A booster with a positional harness made by Thomashilfen, a company with U.S headquarters in Sumner, WA.

Description

This booster seat features a positional harness (non-load-bearing), is relatively lightweight, and is highly adjustable to fit to various body sizes, shapes, and positioning needs.   
This booster MUST be used with a vehicle lap-shoulder belt.  The side wings can be adjusted in and out individually, the headrest adjusts separately, and the backrest can be raised using eight positions.   Several accessories are available to customize fit and function. May be used with Thomashilfen’s swivel base, which has a lock-out function and up to 10° tilt option, for ease of loading/unloading.
