Patent abstract
An air mattress has a resilient front panel, an opposed rear panel and at least one interior panel extending therebetween dividing the mattress into ball and strike chambers. A ball air valve attached to the rear panel at the ball chamber activates in response to a predetermined pressure increase in the chamber occurring in response to deflection of the front panel at the ball chamber. A strike air valve attached to the rear panel at the strike chamber activates in response to a predetermined pressure increase in the chamber occurring in response to deflection of the front panel at the strike chamber. Signaling devices alert when a strike or ball air valve activates informing a user whether a pitch is a ball or a strike.
