Cait says this should be called “Happy Buns,” rather than a portable get seat.

This cushion weighs just 2 1/2 pounds and folds in half to carry. The manufacturer says it relieves pressure inherent in long periods of sitting and helps to prevent or lessen back strain and blood vessel and capillary constriction.

The center groove eliminates pressure on the tailbone and the surface slopes slightly forward to encourage proper pelvic posture for correct lumbar curvature.

Cait wants a “Happy Buns” for the car, hard restaurant seats, uncomfortable bleacher seats and long trips on plane, trains and buses.
