Patent ID: 10155130

Abstract:
A seating device for increasing use of a user's core muscles includes an adjustable air-filled bladder having generally flat top and bottom surfaces, and a significantly stiffer but resilient foam cover that fits over and matingly engages to the bladder. The cover is contoured, having both a central groove or recess that partially receives and accommodate male genitalia, and a raised ridge toward the front of the device to help keep the user properly positioned on the cover. The fluid-filled bladder is astable or wobbly, requiring the user to use his core muscles to maintain an upright, seated position, while the cover provides a comfortable contoured seat. The device can be used with an exercise device in which the user sits on the device, including on an abdominal exercise device, thus increasing both the abdomen strengthening action of the exercise as well as providing increased comfort for the user.
