Wheelchairs are a basic necessity for people with disabilities, especially people with physical disabilities. Although conventional wheelchairs have aided the mobility of people with disabili-ties, they are limited in scope due to physical exhaustion and health problems from sitting in wheelchairs for a long time. This research is important to develop seatback and cushion features for Health Electric Wheelchair Portable IoT-Based wheelchairs, for easy and comfortable mobil-ity for people with disabilities. The development of wheelchairs aims to reduce the negative im-pact of prolonged immobilization on people with physical disabilities. The development of this pad uses the Research & Development method. The result of this development of this wheelchair pays attention to ergonomic design by developing seatback and chair features for Health Electric Wheelchair Portable IoT-Based wheelchairs to provide safety and comfort when using wheel-chairs, especially physical disability. The development of cushion and seatback on wheelchairs can reduce the negative impact of immobilization on people with physical disabilities and is able to provide broad access for users to mobilize on wheelchairs and can adjust to the ergonomics of each user's body.
