Defender Max Booster

Description

Overview

The Defender Reha US Booster is a forward-facing special needs booster seat designed for children weighing 40–120 lbs and measuring 43.4–57 inches in height. Engineered as a Universal Restraint System, it meets and exceeds FMVSS 213 safety standards and is intended for use in vehicles equipped with a standard 3-point lap and shoulder seat belt. 

Built to provide superior postural control, the Defender Reha Booster includes a height-adjustable headrest, removable head, trunk, and hip supports, and a 5-point positioning belt with chest clip and shoulder pads. These features help promote an upright, stable sitting position while improving comfort and confidence during vehicle travel.

What Makes This Different

What sets the Defender Reha US Booster apart is its ability to support larger, growing children who still require positioning assistance beyond what traditional boosters offer. The seat provides a generous adjustable seat width, extended back and shoulder height, and a standard crotch strap extension to accommodate growth and improve pelvic positioning. 

Optional accessories—including swivel base options, short or long footrests with adjustable angles, seat wedge, abduction block, anterior support table, and seat depth extension—allow clinicians and caregivers to customize the seating system for each child’s specific needs and vehicle setup. The narrow overall footprint also helps preserve space for additional passengers or car seats.

Why We Like It

What we like most about the Defender Reha US Booster is how it bridges the gap between traditional boosters and more complex transport seating. It offers high weight capacity, excellent adjustability, and meaningful postural support in a design that remains practical for everyday family travel. The modular accessory system ensures the seat can adapt as the child’s needs evolve.

What to Expect When Ordering

When ordering the Defender Reha US Booster, the base booster seat includes the height-adjustable headrest, 5-point positioning belt with chest clip and shoulder pads, removable positioning supports, cup holder, small crotch pad, and crotch strap extension. Installation is forward-facing only and requires a vehicle with a 3-point lap and shoulder belt. 

Accessories such as swivel bases, footrests, wedges, and additional positioning components are ordered separately to match the child’s seating and mobility requirements.
