Description
The Drive Viper Jr. Pediatric Wheelchair is a real wheelchair sized for a child — not an adult chair made do. The 12 in and 14 in seats match smaller frames, the seat height adjusts on a dual axle as legs grow, and safety is built in rather than bolted on: flip-up anti-tippers are standard, and the armrest receiver is steel-lined and angled so the arm locks in correctly every single time. For families and pediatric clinics, it is the fit that makes daily mobility safe instead of approximate.
- Pediatric sizing: 12 in and 14 in seats with matching seat depths
- Dual axle — seat-to-floor adjusts from 15.5 in to 17.5 in as the child grows
- Flip-up anti-tippers standard, for rearward stability
- Steel-lined angled armrest receiver — the arm locks in every time
- Flip-back desk arms with padded nylon armrests
A Pediatric Chair That Fits Like One
Children are not small adults, and their chairs cannot be either. A seat that is too deep slides a child forward; a seat height that cannot adjust strands short legs or drags growing ones. The Viper Jr. starts at true pediatric dimensions — 12 in and 14 in seats with matching depths — and adjusts around the child: dual axle positions set the seat height between 15.5 in and 17.5 in, and the back height adjusts from 16 in to 18 in. The black powder coat is double-coated and chip-proof, because a child's chair lives a harder life than most.

Why Pediatric Fit Is a Safety Feature, Not a Size Option
Posture, reach, and stability all depend on dimensions an adult chair cannot shrink to. The Viper Jr. was engineered at a child's scale — and then made adjustable, so the safe fit lasts longer than one growth spurt.
- Sized for Children – Seats, depths, and hand rims proportioned to the rider.
- Grows With Them – Seat height and back height adjust instead of expiring.
- Safety Standard – Anti-tippers and a self-guiding arm lock are included, not upsold.
- Clinic-Grade Build – Double-coated chip-proof frame over carbon steel.
Manuals and Troubleshooting Guides
Frequently Asked Questions
What is the weight capacity?
250 lb at both seat widths. Drive's product page, specification sheet, and owner's manual all state 250 lb for the 12 in and 14 in chairs.
Which size should my child use?
The seat should match the child's hip width with a small margin: the 12 in seat suits smaller children, the 14 in gives more room. Seat depth matches seat width on this model (12 in and 14 in respectively), and the adjustable seat and back heights fine-tune the fit from there.
Are the anti-tippers included?
Yes — flip-up anti-tippers are standard equipment on every Viper Jr., at no extra cost.
How do I adjust the wheel locks?
Engage both locks before transfers, leaning, and elevators. Per the owner's manual, the lock shoe must embed the tire by at least 1/8 in when engaged: loosen the carriage-bolt nut, slide the clamp toward the rear wheel while the handle is in the locked position, tighten, and test the hold before use.
What maintenance does this chair need?
Wipe the polyurethane tires occasionally with a damp cloth and replace them if severely worn or cracking; inspect the front casters at least monthly per the manual and lubricate the stem and wheel bearings occasionally, tensioned so there is no play yet the wheels roll freely.
What warranty does it carry?
Drive lists a limited lifetime warranty for this model.
