Tumble Forms2 products have antimicrobial protection built into their coating, which works from within to help prevent or inhibit odors and premature coating wear caused by harmful microorganism growth. The antimicrobial treatment provides an added degree of protection that maintains cleaner, safer surfaces, and it won’t wash or wear off, so it continually works to help products last longer and remain fresher and odor-free. Tumble Forms2 combines innovative design with superior manufacturing to provide durability, functionality, and attractiveness. Designed especially for children and adults with special needs, these products offer maximum comfort and encourage peer interaction and positive patient/caregiver reinforcement while their versatile design allows therapists to creatively position clients. Made with a high-density, shock-absorbing foam that retains its shape even after long-term heavy use, and a unique, non-toxic, seamless coating that is flexible, durable, and resists cracking or peeling over an extended period. Not made with natural rubber latex.
