The Classic chair was founder Claus Lundsgaard's idea of an ergonomic work chair without backrest and armrest. A chair that forces you to sit actively while also supporting and maintaining a healthy working posture that shapes the body and forces it to sit correctly.

The key principle behind the Classic chair is to put you in control when you sit down to work. 

It has a lightness that doesn't restrict you when you want to move around. Your arms, legs and shoulders can move freely. The active sitting posture improves your circulation, which benefits both your body and your concentration.

The Classic chair is a natural choice for anyone wanting to give themselves and their employees an ergonomic tool that supports a healthy working environment. With 30+ years on the market, this classic design has given so many people a better working day and an active sitting posture at work. The smooth-running wheels make it easy to move around on. The stepless raising and lowering function quickly and easily helps you height-adjust the chair.

The cover on the Classic chair is removable. We recommend artificial leather or microfibre, both machine washable at 60°. Read more about the fabrics under Material guide.

Why choose a chair from Dynamostol?

You have to because..

The seat is specially designed to keep your pelvis and spine straight so you don’t slouch as you would do in an ordinary chair.

The chair helps all the central muscle groups to have full mobility. It might take you a few weeks to train your back muscles, but it is worth the effort, and for every day sitting on your chair, you will feel that you are getting stronger and stronger in your core muscles.

The core muscles, also called the body's trunk, consists of deep muscles that support the spine and pelvis, ie. primarily the muscles around the abdomen and back.

Sit Strong

A strong body trunk is the whole foundation for virtually all the movements you make in everyday life and it has a huge impact for your well-being. Without strength in this part of your body you will collapse in the back, get a bad posture and the possibility of getting other problems is huge.

And there are more positive consequences. Your blood circulation improves and your ligaments work optimal. When you sit on a chair from Dynamostol, the diaphragm is more relaxed, giving you a better breathing. Because your upper body can move more freely, you get rid of them usual strains of shoulders, arms and neck.
