A transfer seat assembly (100) comprising a generally planar support (110) for supporting a user, an anchoring bracket (300) for anchoring the assembly (100) to at least one structure (e.g. of a vehicle), and a coupling mechanism (200) for coupling the support (110) to the anchoring bracket (300). The coupling mechanism (200) comprises one or more adjustment mechanisms (210, 220, 230). One mechanism is a height adjustment mechanism (210) for adjusting the support (110) in a direction substantially normal to the 10 generally planar surface. Another mechanism is a tilt adjustment mechanism (220) for tipping the support (110) at an angle relative to the anchoring bracket (300). A further mechanism is an extension adjustment mechanism (230) for extends the support (110) away from the anchoring bracket (300). There is claimed separately an assembly with all three of tilt, height and extension adjustment, and assemblies with each of those adjustment mechanisms individually. The assembly allows a disabled person to get into or out of a car more easily.
