I have arthritis and lower back pain and tend to slouch when I type. The Nada-Chair holds me tight and firm; it doesn’t allow me to slump. When I go home, my back doesn’t hurt. It makes the world of difference. I love it
Best strain and tension innovation chair that help with back pain to correct bad posture. The best brace with lumbar support you can buy. No ordinary office chair for upper and lower spine slouch correction. The wearable chair with for cars, kayaks, home office computer desks that NASA astronauts use as a pillow with pockets. The original, most successful design you may have seen as the best invention on Kickstarter that raised over a million dollars called BetterBack as seen on SharkTank.
