The story

of Dynamostol

What do you do when your back pain is so severe that you can't sit down?

When pioneer Claus Lundsgaard, Dynamostol's founder, suffered such severe back pain that he could only stand up or lie down, he was inspired to design a chair that could change the concept of 'sitting'.

Claus already had a nice office chair in a smart design, and he liked it, but it was big and cumbersome and it kept him positioned in the same static sitting posture for 8 hours a day, 5 days a week, which led to periods of unbearable back pain.

Claus had to sit down as part of his job. So he realised that he had to find a solution that would give him a more active and dynamic sitting posture, as he had noticed that his back pain decreased as soon as he was active and moving.

At the age of 55, he began developing an ergonomic chair, the Classic, which gave him an active sitting posture without straining his back when sitting down. The Classic chair became a light and elegant chair that met Claus' need to sit actively. He also found that he had more energy, because his blood circulation improved thanks to the more active and dynamic sitting posture.

At the beginning of the 1990s, Claus contacted world-renowned designer Nanna Ditzel, and asked her to help develop an ergonomic work chairNanna Ditzel welcomed this assignment and went on to design an elegant and functional chair based on the saddle chair principle. She decided to name the chair InCharge, with reference to the idea that people who used the chair would feel in control and in balance.

Innovation and caring for others

Claus thought that he couldn't possibly be the only person to suffer from pain in the musculoskeletal system caused by too many sedentary hours spent in an office chair. He also predicted that many people would suffer from back, neck and shoulder pain in the future, due to poor sitting postures. So he began designing a chair for all those industries where he could see that people were challenged by poor working positions, such as dental clinicshospitals and laboratories. but also staff in day care institutions and care homes og til rehabiliteringspersonalet.

Claus’ mission was to give everyone the opportunity to prevent pain in the musculoskeletal system by sitting on a light and functional chair. Claus set up a business selling ergonomic chairs to people who wanted to stay active while sitting down. To date, the company has sold more than 100,000 chairs to people who want to have a healthy and active sitting posture.

Today, 2021, Claus is 95 years old, and is still going strong. This makes him a living example of the fact that it pays to think about how to keep your body physically active, even in situations where you would normally be passive.
