Good posture goes a long way in promoting your spine health and alleviating severe back pain issues. A good quality seat pillow or cushion is a great way to promote blood circulation to your legs and prevent issues like lower back pain, buttock pain, sciatica, coccydynia, hip pain, etc. Seat cushions help distribute pressure evenly and take off the stress from the tailbone that may cause severe back pain, which makes it difficult to sit for long periods. The Ergo21 seat cushions are a good option as they feature the advanced LiquiCell technology that improves your blood flow and lets your body glide. Choose a highly functional, versatile, and portable pillow and improve your posture.
