Abstract:
A base for a seat or chair comprising:a chassis; a landing provided on the chassis; a carrier slidable in a first direction along the landing, the carrier being adapted to support, or capable of supporting, a seat or chair facing, or able to face, in a second direction which is at about 90 degrees to said first direction; and a carrier braking means having a friction material that is movable towards and away from the landing, the braking means being such that the carrier can only be freely slid along the landing when the braking means is released, the braking means being releasable by the weight of an occupied seat or chair that serves to move the friction material away from contact with the landing and thus release the braking means, which is otherwise adapted to cause the friction material to remain in contact with the landing.
