At the end of the evening, it's time to relax in front of a good TV program or a good movie.

We settle down in our favorite armchair thinking that the body is going to be recharged with vitality, but instead, the discomfort takes us, we squirm, we sit all crooked, we add cushions behind the back for a short moment of respite. But it's hopeless, impossible to concentrate on what's playing on TV.

The back of our favorite chair is either too stiff or too soft and the thought of throwing it out the window goes through our heads.

The solution! Buy a new one... But even the newer and more expensive ones have the same problem. The backrest doesn't support the hollow of the back.
