Overview of the Pronto M31

The Invacare Pronto 31 is the newest, budget-friendly addition the Pronto family. It comes with a comfortable 18" captains seat with 360° rotation and 45° of adjustability, full length armrests that are height adjustable, flat-free tires, a push-button style seat belt and flip-up footboard. The Pronto 31 has compact front-wheel drive while featuring simple handling, durability, and comfort all in an ultra-sleek design.

What Makes This Different
The Pronto 31's compact size gives it a low profile and also makes it easy for tight turning, ideal for in-home use. This sleek design is available in two new colors, Blue Mist and Black Fog. The Pronto 31 also features a durable shroud with tool-less removal for easier access to the battery. 

What You Need To Know When Ordering

Our White Glove Delivery option includes the set-up of your power chair; however comfort adjustments, like foot rest height, will need to be done by the caregiver or user.

Measuring 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 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.
