Abstract
A chair with seat and backrest that oscillate in a synchronized way, comprising: a base structure (14); a backrest-supporting structure (26) articulated to the base structure (14) about a first transverse axis (A); a seat-supporting structure (44) which is mobile with respect to the base structure (14) in a way synchronized with the movement of oscillation of the backrest-supporting structure (26); and elastic means (24) tending to counteract the oscillation backwards of the seat and backrest. One rear part of the seat-supporting structure (44) is articulated to the backrest-supporting structure (26) about a second axis of oscillation (B) parallel to the aforesaid first axis (A), and one front part of the seat-supporting structure (44) is connected to the base structure (44) by means of at least one articulation element (50).
