The Pressure Relief Ring Cushion relieves pain in the coccyx by distributing the weight more evenly through your buttocks rather than through your spine. The cushion is made with breathable foam with a washable cotton cover so it is perfect for everyday use. The practical size is ideal for sitting at home or in the office. The cushion is also perfect for sufferers of piles and prostatitis as it relieves the pressure and pain on the delicate anal and perineal area.
