Sliding Back Power Recline (SBPRS)
Back slides downward as it reclines, greatly reducing
shear. Excellent for those with skin deterioration or break-
down. Not pictured.
Up to 70 degrees of recline (some restrictions apply)
Adjustable linkage allows nearly 5” of sliding motion
Power Recline System (PRS)
Our Power Recline System is extremely durable
Up to 80 degrees of recline (some restrictions apply)
Greater strength and less complexity than
competitive systems
Optional Pushrod Linked Elevating Legrest available
Options available for users up to 700 lb
Power Seat Elevator 2 (PSE2)
Elevating seat increases user independence. The Power
Seat Elevator 2 raises the seat as much as 13”, typically
bringing the user's face to normal standing height. Even
more impressive, most users under 250 lbs can drive the
chair in the raised position.*
Up to 13” of elevation (some restrictions apply)
Can be combined with tilt, recline, and/or power
elevating legrests
Especially useful in the workplace
* Limited speed, operation on level ground, and good judgment
are required!
Power Tilt System (PTS)
Power Tilt System is extremely durable
Up to 50 degrees of tilt (some restrictions
apply)
Greater strength and less complexity than competitive

Power Standing System with 2 actuators
STS (seat-to-stand) actuator moves user from seated to standing
position and vice-versa
SA (standing angle) actuator adjusts the angle of the standing
position from about 30 degrees to within 8 degrees of vertical
In the seated position, the SA actuator controls reverse tilt. This
moves the user forward to access items in front of him and also
aids in transferring to and from the chair
Ability to drive at slow speeds when standing
Flip up foot board and knee support
Self-supporting flip up arms
can be moved out of the
way to allow unobstructed
arm movement
Can be combined with
Power Recline (PRS) or
Power Tilt (PTS) (some

A Reverse Power Tilt System provides user control of the angle between the
seat and the ground. The back of the seat tilts up from the normal driving
position, and the seat and back move together. This facilitates transfers into the
chair from a standing position and vice versa. Toggle switch control is
standard. Usually the tilt can be adjusted over about a 30 degree range. The
seat-to-back angle is fixed, usually at 94.5 degrees, though other seat-to-back
angles can be custom ordered. The arms move with the seat. Front rigging is
attached to the base of the chair and does not move with the seat.

Power Front Load (Latitude) System (PFLS)*
The Power Front Load System allows the user to extend the seat
forward and closer to the ground, thereby reducing the effective seat-
to-floor height. The arms and front rigging move with the seat. This
allows for easier transferring into and out of the chair and gives the
user the ability to reach things on the floor. Great for double amputees,
people with deformed lower extremities or who are short in stature.
Can be installed on the BOUNDER Plus H-Frame Power Chair.
