<p>A chair comprises a backrest, a seat, a supporting structure for supporting the backrest and the seat, and a base support. The supporting structure, the seat and the backrest are each pivotably mounted to permit the supporting structure, the seat and the backrest to each tilt over a predetermined range. This allows the chair to move into and out of a reclined position. The seat is free to pivot over its predetermined range relative to the supporting structure independently of a tilt of the supporting structure. The pivoting backrest and the pivoting seat are intended to encourage dynamic sitting.</p> |
