Karma SME — Manual Wheelchair with Power Standing Function
How to Adjust SME
Tailored Comfort, Exceptional Support
3-Stage Seat Depth Adjustment
Achieve the perfect fit for any leg length. Proper seat depth ensures the hips are fully supported by the seat surface, providing the most stable pelvic alignment and foundation.
Adjustable Tension Backrest
Featuring multi-stage heavy-duty Velcro straps, the backrest contours to the natural physiological curve of the spine. By supporting a collapsing torso, it reduces the risk of scoliosis or pressure sores caused by poor posture, delivering a secure and “wrapped” sensation.
Ergonomic Flip-Back Armrests
With 5 levels of height adjustment, these armrests are designed for versatility. They can be flipped back completely to create a barrier-free space for lateral transfers, significantly reducing the physical strain on caregivers.
Precision-Angle Footplates
Offering 4 height settings to accommodate different leg lengths. For users with high lower-limb spasticity or foot inversion (clubfoot), SME provides precise angle micro-adjustments. This ensures the footplate aligns perfectly with the pressure points of the sole, minimizing localized pressure, preventing foot injuries, and making standing therapy more comfortable and sustainable.
Exclusive Safety Design
Four-Point Stability System
When in standing mode, the system automatically engages four contact points with the ground. By expanding the support base from a “point” to a “plane,” this system effectively counteracts the shift in the center of gravity while standing. This ensures the wheelchair remains rock-solid and shake-free during any rehabilitation or stretching exercises
Adjustable Knee Support
Featuring stepless adjustment for depth, width, and angle, as well as customizable height. This system provides a firm foundation for the lower limbs, preventing the body from sliding during standing. It is fully removable in a seated position for unobstructed daily mobility. An optional knee support cover is also available for enhanced comfort.
Emergency Descent Button
Safety is our priority. In the rare event of a controller malfunction, the dedicated emergency button allows for a safe, manual descent, ensuring the user is never left stranded in a standing position.
Upgraded Controller
Experience intuitive control with an easy-to-read battery indicator. The upgraded interface supports direct plug-in charging, making daily operation more effortless and user-friendly.
