Manuals, Literature & Videos


The Viper GT has been redesigned to feature a height adjustable universal length armrest. The armrests can slide back or forward to create a full length or desk length armrest. The seat now also includes a built-in seat rail extensions and extendable upholstery to adjust the depth from 16" to 18".

The Drive Viper Plus GT is designed for comfort, adaptability and transportability.  Padded nylon back and seat upholstery provide for a comfortable seating surface whether using the chair for just a few hours or all day.  A 300 pound weight capacity for 16", 18" and 20" seat widths or 350 pound weight capacity for 22" seat width make the Viper Plus GT accommodating to just about any body type.  A chair weight of 34.5-36 lbs. makes the Viper Plus GT convenient for transport. 

What Makes It Different
The Drive Viper Plus GT is the most adjustable lightweight wheelchair available at one standard low price. The adjustable seat rail extensions easily adjusts the seat depth from 16" to 18" and comes standard on all chairs up to a 20" seat width. In addition to an easy-to-adjust seat depth, you also get two quick-release axle positions allowing you to set the seat height at either 17.5” (for shorter users or those who propel with their feet) or 19.5” (for average to taller height adults).

Why We Like It
The comfort adjustments on the Viper Plus GT and light weight are the main appeal for the wheelchair. Being able to adjust the seat depth from 16” to 18” allows the chair to be adaptable to multiple users or varying seating preferences. Very few wheelchairs and even fewer lightweight wheelchairs offer an angle adjustable backrest.  The Viper Plus GT’s backrest can be adjusted from 5º to 20º. The quick release rear axles make it simple to remove the rear wheels and greatly decrease the amount you have to lift to place the chair in your vehicle when transporting your wheelchair. The Viper Plus GT comes standard with adjustable anti-tippers.

*Accessories will be shipped separately and it is the user's responsibility to install optional accessories onto their Viper Plus GT wheelchair.

Measuring Guide

View Detailed Measurement Guide
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 wheelchair back. Depends on how much upper back support is needed, and also affects freedom for the upper body to rotate.
Rear Seat to Floor3
Measurement from the ground to the rear seat edge. Relative to the front seat-to-floor dimension, this determines the rearward slope ("dump" or "squeeze") of the wheelchair seat.
Hanger Angle4
Determines how far the toes extend away from the body, measured from the horizontal. A tighter angle allows the wheelchair to turn around in less space. Depends in part on ability of the knee to bend towards the perpendicular.
Seat Width5
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.
Wheel Camber6
Angle of the wheel relative to the vertical. More camber improves stability and agility, but also limits ability to pass through narrow spaces. A typical daily wheelchair uses three degrees of camber.
Front Seat to Floor7
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. Do not add the footrest clearance if the wheelchair will be foot-propelled.
Footrest Width8
Measure from the inside of each legrest tubing the distance or desired distance between legrests.
Center of Gravity9
Measure from the front of the seat back post to the center of the rear axel.
Seat to Footrest Length10
Measure from the edge of the seat upholstery to the top rear of the footrest.
Backrest Angle11
Measure the the angle of the back post to the floor. Ninety degrees will be perpendicular to the floor, to approximate the angle from the back post to the seat, subtract two degrees from measurment for every .5" of dump.
