Overview

The Hercules Prime Special Needs Booster Seat is a forward-facing rehabilitation booster designed to safely transport and properly position users weighing 40–176.4 lbs and measuring 51.1–70.9 inches tall. Intended for individuals with physical, neurological, or cognitive disabilities, the seat installs using a standard 3-point lap and shoulder vehicle seat belt and provides significantly more support than a traditional booster when additional trunk, hip, or head stability is required.

Built to grow with the user, the Hercules Prime features infinitely adjustable backrest height, seat depth adjustment, and an adjustable back angle to ensure proper fit as body size and needs change. A 5-point non-load-bearing positioning harness with shoulder pads and chest clip helps maintain upright posture, while the wide seat base supports larger users comfortably.

What Makes This Different

What sets the Hercules Prime apart is its ability to support larger and heavier users while still offering fine-tuned clinical positioning. The seat accommodates a shoulder width of up to 20.1 inches with optional shoulder guides, and can be customized with lateral trunk supports, upper body guides, leg guides, abduction block, footrest, and anterior support options. These components allow clinicians and caregivers to adapt the seat to complex postural needs over time. 

Why We Like It

What we like most about the Hercules Prime is its long-term usability for growing and adult users who have outgrown pediatric car seats but still require structured positioning. The wide adjustment range, high weight capacity, and swivel/tilt features make it a practical solution for caregivers managing transfers while maintaining safety and comfort over many years of use.

What to Expect When Ordering

When ordering the Hercules Prime Special Needs Booster Seat, the seat arrives pre-assembled with standard components included. Selected accessories ship with the order and are installed separately. The booster installs forward-facing using the vehicle’s lap and shoulder belt, with lower anchors or a stabilizing bow required for stability, depending on vehicle configuration.
