An improvement in an ARMCHAIR WITH SEATLIFT, as patented in U.S. Pat. No. 5,816,655 designed for a disabled person, or a person with weak legs, the armchair having a seat able to move vertically up and down in the frame of the armchair from a normal seating position to a position flat on the ground, the improvement being: making the armchair automatically mobile and automatically immobile when desired, by attaching wheels to the armchair in such a manner that the armchair automatically becomes mobile by making the wheels automatically become in contact with the ground when the seat moves to it's upper position, and automatically making the seat become in full frictional contact with the ground when the seat is in it's lower position, thereby facillitating the transfer of a person, fallen on the ground, safely onto the seat, without the seat tending to move away from the person during the transfer.
