Most chair cushions do a mediocre job at supporting your backside. But they usually are bulky, get too hot, and have a hole cut out in the cushion to accommodate your tail bone. The Egg Sitter® support cushion supports your backside so well that you can sit on an egg without breaking it! Sit on the hardest surface and still feel comfortable. Egg Sitter® has a honeycomb design made of ultra-flex polymer that stays cool to the touch, allowing air to circulate. It collapses in on itself to absorb pressure points. Use on your chair in the dining room, in the car, and at the office. It’s time to say goodbye to sore muscles from sitting all day at your computer or lower back pain from driving long trips. Egg Sitter® includes a non-slip, washable cover. For optimal support, start sitting on an Egg Sitter® support cushion.
