We have tested the Flexi-Felt® chair leg cover simulating a 182kg (400 lb) person. After simulating the typical chair movements during a typical school day for 5 years, we were pleased to see that the Flexi-Felt™ was still good to go.
We then simulated a more typical 72kg (160 lb) student and proved that each of our Flexi-Felt™ models outlasts tennis balls 15 to 1 or more. The Flexi-Felt® was specifically designed with quality and durability in mind. It was engineered for classroom and institutional use, this is why it is so durable and effective.
Finally, we went on testing our chair leg cover simulating a regular 36kg (80 lb) elementary school child. So far the Flexi-Felt® has gone through over 200,000 translations (an incredible 10-year of wear) and it is still going. Amazingly, after such a long beating, it is still very soft on the flooring.
