You can prefer some better than other but take some advice before buying a chair!

What is an ergonomic chair ?

Not everybody knows exactly what ergonomic means, but it’s getting to the point where everybody knows an “ergonomic chair” is better than just some plain old chair.

So, What Is an Ergonomic Chair?

Ergonomics is the study of equipment designed with humans in mind, meant to reduce operator fatigue and discomfort. Specifically, an ergonomic chair should be highly adjustable, including not just a knob for lowering and raising the chair but adjustability in the back tilt and the height of the arm rests. An ergonomic chair should also have a sturdy frame , a great deal of support, especially in the lumbar region, and padding that has some give and supports your body without losing shape. In conclusion an ergonomic chair is a chair that provides comfort to both the seat and back to the user.

An ergonomic office chair should help increase back and neck support to help improve posture and prevent slouching. Employees frequently experience back pain because they sit in their chairs for long periods of time. This increases stress in the spine, neck, arms, shoulders, and legs as well as in various muscles. A chair that isn’t ergonomically friendly can also aggravate existing conditions.

There are many types of ergonomic chairs available for use in the office. No one type is necessarily the best, but there are some things that are very important to look for in a good ergonomic office chair. These things will allow the individual user to make the chair work well for his or her specific needs.

What features should a good ergonomic office chair possess?

Seat Height

Seat height should be easily adjustable. A pneumatic adjustment lever is the easiest way to do this. This allows the user to have his or her feet flat on the floor, with thighs horizontal and arms even with the height of the desk.

Seat width and depth

A chair seat should feel comfortable when you initially sit down, and should remain that way after you’ve been seated for a significant period of time. The seat should have enough width and depth to support any user comfortably. The depth (from front to back of the seat) needs to be enough so that the user can sit with his or her back against the backrest of the ergonomic office chair while leaving approximately 2 to 4 inches between the back of the knees and the seat of the chair. The forward or backward tilt of the seat should be adjustable.

Seat material.

The material on the seat and back of the ergonomic office chair should have enough padding to be comfortable to sit on for extended periods of time. Having a cloth fabric that breathes is preferable to a harder surface. Skip the leather. A breathable cloth fabric will be better than any harder material. Make sure that there is enough padding for it to be comfortable for long periods of time. Cloth upholstery isn’t as easy to clean as vinyl, and cloth covered foam has the potential to harbor dust mites. However, vinyl–type or leather coverings don’t breathe as easily as cloth, which may cause discomfort after prolonged sitting. Fabric is the key to a chair’s durability. Look for permeable material that breathes, like the mesh Pellicle material in Herman Miller’s Aeron chair, which conforms to the body. If you would like to find more about seating materials you can read more here.

Lumbar support.

Lower back support in an ergonomic office chair is very important. The lumbar spine has an inward curve, and sitting for long periods without support for this curve tends to lead to slouching (which flattens the natural curve) and strains the structures in the lower spine. An ergonomic chair should have a lumbar adjustment (both height and depth) so each user can get the proper fit to support the inward curve of the lower back.


The backrest of an ergonomic office chair should be 12 to 19 inches wide. If the backrest is separate from the seat, it should be adjustable in height and angle. It should be able to support the natural curve of the spine, again with special attention paid to proper support of the lumbar region. If the office chair has the seat and backrest together as one piece, the backrest should be adjustable in forward and back angles, with a locking mechanism to secure it from going too far backward once the user has determined the appropriate angle.


Adjustable armrests are best since they allow user’s arms to rest and relax at the right height. Depending on your work style and requirements, you may not need armrests on your office chair, since they may get in your way as you move around. They should allow the user’s arms to rest comfortably and shoulders to be relaxed. The elbows and lower arms should rest lightly, and the forearm should not be on the armrest while typing.


Any conventional style or ergonomic office chair should easily rotate so the user can reach different areas of his or her desk without straining.

Here IKEA has a nice flash video that shows you how to check the things we talk about until now.

    The Aeron works for me, more than any other chair I’ve used.

    Get an Aeron. If you spend 10+ hours a day in your chair, it will be the best investment you make.

    Great article and very important. My first computer chair had a leading edge (where the lower legs drop down) that was very hard, so hard in fact that it cut off the blood supply to my lower legs and gave me a dose of DVT or deep vein thrombosis (blood clot). Believe me you don’t want to get that! Now I’m blood-thinning medication for the rest of my life.

    Yes, go for a chair that is extremely comfortable, with plenty of padding on the seat just behind the knees and no matter what chair you decide on, make sure to get up and move around about every 30 to 60 minutes. A blood clot that travels to your heart, lungs or brain can kill you, so it’s money and time well spent!

    How much is an Aeron?

  • John May 12, 2007 at 05:49 AMLogin to Reply →

    Some like the aeron, some don’t, but it is very adjustable. I have the global concorde, great except the arm rests are far from optimal.

    Adjustability is the most important factor in a pc chair when a user spends everyday and all day in it. Initial comfort is important before buying one, but the slightest ergonomicly faulty position may take months or more to translate into a physical discomfort, so make sure what you get is adjustable in as many ways possible.

    The Freedom Chair has been amazing for me. If you start to feel the symptoms of RSI (or even before you do) I’d recommend getting one (they don’t come cheap but they’re worth it). And they look like something out of a sci-fi movie (especially from the back). Only wish they’d chosen a better name.

    If you have a back problem, the posture chairs are often recommended. That being the case, why are they not considered the default so that less people develop back problems in the first place? Conventional office chairs encourage slouching.

    I find it strange that you suggest using armrests – personally at out office (programmers) we have experienced back and shoulder pains when using armrests. Simply removing the armrest resolved the problem.

    A Nightingale will work too. Some people actually like it better then Aeron. A bit cheaper then Aeron too.

    It was not the cheapest chair, but it has a lifetime warranty and is ‘office quality’ – not some cheapo.

    Very well written article but MISSING ONE CRUCIAL POINT! It is virtually impossible to create a comfortable chair whilst still following the notion of 90 degrees of bend at the hip. Unless you open that angle (raising the backside, dropping the knees or reclining) you will inevitably end up slouching.

    Do a web search for “Homo Sedens” (Seated Man) by AC Mandal for a really good understanding of the problem and forget 90 degree chairs once and for all.

    Enh, sat in an Aeron for about a year, and don’t think they are all that comfortable. It felt like it cut into my legs and back whenever I tried to move. I did get a crack at trying out a Steelcase Leap, though, and fell in love. (Maybe next time my home chair has a meltdown, but for now I can’t swing the price tag.)

    This is an excellent post that raises the awareness of our lifestyle that can bring health problems for the rest of our lives.

    Back pain is becoming something of normality in today’s society as our lifestyle dictates, and in some cases with dire consequences leaving an individual completely helpless. Work pressure and the onset of increasing age have a part to play in this problem area. With millions of Americans suffering from back pain, it’s the second most common reason for medical visits and work absence

    Sciatica plays a major role in this problem and often ignored through lack of understanding and willingness accept there is an underlying problem.
