Karman S-Ergo 305 Patented Seating System
The S-Shape Seating System is a patented design by Karman Healthcare. It creates a seat that evenly distributes weight and pressure across the user's bottom and legs to help prevent pressure sores. Its stable surface prevents users from slipping forward, reducing the risk of users falling out of the wheelchair.
This transport chair features two seat widths:
- S-Ergo 16-inch seat wheelchair
- S-Ergo 18-inch seat wheelchair
Though the two options feature different seat widths, they both have a depth of 17 inches and a weight capacity of 250 pounds.


Antibacterial Wheelchair Cushion
This mobility aid features an AEGIS-treated antibacterial cushion that provides mild support and positioning. The AEGIS disinfection treatment protects against contaminating microbes such as viruses, fungi, and bacteria. Each seat cushion uses breathable mesh fabric to increase comfort and help prevent heat and humidity buildup.
Convenient Storage and Travel Features
The S-Ergo 305 weighs only 30 pounds for a lightweight product that is easy to carry. Its flip back armrests, removable footrests, and foldable design make the unit compact and simple to transport. The flip back armrests move back to make it easy to place the wheelchair at different tables. The polyurethane flat rear wheels use quick-release axles for easy removal. The rear wheels mount to different positions of the frame, which alters the seat height or overall stability of the wheelchair. Removing the wheels may be ideal for storing the unit in cars, closets, or other compact spaces.
