The Aquamentor Swiss Cheese Foam Floating Mat is a versatile, durable aid for swim lessons and pool fun, crafted since 2013 by Aquamentor, a second-generation family business founded in 1983. Constructed from high-density polyethylene foam, this mat ensures buoyancy and longevity. The mat is also great for creating 'waterfall tunnels' to have kids walk under and get them used to having water splash on their heads and faces. Designed and manufactured in the USA by lifeguards and swim instructors, it's ideal for teaching swimming or recreational play. Swim with confidence with our Swiss Cheese mat!
