Why the Right Ergonomic Chair Matters
Choosing the right ergonomic office chair plays a decisive role in preventing musculoskeletal problems such as pain in the lower back, neck and hips. Below we set out everything you should look for to ensure comfort and good ergonomics at your desk.
The 6 Criteria for Choosing the Best Office Chair
1. Seat depth and proper fit
Does the seat feel comfortable and suit the shape of your body? The seat surface should not be too large for your legs, otherwise it will press behind your knees or stop you from resting your back fully against the lumbar support. For freedom of movement, there should be at least 1.3 cm of space between the front edge of the seat and the back of your knees. The seat should be long enough to support at least three-quarters of your thigh length. Many ergonomic seats have an adjustable seat surface to fit different body types, as well as a front edge that curves downwards to avoid pressure behind the knees. The surface should also be contoured for even weight distribution, soft and comfortable, without pressing on the thighs and buttocks, while the back of the seat should provide comfortable support.
2. Chair height adjustment
Is the seat height adjustable? For greater comfort, the seat should be adjustable so you can set the height of the seat surface while seated. Some seats have a mechanical height adjustment (a turning mechanism), which is less convenient but acceptable in some cases. Ideally, the seat should be height-adjustable to suit everyone.
Is the height-adjustment range enough for all users’ needs? You should be able to adjust the seat height so that the front of your knees is level with or slightly below your hips and your feet rest firmly on the floor. In most cases you will not need to use a footrest. The height-adjustment mechanism should be easy to reach and operate while seated.
3. Lumbar support and backrest
Does the seat have comfortable lumbar support? Many seats have lumbar (lower-back) supports that can be adjusted up and down, are curved and sometimes also adjust forwards and backwards, to better fit the shape of your back. If the seat is used by several people, this adjustability may be essential. If the seat has a fixed support height, is comfortable when you sit back against it, and you will be the main user, then fixed support may be acceptable.
Is the backrest large enough to provide good support? Many seats have a backrest large enough to support the lower back and the thorax (torso), up to the level of the shoulder blades. The backrest should not interfere with the movement of your elbows behind your torso.
4. Comfort for long-term use
Is there enough room for your hips when you sit? Insufficient room for your hips can make you sit too far forward on the seat, leaving your thighs without enough support. When you sit, the seat surface should be at least 3 cm wider than your hips and thighs on each side.
Is the seat still comfortable after at least 60–120 minutes of sitting? If the seat is made of low-density foam, continuous use can deform it permanently so it no longer provides adequate support. Insufficient padding (cushioning) and an unsuitable seat contour can cause discomfort and fatigue in the hips and back. Ideally, you should sit on a chair for a few days at work to understand how comfortable it is for you.
5. Recline mechanism and castor base
Does the backrest recline so it supports your back in different positions? Movement of the backrest while you sit helps maintain a healthy spine. Look for seats that let you recline easily, that provide good support in various reclined positions and that adapt to the position of your back. Locking the backrest in one position is generally not recommended, as it limits the support given to the back. Research studies confirm the benefits of using seats that support a dynamic sitting posture rather than encouraging a static position.
Does the seat have a five-leg base? If chair mobility is important for your work, the seat should have at least five legs with castors that glide easily over the floor. Seats with four castors tip over more easily than those with five or more.
6. Adjustable armrests
Do you need armrests on your seat? Most ergonomic seats have armrests, which should be adjustable. The chair’s armrests should be wide, contoured, padded and comfortable. While seated, you should be able to easily adjust their height and move your arms when needed, for example when typing or using the mouse. For this reason, look for a chair with armrests that adjust in both width and height.
Choose the Chair That Fits You
Choosing the right ergonomic chair is an investment in your long-term health and productivity. A good chair will support you for years, preventing pain and improving your work experience. Remember that the most expensive ergonomic chair is not necessarily the best for you — the right choice depends on your individual needs.
