For a highly maneuverable power wheelchair in an attractive package, look no further than the Invacare Nutron R51 power wheelchair. This exciting model features dependable rear-wheel drive, enabling it to easily negotiate obstacles inside and outside the home. The electric wheelchair folds for easy transport when your active lifestyle takes you on the road.

What Makes This Different
The Nutron R51 is a highly configured powerchair which enables you to customize it for your needs. Choose from a variety of seat widths and depths, back heights and armrests. You can even choose to have one full length arm and one desk length arm so that when the controller is added the arm isn't too long.

Why We Like It
The Nutron R51 has quality components and the 5-Star In-Home Premium Service to support your needs. This service plan covers warranty parts and labor as well as common wearable parts like arm pads, casters and tires.

Measuring Guide

View Detailed Measurements
Seat Depth1
Measure from the most posterior point of the body to the inside of the knee, minus at least two inches. Some prefer more leg overhang to make room for their hand when lifting their leg.

Back Height2
Measured from the seat base to the top of the chair back. Power wheelchair riders need upper back support, particularly for the moment of initial acceleration.

Hanger Angle3
Determines how far the toes extend away from the body, measured from the horizontal. A tighter angle allows the electric power wheelchair to turn around in less space. Depends in part on ability of the knee to bend towards the perpendicular.

Seat Width4
Determined by the widest point of the body from knee to hip, plus an inch to ensure room to move. Consider bulk of clothing, particularly a heavy winter coat, if relevant.

Front Seat to Floor5
Measure the leg from the back of the knee to the sole of the foot. Then subtract the thickness of the cushion when it is compressed. Next, add a minimum of two inches for footrest clearance. Electric power wheelchairs are almost never foot-propelled by the user - so excluding the additional two inch footrest height for propelling is very rare.
