The Granstand III's modular, growth-capable design allows it to evolve with the user, making it the ideal long-term investment in standing technology.

It can be designed for kids as well as adults, and it can function as either a completely manual or fully hydraulically assisted standing device.

Standing without lifting:
Standing in the GS3 is simple. Set the knee-pad system and tray height with simple tool-free adjustments, making sure everything fits snugly. Simply slide the sling behind your hips and pull it on with our innovative pull-to-place tabs. Once the sling is on, wheel up to the system, place your feet in our shoe holders, and secure the sling to the lift arms. Pump the hydraulic unit to start the lift, then keep pumping up until the hips are properly positioned for optimal weight bearing. Hip extension can be as mild as 5-15 degrees.

FAQs
There's no need to lift or transfer the person separately. This stander uses a pull-to-place sling system that lifts the user directly from a wheelchair or seated surface, making it safer and easier for caregivers and reducing the risk of injury during transfers.
Yes, it's designed to grow and adapt as the user grows. The frame adjusts for height, and key components like footrests, knee supports, chest pads, and trays can be repositioned in depth, height, and angle—eliminating the need to replace the unit as the user matures.
The Granstand III features a narrow expandable frame (as slim as 27.5" wide), which fits through most standard doorways. The chair can roll into the stander directly, which means it doesn't take up much floor space—perfect for tight rooms or home environments.
