How to choose the right gaming chair for your height and weight

Your height, the seat height range and the maximum weight are the three data points that decide whether a chair is going to fit you. Design, color and lighting come after, and they don't fix a chair that's too big or too small.

When buying a gaming chair we tend to look at looks first, or at flashy features that don't add much in practice. And the basics keep getting overlooked: how the chair adapts to your body. Here are the criteria, and the real measurements for each model in a table, so you can check before buying instead of after.

1. Chair size: it's not looks, it's ergonomics

The chair needs to fit you. If it doesn't fit your body, it doesn't matter how good looking it is: you won't be comfortable, and over time your posture will show it.

What to check

• Backrest height: measure the distance from your waist to your neck. It's the key measurement because that's where the neck cushion needs to sit, one of the most noticeable ergonomic features on a gaming chair. If it ends up above or below the top of your neck, it's not giving real support. Our backrests range from 84 cm (NYX) to 89 cm (FREYA ELITE). Among the ergonomic models, MYLA is the only one with a fully height adjustable backrest, across 12 positions (6 cm), with the integrated lumbar support moving up and down with it. On NOMA and NOMA OFFICE the backrest is fixed height, and what adjusts separately is the headrest (10 cm of travel) and the lumbar support (4 positions), which is where you really fine tune neck and lumbar support on these two models.
• Backrest width: your shoulders shouldn't spill outside it, nor should the side wings press inward. Check both inner and outer width. The wings should cradle you without pinching.
• Seat height: with the chair adjusted, your whole foot flat on the floor and your knee at a right angle. If your chair doesn't get you there, section 3 explains what to do.
• Armrests: they need to fit under your desk when you're not using them, and support you facing the monitor, elbows at 90° and shoulders relaxed. The spec that decides whether they fit under your desk is the minimum height from the floor to the armrest, which ranges from 62 cm (FREYA and MYLA) to 70 cm (NOMA). Measure the clear space under your desktop and compare. How to set them up is detailed in the posture guide.
• Seat width: enough to sit without the sides pressing on your hips or thighs. It's the measurement most people skip, and the one that shows up most from the third hour on.

2. The measurements for each VALK chair

The first four are our gaming chairs. MYLA, NOMA and NOMA OFFICE aren't: they're under ergonomic chairs, built for long days of remote work or study. If you switch between work and gaming at the same desk, either family works, and the difference comes down more to material and adjustment type than to size.

3. Seat height and pistons: the adjustment almost nobody checks

We don't all have the same leg length, and not all desks sit at the same height. That's why it matters for a chair to have a quality adjustable piston, and even better, for alternative pistons to exist for your measurements.

• If you're under 1.65 m, a shorter piston helps you keep your feet on the floor without giving up good posture. On NYX and GAIA there's a shorter piston that lowers the seat by about 3 cm.
• If you're over 1.85 m, or your desk is tall, you need the opposite. The FREYA accepts a longer piston with 4 cm more travel.

If the chair sits too high for you and you don't want to touch the piston, the OSMA footrest solves most cases. And if the problem is the desk rather than the chair, a height adjustable desk like the SKULD tackles it from the other side. Pistons and other parts are in spare parts, so you can fit your chair to your measurements instead of settling for a standard size.

4. Weight: the number, and what's behind the number

Our chairs' maximum weight ranges from 120 to 150 kg. NYX, NOMA and NOMA OFFICE top out at 120 kg, FREYA, GAIA and MYLA reach 130 kg, and FREYA ELITE goes up to 150 kg certified under the UNE-EN 1335 standard.

That said, the number alone doesn't say much. A figure on a spec sheet is easy to write, and plenty get written in this industry with nothing behind them. What's worth checking is what backs it up:

• The base: aluminum on FREYA, FREYA ELITE, MYLA, NOMA and NOMA OFFICE, nylon on NYX and GAIA. Aluminum holds up better to heavy use and sudden weight when you get up.
• Foam density: the more you weigh, the sooner a soft foam shows it. Figures by model are in the next section.
• Seat width: the practical limit is often not the weight, it's the width. If the sides press on your hips, the chair is too small for you even if the scale says you're well within limits.
• Margin: if you're close to the max and spend long hours sitting, go up a step. Running at 95% of capacity for years isn't the same as running at 70%.

If you're over 100 kg, FREYA ELITE is the most straightforward choice: it's the largest, it holds the most weight, and it's the only one with a certified capacity under a standard. The differences versus the FREYA are broken down in Freya or Freya Elite: which one fits you.

5. Padding and density: the key to avoiding sagging

Padding goes unnoticed when buying, and it's where quality shows up most over the medium term. A lot of budget chairs use low density foam, between 25 and 35 kg/m³, and that translates into sunken seats within a few months.

