The Complete Guide to Ergonomic Computer Chairs

It’s the question we get asked every day: What is an ergonomic computer chair? To explain this very important item of office furniture, we’ve created a comprehensive guide to chair ergonomics. We’ll explain the various benefits and features involved so you can make an informed buying decision that will benefit both your health and your efficiency in the office.

What Does 'Ergonomic' Mean?

If you’re here to get an answer to the question “what is an ergonomic chair”, we’ve got you covered. Because people are spending more time in front of computer screens than ever before, the need for comfortable, supportive office seating has never been greater. That’s why more and more people are thinking carefully about chair ergonomics. As well as chairs, there are a range of ergonomic products designed to make the most of your desk space.


The formal definition of ergonomic is:

The science behind the design, construction or arrangement of things people use to ensure maximum safety and efficiency. In relation to office chairs, this means a design that gives the user support and comfort in order to minimise the risk of pain while sitting at a desk.

What Are the Benefits of an Ergonomic Computer Chair?

Now that we’ve covered the ergonomic chair meaning, we can delve into the many benefits associated with having a comfortable, adaptive and supportive sitting position while working at a desk. Leather, fabric and mesh desk chairs with the full range of adjustment options can all drastically improve your posture and reduce pain in the workplace. There are many benefits associated with chair ergonomics, but here are a few of the most impressive.

Reduces Neck & Back Strain

If you sit in an inappropriate position for hours at a time, you’ll probably suffer from pain in your lower back, shoulders and neck. Over time, the consequences of this scenario can be devastating. Lower back pain is one of the leading causes of office-based work absence. And long-term neck pain can lead to a debilitating condition called spondylosis — the loss of cartilage in the vertebrae.


Seating with your legs planted on the floor, your back straight and your eyes level with what you’re reading will significantly reduce the chances of developing these painful conditions. Office chairs for back pain are designed to manipulate your body into the healthy sitting position required.

Increased Adjustability

What is an ergonomic chair? Well, it’s a chair featuring a range of functions designed to create the best possible sitting position for the individual. A good product will give you the option of making the following changes:


  • Headrest adjustments
  • Armrest adjustments
  • Seat height adjustments
  • Backrest tilt adjustments
  • Backrest rigidity

Supports Better Posture

As a simple rule of thumb, the best possible sitting position is one that keeps your back straight, your thighs parallel with the floor and your arms at a right angle. Ergonomic desk chairs feature a range of adjustment options to ensure all of these positional objectives are met. You can adapt your seat to your height and body shape — ensuring a good working posture at all times.

Reduces Pressure on Hips

A hard, rigid or uneven seat can make your hips work harder than they need to. Ideally, an upright seated position that keeps your thighs parallel to the floor will minimise the strain on your hips and prevent both short-term and long-term pain. An ergonomic chair may also include additional padding to reduce the pressure further.

Improves Productivity

If you’re in chronic pain while working at your desk for hours at a time, you won’t be able to fully focus on your work. You may need regular breaks away from your workstation. And even when you’re at your desk, your concentration levels won’t be anywhere near their best. But an ergonomic chair is designed to relieve strain on your body — and therefore pain. You’ll be happier, more motivated and, ultimately, far more productive when you have an ergonomic chair taking the strain.

Improves Circulation

Studies into sitting positions have revealed that sitting still for just one hour can significantly increase the risk of developing poor blood circulation, heart attacks and strokes. An ergonomic chair can help to reduce this risk in two ways:


  • Allows you to change your sitting position regularly
  • Promotes a healthy sitting position that can optimise blood circulation


Note: Even with an ergonomic office chair, you should aim to stand up and move around a little every 45 minutes or so.

Features of an Ergonomic Computer Chair

What does an ergonomic chair mean? At first glance, it looks like any other chair. However, a good product gives you a host of adjustment options and enhanced features — designed to manipulate your body into the perfect seated position. The most effective features to look out for when choosing an office chair are:

Adjustable Seat Height

A one-size-fits-all approach to office seating will always result in pain and discomfort for at least a few employees. That’s because the height of people varies so greatly. The most important feature of any ergonomic chair is seat height adjustment, as the optimum sitting position for everyone involves the feet being firmly planted on the ground while the upper legs are perfectly parallel to the floor. In most cases, a simple lever to the side of the chair allows the user to set the seat height in very precise increments.

Lumbar Support

Lumbar support is a design feature that takes away pressure and strain from the lower back. Without it, users must resort to additional items — such as cushions — to reduce the space between the lower back and the backrest. Made with hygienic, breathable fabrics, today’s lumbar support is more effective than ever. And if it’s designed correctly, it will maintain the natural curvature of your spine for long periods.

Adjustable Tilt & Tilt Lock

Many ergonomic office chairs allow reclining. This is a great feature to have when you’re switching between different tasks — or when you want to relax for a few minutes. But there will be times when you need your upright sitting position to be fixed firmly in place. An adjustable tilt and lock mechanism allows you to find the perfect tilt angle for you that won’t move when the backrest takes your weight.

Adjustable Arm Height

In most cases, the optimum position for your forearms while typing should be at a right angle with your upper arms. For the best results, make your armrests and extension of your desk. To do this, you’ll need to adjust them so they’re exactly the same height as your desk. A good chair allows quick and easy changes to the height of the arms.

Adjustable Seat Depth

When asked “what is an ergonomic chair”, too many retailers forget to talk about seat depth. In simple terms, seat depth is the distance between the back of the seat and the backrest. An ergonomic chair allows you to slide the seat back and forth to find the perfect position for your body. You’ll know you’ve found the perfect seat depth when both your back and thighs are fully supported.


Shorter people have a tendency to perch on the edge of their office chairs to ensure their feet remain on the floor. But sitting like this offers no support for their backs, which can lead to pain and immobility over time.

Built-in Head & Neck Support

A high-quality ergonomic office chair should allow the user to adjust the height of the headrest for maximum head and neck support. If your headrest can take the weight from your neck and upper back, the muscles in those areas can relax. This doesn’t just prevent pain, but it also promotes better circulation.


Note: If you’re sitting perfectly upright to type or use your computer, you won’t need your headrest. However, if you decide to recline for a while, a headrest at the perfect height can maximise comfort and support.
