Ypsilon’s most convincing feature is its innovative seating concept.
It adapts to the body of the sitter, follows his or her movements, and provides support without constricting.
It can be individually adapted to the size and weight of the user.
Because of its sensitive motion mechanism and extremely wide backward angle,
even tilting back in the lounge position becomes a viable working position where
the sitter’s eyes are focused on the screen.
The flexible backrest is like a sail.
Frameless and fixed only on the corner points,  it has a burred texture that encourages
pleasant air circulation.
The soft cushioning of the headrest and armrests and the patented ClimaSeat offer additional comfort
and create an agreeable sitting climate for extended periods.