Chairs with cold cured foam and densities from 50 kg/m³ upward offer:

• firm support that doesn't sag easily,
• greater durability with daily use,
• a stable, secure feel.

This matters especially if you weigh over 70 kg or do long sessions. Our figures, in case you want to compare them against other brands: FREYA and GAIA use 55 kg/m³ in the seat and backrest, cold cured. FREYA ELITE goes up to 60 kg/m³ in the seat and 55 kg/m³ in the backrest. NYX has 55 kg/m³ in the seat and 50 kg/m³ high density in the backrest. On MYLA, NOMA and NOMA OFFICE, foam density doesn't apply the same way, since the seat and backrest are stretched mesh.

6. Fabric, PU leather or mesh: it depends on your environment

• Fabric: breathable and cool, the sensible option if you sweat or live somewhere hot. In exchange it asks for a bit more upkeep. We cover it in mesh or fabric.
• PU leather: cleans up in one pass and has a more understated look. If it's not microperforated it retains more heat, which is why on the PU leather NYX we use a microperforated finish. To make it last, the key is avoiding cracks: we explain it in how to avoid cracking in PU leather.
• Mesh: the most ventilated option there is. It's the territory of our ergonomic chairs, with MYLA leading the way, ideal for long days and for the months when the fan just can't keep up.

7. And posture

Picking the right size is half the job. The other half is sitting correctly: height, armrests, cushions, recline and screen, each in its place. You'll find the exact degrees and centimeters for each model in how to sit correctly in a gaming chair.

FAQ

How do I know if a chair fits me by height and weight

Two checks. Sitting down, your whole foot should rest on the floor with your knee at a right angle, and your weight should stay below the model's maximum, with margin if you spend long hours sitting.

Across our range, seat height goes from 46 to 56 cm depending on the model, and maximum weight from 120 to 150 kg. Both figures are together in the table above. If you're between two sizes, decide based on the distance from the floor to the back of your knee, not your height: two people at 1.80 m can need different seat heights.

What measurements should I check if I have little desk space

Two: base diameter and the minimum height from the floor to the armrest. The base determines the footprint, and ours range from 650 mm on MYLA to 720 mm on NOMA. Armrests start between 62 cm (FREYA and MYLA) and 70 cm (NOMA), so measure the clear space under your desk before deciding.

Also keep in mind that a chair that reclines up to 160° needs nearly a meter of clear space behind it to open fully, so measure what's behind you too. And if the armrests don't fit under the desk, you'll end up sitting far from the desktop with your arms stretched out, which is exactly the posture that loads up your shoulders.

Which gaming chair holds the most weight

The FREYA ELITE, at 150 kg certified under the UNE-EN 1335 standard. Behind it are FREYA and GAIA at 130 kg and NYX at 120 kg.

Certification is what separates a measured figure from a number pulled out of thin air, and not every brand has it. If you're close to the limit, also look at the base (aluminum on FREYA and FREYA ELITE) and the foam density, which is what determines whether the seat is still firm in two years.

Which gaming chair should I choose if I'm under 1.65 m

The FREYA, which sits lowest as standard: 46 cm seat height. If it's still too high, NYX and GAIA accept a shorter piston that lowers the seat by about 3 cm.

The alternative, cheaper and works in most cases, is leaving the chair at the right height for your arms and resting your feet on a footrest like OSMA. What you can't fix is sitting high with your feet dangling: all the weight lands on your thighs, and you feel it within half an hour.

Which gaming chair should I choose if I'm over 1.90 m

The FREYA ELITE. It's the only one in the range built up to 200 cm, with the seat going up to 56 cm and 150 kg maximum weight.

It's also the largest in backrest and width, which keeps your shoulders from spilling outside the side wings. Among the ergonomic models, MYLA reaches 195 cm and shares that same 48 to 56 cm seat height range.

Do I need a short piston or a long one

Short if, with the chair at its lowest, your feet don't reach the floor. Long if, with the chair at its highest, your elbows end up below the desktop.

If you're in neither case, leave things as they are: the standard travel covers most body and desk combinations. When it is needed, pistons are in spare parts, and swapping one is a single part, not an overhaul.

Choosing the right chair for your body isn't an aesthetic decision: it's about health, comfort and durability. Compare measurements, check the spec sheets and decide what adjustment you actually need. A brand offering alternative pistons, well placed cushions and materials described with real data is a good sign.

And if you're torn between two models, reach out and we'll tell you which one fits your height, your weight and your desk. That, more than any LED or massage cushion, is what makes the difference. You can see the full range in gaming chairs and in ergonomic chairs.
