A stairlift is a seat that moves along a rail fitted to the stairs, transporting a person up and down the staircase while seated. It is ideal for individuals who can transfer independently from their wheelchair to the stairlift seat. A platform lift, on the other hand, is designed to carry a wheelchair and its occupant, providing a platform that moves vertically between floors. Platform lifts are suitable for both wheelchair users and those who cannot transfer to a stairlift seat, offering a versatile accessibility solution for multi-level buildings.
