Back pain when working at a computer – where does it come from?

Learn the causes of back pain during sedentary work and find out how to improve comfort and posture at the computer.
Health 18 February 2026
Back pain caused by long hours of computer work is a problem that today affects not only office workers, but also pupils, students, and gamers. It usually starts with mild discomfort in the lower back, which over time can develop into chronic muscle tension, neck stiffness, headaches, and reduced concentration. The most common cause is not sitting itself, but a poorly designed workstation. The ideal desk height – the key to healthy posture

One of the most common mistakes is failing to adjust the desk to the user’s height. A desktop that is too high or too low forces an unnatural position of the arms and shoulders, leading to tension in the shoulders and neck.

The ideal desk height allows you to keep your forearms parallel to the floor and the monitor at eye level. The shape of the desktop is equally important—ergonomic cut-outs provide comfortable wrist support and better access to equipment. Such solutions are offered by KRL gaming art in the Aero and Ergo models.

A chair that supports the spine

The second pillar of a healthy workstation is a properly selected chair. An adjustable model with lumbar support and a stable backrest works best. The spine should be supported along its entire length, while the feet should rest comfortably on the floor. These details are what determine comfort during long hours of work.

Small additions – a big difference

Ergonomics is also supported by accessories such as wrist rests, lumbar cushions, monitor mounts, or keyboard trays. Sometimes just a few small changes are enough to feel noticeable relief and improved comfort.

Movement and breaks are just as important as equipment

Even the perfect workstation cannot replace movement. Sitting for many hours restricts circulation and causes joint stiffness, which is why it is worth standing up every 30–60 minutes, taking a short walk, or doing brief stretches. Height-adjustable desks are becoming increasingly popular, allowing users to switch between sitting and standing positions and relieve the spine.

Comfort today means health for years to come

Back pain does not have to be a daily reality. A properly adjusted desk, correct posture, and regular movement are simple steps that help protect the spine and improve quality of life. If you spend many hours a day at the computer, investing in ergonomics is an investment in your health.
