This orthopedic foam seat cushion by Aylio will add comfort to your chair, bench, car seat, plane seat, floor, or wheelchair. The rear cutout provides back pain relief by reducing pressure on the tailbone. Meanwhile, the ergonomically designed contour shape of the pillow promotes healthy weight distribution, posture, proper spine alignment, and superior comfort. Most importantly, it will not flatten out like other cushions because it uses the highest quality comfort foam for optimal support over long stretches of time. These claims are backed by the manufacturer's lifetime warranty! The velour cover is machine washable and can be removed using the zipper for easy cleaning. The cushion measures 18 x 14 x 2.5 inches.</br> </br> <b>Recommended for:</b> </br>Pain or numbness from sitting for long periods of time </br>Road trips, long flights, seated desk work </br>Extra cushioning for uncomfortable office chairs </br>Padding for a hard surface (e.g. wooden chair, bench) </br>Bruised, fractured, inflamed or broken tailbone </br>Healthy posture and proper spine alignment </br>Herniated, bulging, slipped or prolapsed disc </br>Pelvic pressure and hip pain relief </br>Pregnancy or labor-induced coccydynia
