How Does a Chair Finder Help Find the Right Chair for You?

Office chairs are sized like clothing, and the Chair Finder starts from the two numbers that matter most: your height, which determines the right seat-height range and gas cylinder, and your weight, which determines the chair's build, mechanism and weight rating. You answer ten short questions, our ergonomic specialists personally review your answers, and you receive chair recommendations matched to your body and workspace by email - free, with no obligation to buy.

The questions also capture how you sit and how you prefer your lower back supported. Some people like adjustable lumbar support that gently fills the gap between the chair and their lower spine; others prefer a flat, neutral backrest with no forward pressure. Your answer helps us choose between chair families with very different back designs.

If you are in the San Francisco Bay Area, you can also visit the ErgoDirect showroom in San Carlos, California and try a wide selection of ergonomic chairs in person - call 888-456-3746 to arrange a visit. And if you would like professional help with your whole workstation, the form lets you request an optional assessment by an independent licensed ergonomist, online or in person.

FAQ - Choosing the Right Office Chair

There is no single best ergonomic chair - the right chair is the one that matches your body and workspace. A chair that is perfect for a 6'2" user can be uncomfortable for someone who is 5'2". Start from your height, weight, preferred back support and budget, then compare only chairs that fit those numbers. Our Chair Finder does this matching for you, with a specialist reviewing your answers.

A chair fits when the seat height lets your feet rest flat on the floor, the seat is wide enough for your hips, the seat depth leaves a two-inch gap behind your knees, and the weight rating comfortably covers you. Measure yourself using the guides on this page, or answer the ten questions above and let our specialists match chairs to your measurements.

Shorter users - around 5'2" and under - usually need a lower seat height than standard chairs provide, and often a shallower seat. If your feet dangle or the seat edge presses the back of your knees, the chair is too big. Look for chairs offered with a lower gas cylinder and a smaller seat - in the Chair Finder, your height and weight answers tell us exactly which of these options you need.

Check three measurements: seat height (measure from the floor to just below your knee-cap while seated), seat width (the distance between two books placed against your hips) and seat depth (buttocks to the back of the knee, minus two inches). Compare them with the chair's specifications - or submit them through the Chair Finder and we will do the comparison for you. See the measuring guides below for step-by-step instructions.

It depends on how you like your lower back supported. Many people with lower back discomfort do best with adjustable lumbar support that gently fills the gap between the chair and the lower spine; others prefer a flat, neutral backrest. The Chair Finder asks exactly this question, plus where you feel discomfort, and you can optionally request an assessment by an independent licensed ergonomist. For persistent pain, talk to a medical professional as well.

A 30-inch fixed desk is taller than the typical 29-inch office desk, so your chair needs to adjust a little higher than average for your elbows to reach a comfortable typing height - shorter users may also need a footrest. This is exactly why the Chair Finder asks whether your desk is fixed or height-adjustable and how tall it is; we match the chair's height range to your desk, not just to you.

While seated with your feet flat on the floor and knees at about 90 degrees, measure from the floor to just below your knee-cap, wearing the shoes you use at your desk. That distance is your ideal seat height, and it should fall inside the chair's cylinder range. Follow our seat height measuring guide below, including the diagram.

Office chairs are sized like clothing: the right size is set by your height (seat height range), your hip width (seat width), your leg length (seat depth) and your weight (chair build and rating). Petite and big-and-tall users in particular should never buy a 'standard' chair unseen. Measure using the guides on this page, or answer the Chair Finder questions and let a specialist size the chair for you.

Once you know your seat height, seat width and seat depth, compare them against the seat dimensions listed in each chair's specifications - the chair's ranges should bracket your numbers, not just touch them. If you would rather not compare spec sheets, submit your answers through the Chair Finder and our specialists will shortlist chairs whose dimensions match your measurements.

Why Chair Fit Matters

Most office chairs are built for an "average" body - but almost nobody is average. These two measurements tell you more about chair fit than any product photo.

How to Measure Seat Height

  1. Sit down with your feet flat on the floor and knees bent at about 90 degrees.
  2. Measure from the floor to just below your knee-cap.
  3. That distance is your ideal seat height - measure in the shoes you usually wear at your desk.

Standard chair cylinders only cover a middle range of heights - that is why the Chair Finder asks for your height.

How to Measure Seat Width & Depth

  1. Width: sit on a bench or a sturdy table and place a book against each side of your hips. The distance between the two books is your ideal seat width.
  2. Depth: while seated, measure from the back of your buttocks to the back of your knee, then subtract 2 inches for leg clearance. That number is your ideal seat depth.

Too deep and you slide forward; too narrow and the armrests press into your hips.
