Stand and sit are basic gestures of any bodied person. It can be barriers to support aging people at home, but also to enjoy public space. With a normal chair, the movement to sit involves accepting an imbalance that may be insecure. 

Upper position - the user is well sustained by the seat and backrest of the seat

Also, our seat welcomes and supports the movement and rhythm of the person sits. 

Interim position  - going down movement

The handlebar allows a sense of security because the user can stick to it. 

Lowest position - Perfect position for reading or having a rest

Interim position  - going up movement

When the person gets up, the seat sustains throughout the movement and relieves its efforts in carrying the weight of the body.

Upper position - the user is well sustained by the seat and backrest of the seat

The handlebar then stabilizes the return to standing position.
