If you are under 5’5”, most office chairs are built for someone else. The seat sits too high, your feet dangle, your lower back gets no support because the lumbar curve hits the wrong place, and the seat pan is too deep for your thighs. The fix is not a footrest — it is a chair that fits your frame.
This guide compares five chairs by the numbers that matter for shorter users: minimum seat height, seat depth, and lumbar support placement. All specs come from manufacturer pages and independent reviews; prices were checked in November 2026.
The one number that matters: minimum seat height
For users under 5’5”, the ideal seat height is 15 to 17 inches from the floor to the seat, so your feet rest flat with your knees near a right angle. For a 5-foot person, 15–17 inches is the target. Most standard office chairs bottom out at 18–19 inches — too high.
Seat depth matters second: a shallower seat (15–17 inches deep) lets your back touch the backrest while your knees stay slightly bent. A standard 18–19-inch seat pan pushes a shorter person forward, away from the backrest, and the lumbar support becomes useless.
The short answer
| Chair | Min. seat height | Seat depth | Approx. price |
|---|---|---|---|
| Herman Miller Aeron, Size A | 14.8 in | 15.75 in | ~$1,095+ |
| Steelcase Series 1 | 16.5 in | 15.75–18.5 in | ~$400–$500 |
| Branch Ergonomic Chair | 17 in | 17 in | ~$329 |
| FlexiSpot C7 | 17.3 in | 17.7 in | ~$300 |
| Sihoo M59AS | 17.7 in | 17.3 in | ~$200 |
Pick the Herman Miller Aeron Size A if budget is not the deciding factor — it is the only premium chair built in a genuinely small frame. Pick the Steelcase Series 1 for the best balance of low seat height and price. Pick the Sihoo M59AS if your budget is under $250.
1. Herman Miller Aeron, Size A — best high-end chair
The Aeron is the benchmark ergonomic chair, and Size A is the small version — built for shorter and smaller users, not just a standard chair with the seat lowered.
- Size A frame: built for users under 5’4”
- Minimum seat height: 14.8 in — the lowest of any chair in this guide
- Seat depth: 15.75 in
- Price: ~$1,095 and up
The 14.8-inch minimum is the number no other chair here matches. If you are 5’0” or under, the Aeron Size A is the only premium chair that lets your feet rest flat without a footrest. The Size A frame is also narrower, so the armrests sit closer to your body and the backrest curve hits the right place on a shorter torso.
The cost is the obvious objection. At over $1,000, the Aeron costs three to five times the budget options. It is a buy-once chair — 12-year warranty, parts available for decades — but only you can decide whether that is worth it.
2. Steelcase Series 1 — best balance
The Steelcase Series 1 is the favourite of short professionals who want a premium chair without the Aeron’s price. Its compact frame and multi-adjustable features are built for smaller bodies.
- Seat height: 16.5–21.5 in
- Seat depth: 15.75–18.5 in (adjustable)
- Price: ~$400–$500
The 16.5-inch minimum is low enough for most people under 5’5”, and the adjustable seat depth — down to 15.75 inches — means your back can actually reach the backrest. The Series 1 also has the best build quality in its price range: Steelcase’s warranty and parts support are the closest thing to Herman Miller’s at half the price.
3. Branch Ergonomic Chair — best mid-range
The Branch Ergonomic Chair is the mid-range pick: a clean design, solid adjustability, and a price that undercuts Steelcase.
- Seat height: 17 in minimum
- Seat depth: 17 in
- Price: ~$329
At 17 inches minimum, the Branch sits right at the top of the ideal range for shorter users — fine for someone 5’3”–5’5”, but marginal for someone under 5’2”. The seat depth is fixed at 17 inches, which is on the deep side for a shorter person. If you are 5’4” or taller, the Branch is a good value. If you are shorter, look at the Steelcase or the Aeron.
4. FlexiSpot C7 — best with a headrest
The FlexiSpot C7 adds something the chairs above it do not: a height-adjustable headrest, which matters if you lean back during calls or long reading sessions.
- Seat height: 17.3 in minimum
- Seat depth: 17.7 in
- Price: ~$300
Like the Branch, the C7’s 17.3-inch minimum is at the edge of the ideal range. It works for shorter users in the 5’3”–5’6” band, but someone 5’1” will still dangle. The headrest and the price make it the best value in this guide for the taller end of “short”.
5. Sihoo M59AS — best budget pick
The Sihoo M59AS is the budget option that actually fits shorter users, rather than just being cheap.
- Seat height: 17.7 in minimum
- Seat depth: 17.3 in
- Price: ~$200
At 17.7 inches, the M59AS is the highest minimum seat height in this guide — it is the least suitable for very short users. But at $200, it is also the cheapest chair here by a wide margin, and for someone 5’4”–5’6” it is a fair everyday chair. If you are under 5’3”, spend the extra $100–$200 on the Steelcase Series 1 instead.
How to choose by your height
- Under 5’1”: Herman Miller Aeron Size A. Nothing else goes low enough.
- 5’1”–5’4”: Steelcase Series 1. The 16.5-inch minimum and adjustable seat depth are the right combination.
- 5’4”–5’6”: Branch Ergonomic Chair or FlexiSpot C7. Both sit at 17 inches, which works at this height.
- Budget under $250: Sihoo M59AS, and add a footrest if your feet do not reach the floor.
One more thing: your desk matters as much as your chair. A chair that drops to 16 inches is only useful if your desk also drops low enough — see our guide to standing desks for small spaces, where the FlexiSpot E7’s 22.8-inch minimum is the lowest in its class.
