How to Choose an Ergonomic Chair Based on Your Height (Malaysia Guide)

"This chair looked comfortable online, but my feet don't touch the floor" is one of the most common things we hear at our Kepong showroom. Most ergonomic chairs are designed around an "average" body size — which means if you're under about 160cm or over about 180cm, the standard settings often don't fit without some adjustment know-how.

Here's what actually matters if you're buying based on your height, and how to check before you buy — not after.

The Measurements That Actually Matter

Forget the marketing photos. These are the four numbers that determine whether a chair will fit you:

1. Seat height range — With your feet flat on the floor and knees at roughly 90°, does the seat height adjust low enough (or high enough) for you? Most chairs adjust between ~42–52cm; shorter users often need something that goes lower.
2. Seat depth — The distance from the front edge of the seat to the backrest. Too deep, and it presses into the back of your knees. Too shallow, and your thighs aren't supported. Look for chairs with adjustable seat depth if you're outside the 165–175cm range.
3. Lumbar support height — Your lower back curve sits at a different height depending on your torso length, not just your overall height. A fixed lumbar bump is a gamble; adjustable height lumbar support is safer.
4. Armrest height and reach — Your elbows should rest at roughly 90° without hunching your shoulders up or reaching down. 3D or 4D armrests (adjustable up/down, forward/back, and pivoting) give you far more room to get this right than fixed 2D armrests.

If You're Under 160cm

• Prioritise a low minimum seat height — check the spec sheet, not just the description.
• A footrest is genuinely useful, not a nice-to-have, if the chair's minimum height still leaves your feet hanging.
• Shallower seat depth (or adjustable depth) matters more for you than for taller users — a seat that's too deep is one of the most common discomfort complaints for shorter users.

If You're Over 180cm

• Check the maximum seat height and backrest height specifically — many "standard" ergonomic chairs top out lower than you'd expect.
• Look for an extended or high-back option if the brand offers one.
• Headrest height range matters — a fixed headrest position that hits the middle of your neck instead of your head isn't supporting anything.

If You're in the 160–180cm Range

You have the most options, but "average fit" still isn't "perfect fit." Don't skip adjusting seat depth, lumbar height, and armrests just because the chair fits reasonably well out of the box — a few minutes of adjustment is the difference between a chair that's fine and one that actually helps your posture.

Why Trying It in Person Beats Any Spec Sheet

Two people who are both 170cm tall can have completely different torso lengths, leg lengths, and posture habits. Spec sheets tell you what's possible; they don't tell you what fits your body. That's really the only honest answer here — and it's why we built a full showroom rather than just a webstore.

At our Kepong showroom, you can sit in the full Reiko and Sihoo range, adjust every setting with our team's help, and figure out your fit in about fifteen minutes — no guesswork, no return shipping if it's wrong.

Prefer a shortcut? Our Find Your Chair quiz asks about your height and usage to narrow down the models most likely to fit before you even walk in.

FAQ

What if my height is right at the edge of two chair sizes? Go with the size that gives you more adjustment room in the direction you need — e.g., if you're at the top of a "standard" range, check whether an "extended" version exists before settling.

Do all ergonomic chairs have adjustable seat depth? No — many budget and mid-range chairs have fixed seat depth. If you're notably shorter or taller than average, this is one of the first specs to check.

Is a footrest a substitute for the right chair height? It helps, but it's a workaround, not a fix. A properly adjusted seat height is always the better starting point; a footrest fills the gap when the chair's minimum height still isn't low enough.
