The Hardrock is a highly durable and sturdy chair, specifically designed for children to adults who may engage in repetitive rocking. It provides moderate postural support, making it well-suited for both school and home settings. Recognizing the challenge of engaging children with complex learning needs in educational and daily activities, the Hardrock offers a positive, secure environment that promotes learning.

This chair incorporates an anti-thrust system and anterior pad to ensure secure postural management within well-defined boundaries. For children who display sideways motion, additional thoracic supports and stabilizers are available. The Hardrock includes several new standard features, such as a low back, fully slotted design, a standard 2-point lap strap, anti-thrust cushions, and a ski transporter base, all available in a vibrant blue color. These enhancements make the Hardrock an ideal choice for both support and functionality.
