The Class Champs Gym is a one-of-a kind free-standing system providing vestibular therapy to multiple users. Class Champs asked therapist and educators their opinions and after two years, this gym is a reality. Made of high-quality, pressure treated wood, it connects to any single swivel or double standard attachment. Easily attaches in minutes with just a single wrench. It's still possible to close the door after setup. Attachments are sold separately so it's possible to pick what is best for a specific clinic: rope ladder, platform swing and net swing.
