Official Description: Sit comfortably for hours while quilting, sewing, reading, driving, and more. The Gypsy Sit Upon Can be used on hard or soft chairs, recliners, car seats or anywhere you sit for an extended period of time. This softly inflated flexible disc acts like an exercise ball - preventing fatigue and reducing pressure on the tailbone. Relieve lower back pain, strengthen your core muscles, and improve your posture the easy way. The nubby texture allows cool air flow and promotes improved blood circulation. Durable purple rubberized material remains soft and pliable. One size fits all!
Notes from Marsha: Not only is this good for people who sew, it works great for any person who sits a lot or uses a wheelchair. The first time I put this on my sewing chair, I immediately felt relief in my lower back. The side shown is the side with the highest bumps. Sort of like those bumps on the massage sandals of the 1970s. The other side has "barely" bumps.
