Rest your hand. Go where you're going.
The mushroom knob gives you a wide, domed surface to drape your hand over instead of grip. Your palm rests on top, your hand's own weight does most of the work, and steering becomes a lean rather than a squeeze.
Good for weak grip, fatigue, pain, tremor, or any day where holding onto something small for a long time is more than you want to ask of your hand.
The details:
- Fits power chair joysticks with a smooth pin (not compatible with threaded-pin systems like Edrive). Two sizes are available:
-
Compact Fit: OAS Air Pro & Air Carbon. Fits joystick shafts about 5–6 mm.
-
Standard Fit: OAS Air Ultra, Permobil, Quantum & more. Fits joystick shafts about 6–6.5 mm.
- Not sure? Measure your joystick shaft with a ruler or calipers, or reach out and we'll help you pick.
- Wide domed cap with a comfortable contact surface
- Durable PLA — smooth finish, rounded edges
- A rubber o-ring is embedded in the print to grip the shaft for a snug press-fit, no glue or tools needed
- Swaps back to your original handle any time
- Available in your choice of color
- Premium colors include multi-color and metallic finishes.
This is an aftermarket accessory, not a replacement for equipment fitted by your seating clinic or OT. If you're unsure whether a different handle style would help, ask them — they can usually let you try one.
