Abstract

An adjustable chair comprises a seat portion (8), a seat back portion (3) and support means consisting of two bent piece of rod (1) welded to forwardly extending rear frame members (2) and short welded posts (5). The seat and back portions are both movable relative to the support means and are linked together so that upward movement of the seat portion results in rearward movement of the back portion, and vice versa. The chair may also include a desk or table portion that may be swivelled about a horizontal axis. A second adjustable chair has a base frame 20, 21 comprising a pair of upwardly and rearwardly extending frame members onto which a seat back 26 is telescopically mounted and a pair of upwardly extending frame members onto which a seat portion 25 is telescopically mounted. Where they intersect, a linking mechanism is provided, for example two toothed racks 34, 38 that mesh with one another to ensure that the back and seat portions move together, either to move the seat back upwards and rearwards as the seat portion is moved upwards and forwards or vice versa. A locking mechanism may hold the seat at the desired size.
