Patients with recurrent or chronic lower back pains are tested and trained with the use of the Flexchair, a comfortable and dynamic seat. The Flexchair increases strength, enhances performance in sport and work, and reduces employee sickness absence. The Flexchair activates and stimulates dynamic movements, and contributes to the optimization of body-balance. The Flexchair was developed for people who aim to pursue a healthy and sportive lifestyle. Experience how sport- and work performance improve, and don’t give lower back pains a chance.
