The Float-Eh 13.5' x 6' x 1.65" water mat is the second largest mat in our collection. The mat consists of 3 layers of foam equaling 1.65 inches of thickness (30% thicker than the average water mat), allowing for maximum buoyancy. While this mat can hold approximately 1200 lbs of dispersed weight, we recommend it for 3-5 adults or plenty of kids. This mat is perfect for people looking for some extra space to lounge but aren't planning to have the whole lake over. We're pretty sure you'll be hanging out on your floating mat until the sun goes down.
