A chair has a backrest handrail 11 which can recline about a pivot 14, and extensions (16, fig 7) to the handrail 11 that are pivoted 22 to a seat 20, the extensions changing length as the chair reclines whist the seat shifts forward towards a lying flat position. The backrest has back strips 12, and a plug head (13, fig 5) close to each end of the handrail enables assembly to a push chair. Supporting plates 32 joined to the handrail and pivot connected to movable arms 34 are each internally fitted with a segmented clasp mechanism controlled by a grip 31 on the handrail rotating an inclined cam surface. The extension rods 16 can be air or oil pressure rods.
