Abstract: A walker or rollator has a first frame section (1) fitted with handles (6) and pivotally connected to a second frame section (2) such that the rollator can be collapsed. Stays (9, 11) extend between the frame sections (1, 2) and are pivotally secured in each respective frame section and which, in a locking position, maintain the rollator in the position of use. A seat surface (15) is, with a first edge portion, pivotally connected to a joint (13) which connects the stays (9, 11) to one another, and with a second edge portion supportable on support member (16) on the one stay (11) adjacent the joint connection (12) thereof with the frame section (1). The load of the user on the seat surface (15) influences the stays (9, 11) towards the locking position.
