A seating unit that includes a seat-lift assembly adapted to move the seating unit between a closed and a seat-lift position is provided. The seat-lift assembly includes a drive linkage mechanism, and a lift linkage mechanism. The seat-lift assembly is attached to a seat linkage mechanism that includes a seat-mounting plate, a base plate coupled and a linear actuator for automating adjustment of the linkage mechanism. In operation, the drive linkage mechanism is moveably interconnected to the base plate and adapted to independently raise at least a first portion of the seat frame with respect to the base plate, the first portion being raised at a first rate, and the lift linkage mechanism is moveably interconnected to the seat-mounting plate, and adapted to independently raise at least a second portion of the seat frame with respect to the seat-mounting plate. |
