Stratum Lift from Stannah | Our Stratum lift is ideal for wheelchair users. When space is tight we have a homelift for wheelchair users that is only fractionally larger on the outside than on the inside and the Stratum Longer Wider model can accommodate all category A and B wheelchairs. For those who do not use a wheelchair we offer the Stratum Compact — a seated model that is two thirds the size of our standard model.
