A deckchair (80) is designed to be retained in erected position by means of selective engagement of its lower cross-bar (87) with one (88) of a plurality of spaced-apart channels provided in a bracket (83) fixed to each of the rear legs (84) of the deckchair. The plurality of spaced-apart channels each have an entry portion (20 to 22) and a transversely directed engagement portion (25' to 27') to ensure that the deckchair is unlikely to collapse accidentally. The invention is applicable to different kinds of furniture besides deckchairs, including sun loungers, folding tables and other folding furniture.
