More Information

Many children are prone to rocking back and forth and wiggling excessively when required to sit for extended periods of time which can negatively impact both their concentration and their performance; that's why the Hardrock Anti-Rocking Pediatric Chair was designed with anterior padding and an anti-thrust system, to help minimize this unwanted movement and simultaneously encourage better posture.

The Hardrock is available in three different sizes, each with a variety of adjustable components, to ensure the chair provides the best fit for each individual child. For taller children, the seat can be raised to increase its distance from the floor; the depth of the seat can also be adjusted to accommodate children with longer legs. Both armrests can be adjusted up and down and are closed-base to reduce sensory input and create an enclosed sense of security. The thoracic supports can be positioned at any point along one of the three vertical slots to accommodate the child. Each size of the Hardrock comes with a mobile base, 4-point Samba lap strap, and either a high or low back with this slotted upholstery.

Molded pelvic supports, alternate headrests, abduction pommels, and trunk supports are just a few of the available accessories designed to ensure the chair meets all the unique needs of the individual child.
