Unlike octagons and other shaped trainers, The Boulder® Handspring Trainer (U.S. Pat. No. 7,789,805) with its unique "single flat side" design ensures this product:

• Stands ready for use and automatically returns to proper position after each use
• Properly supports user throughout the full motion
• Begins rolling only when user correctly transfers weight
• Encourages user to “snap down”
• Does not prematurely eject user
• Never rolls over or on top of user
