Description
The Strongback Heavy Duty brings Strongback’s patented posture support to a wider, stronger folding wheelchair. It has a 22″ wide by 19″ deep seat, a reinforced frame rated for 375 lbs., integrated drum brakes and 24″ quick-release rear wheels with ergonomic hand rims. Like every Strongback, the backrest is built into the frame to support the natural curve of the spine. The frame weighs 27.8 lbs. and the full chair weighs 39.2 lbs.
Most heavy-duty wheelchairs are built strong but uncomfortable, with a wide sling seat and back that sag and let you slump. Larger users often need posture support the most, because slumping puts extra strain on the back and shoulders. This chair gives you a high capacity and a supportive seat in one folding frame.
Key Features
- 375 lb. weight capacity on a reinforced frame.
- Wide 22″ x 19″ seat.
- Patented Strongback backrest with adjustable lumbar tension.
- 12° seat angle that keeps the hips back in the chair.
- Integrated drum brakes for dependable stopping.
- 24″ quick-release rear wheels with ergonomic hand rims.
- Swing-up anti-tippers and swing-away detachable footrests.
- Desk-length armrests.
Comfort for Larger Users
The Strongback Heavy Duty seat is angled 12 degrees so your hips settle back instead of sliding forward, and the curved backrest supports your lower back. Hook-and-loop straps behind the backrest let you adjust the support. Strongback recommends this chair for users who are over the 300 lb. limit of the Comfort line or who need more seat width than a 20″ chair offers.
Built-In Drum Brakes
Many standard wheelchairs use simple push-to-lock wheel locks that press against the tire. The Heavy Duty uses integrated drum brakes instead, which give more dependable braking for a heavier chair and rider. The angled push handles also give a caregiver better control when pushing.
Still Folds for the Car
Pop off the quick-release wheels and the frame weighs 27.8 lbs., which is light for a 375 lb. capacity chair. Folded, it measures about 31″ x 13″ x 35″, so it fits in most SUVs and many car trunks.

Using the Strongback Heavy Duty Safely
