What is lumbar support? Positioning and adjusting it for a healthier back

Have you noticed yourself shifting in your chair today without knowing why? That’s usually the sign that your lower back lacks support.

Lumbar support is anything that fills the natural inward curve of your lower back, helping your spine maintain its S-shape while you sit. It sits behind the 5 lower back bones and just does its job, so most only notice it when it’s missing.

The purpose of lumbar support is simple: keep your spine in its natural position, so your body doesn't have to work overtime to do it. Let's look at why it matters, where to position it, and which type works best for you.

Key points

• When you sit, more pressure is on your lower back. Good support helps spread out that pressure and can reduce muscle fatigue.
• Place the support at the deepest curve of your lower back. If it pushes against your ribs, it’s too high. If it presses on your belt, it’s too low.
• If your chair doesn’t have built-in support, try using a lumbar pillow as a starting point. For better long-term results, an adjustable ergonomic office chair is the best option.
• Lumbar support alone won’t fix every back problem. Moving regularly and having a well-arranged workstation are just as important.

Interesting fact! Lumbar support is used in many places besides office chairs – even drivers who spend a lot of time on the road depend on it. That’s why many car seats have built-in lumbar support.

Is lumbar support actually useful?

Yes, lumbar support is helpful, especially if you sit for long periods. Sitting puts more pressure on your lower back than standing, and slouching makes it worse. Over time, this strain can cause a backache that you notice later in the day.

The benefits of lumbar support are more useful than you might think. It helps your lower back maintain its natural shape, spreads pressure evenly and makes it easier for your muscles to support your weight.

When your body works less, you feel less tired and can focus better, but lumbar support alone isn’t enough. It’s equally important to move regularly and arrange your workspace well. Using a Desktronic height-adjustable desk together with an ergonomic chair supports you while you sit and stand.

Types of lumbar support

Lumbar support comes in 2 different forms. Built-in lumbar support is part of the chair’s backrest. Its shape is fixed, but you can usually adjust the height. A lumbar pillow attaches to your current chair, so you can add support without buying new furniture.

When can you expect benefits from using lumbar support?

• You spend a lot of time sitting. Whether it’s a full workday, a long study session, or working on creative projects at home, your posture can get worse, and your lower back muscles can get tired.
• You feel mild lower back discomfort after sitting. The right lumbar support can ease end-of-day pain and help you sit more comfortably without having to move around much. If your pain is sharp or spreads to your legs, see a professional first.
• Your chair doesn’t fit your body well. People who are shorter or taller than average often find regular backrests uncomfortable. Lumbar support lets you adjust the fit, so your spine stays in a more natural and comfortable position.

How to position your lumbar support

Sit back so your hips touch the back of the seat. Place your hand on your belt line and move it up until you find the deepest curve in your lower back. This is where the thickest part of your lumbar support should be.

Tip. To check the position, if the support pushes against your ribs, it’s too high. If it presses on your belt, it’s too low.

What if your chair has no built-in lumbar support?

You have 2 choices:

• A shaped lumbar pillow with straps can hold your back in the right position without making any permanent changes.
• Consider upgrading your chair. It’s really worth it! If you're not sure what makes a chair ergonomic, learning about them is a good place to start. Try to find one with adjustable height and depth.

When lumbar support isn't the right fix

Well, lumbar support doesn’t fix every problem. If it’s set up incorrectly or too hard, it can actually increase pressure and make you move around more. Some people feel better with a flatter backrest and more room to move, so think of it as one option among many, not a substitute for moving and having a well-organised workspace.
