a Recliner Instead of an Office Chair?
A recliner is comfortable for short periods but not suited to desk work. The reclined angle moves you away from the desk, making keyboard and screen use awkward and straining the neck and wrists over time. For any serious amount of desk work, an office chair keeps you correctly positioned and properly supported.
