Thomashilfen Hercules Small – Highlights

The headrest adjusts in both width (up to 3.35″) and height (up to 1.18″) to match your child’s anatomical needs and provide tailored support. This helps maintain head control and midline orientation, even during longer car rides.

Quick and tool-free back angle adjustment using red release clamps enables caregivers to easily reposition the seat for therapeutic alignment or comfort during travel.

The included crotch pad reduces belt buckle pressure on the sensitive lower abdomen and conceals the harness buckle for added comfort and security.

Infinitely adjustable seat depth (up to 6 cm / 2.36″) ensures a perfect fit as your child grows, helping maintain proper leg positioning and pressure distribution.

The Hercules Small folds easily into a compact, travel-friendly format with minimal effort. This lightweight, portable design is ideal for families needing flexible car seat solutions or frequent vehicle transfers.
Hercules Small: swivel and tilt function
With the integrated swivel base, the Hercules Small can rotate toward the vehicle door for easier transfers. Caregivers simply press the red trigger to rotate the seat toward the open door—ideal for children with limited mobility or for caregivers needing ergonomic access.
The tilt-in-space function assists children with reduced upper body control or hypotonia. It allows the seat to recline in 2.5° increments up to 10°, helping manage tone and reduce fatigue during longer trips.
