For Sling Seat

Tension‑Adjustable Backrest

Adjustable Backrest for Power Wheelchairs—Transform Sling Seat into Personalized Comfort.

Who says power wheelchairs must compromise with fixed backrests?
Specifically developed for Karma’s Sling Seat, this adjustable backrest brings premium manual wheelchair positioning technology to the power seating sector. Through multi-stage tension adjustment, it perfectly contours to the back, addressing the lack of support in standard backrests to ensure greater stability and comfort during long-distance travel.

Rear-Adjustable Backrest Engineered for Clinical Excellence.

The most precise support is determined the moment you sit down. Karma’s adjustable backrest features a rear-mounted strap system, allowing caregivers or therapists to fine-tune the positioning in real-time while the user remains seated. This ensures three key clinical objectives are met with ease:

– Pressure Redistribution: Loosen straps at spinal protrusions to increase contact area, allowing the area to fit snugly and redistribute pressure effectively.

– Anatomical Support: Tighten lumbar straps to create a customized “lumbar support” effect, maintaining the natural spinal curve and delaying fatigue.

– Consistent Rigidity: Overcome the sagging common in traditional upholstery; straps can be re-tightened at any time to ensure the backrest maintains the rigidity necessary for correct posture.

For Users with Kyphosis

After Adjustment
Through multi-stage tension adjustment, the backrest contours perfectly to the user’s unique spinal curve.
This evenly redistributes back pressure and allows the user to sit fully back in the seat. By significantly improving support for the lower back and thighs (as shown in the green areas), it enhances overall stability and ensures a personalized, comfortable experience even during long-distance travel.
