    More Information

    Available with a number of additional positioning options, the Rifton Medium R850 Hi-Lo Base Pediatric Activity Chair provides children with contentment in each position without compromising their safety. Made with caregivers in mind, its toolless adjustments reduce the amount of time spent on making adjustments to the activity chair. Additionally, adjustments can be done while the child is in the chair, further minimizing the time spent on adjustments and allowing for more time focused on therapeutic needs.

    For those with restlessness or anxiety, this Rifton activity chair supplies two options for the adjustable seat and back system: standard or with a back spring. As an optional upgrade, the backrest spring provides children with the ability to bounce and rock, soothing and calming them before, during, or after therapy sessions. For times that the spring is not needed or desired, it can be locked.

    Made of durable materials, this hi-low activity chair comes with the choice of arm supports: armrests or forearm prompts. For added support and positioning, the forearm prompts are designed to provide the child with abilities that were once difficult to accomplish, such as utilizing a communication device on their tray. For simple support, the armrests are a great option for children that require additional trunk stabilizing and can be individually height adjusted.

    With the choice of six upholstery colors, each pad is constructed of polyurethane foam enclosed in healthcare-grade polyurethane-coated fabric, making them easy to keep clean. Their cushioning is built for preventing pressure ulcers, or decubiti, ensuring a comfortable user. For maneuvering the activity chair, it is equipped with four swivel lock casters that can either be moved in a straight line or around tight spaces with ease.
