Overview of the Sentra HD 450

Overview

The Sentra HD 450 is built to last! If you have been searching for a wheelchair that caters to a clientele who desire a higher weight capacity, the Sentra HD 450 is the wheelchair for you!  The spacious 20" wide seat is built with reinforced vinyl upholstery that remains supportive, even after extended use.  This chair comes standard either desk length or full length armrests that can be removed for transfers in and out of the chair.  Desk length armrests allow the user to sit at a comfortable distance from most tables, while full length allows the user to maximize arm support. The Sentra HD 450 comes equipped with heavy duty, aluminum footplates that offer maximum support.

Why We Like it 

The Sentra HD 450 from Drive Medical is the ultimate heavy-duty wheelchair. It 's reinforced gussets at all the weight-bearing joints, dual crossbraces and heavy-duty casters; allow this chair to hold up to 450 lbs!. The upholstery is reinforced to keep it from sagging after extended use. It also has heavy duty, flat free, 8” front casters that are adjustable in three positions to ensure your ride is adjusted to your liking. The crossbraces that connect the frame allow the chair to be collapsed to a mere 12.5" wide, for easy storage.

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.
