Have you tried a Kneeling Chair? Many chairs can be comfortable but to sit on one all day you need an especially comfortable chair. Try a Kneeling Chair and see the difference! It does feel a tiny bit strange to begin with. Your pelvis tilts just like you are standing. You rest the weight on your buttocks and shins. Your spine still has that natural curve. Getting in and out of the chair takes a few goes to get used to also, but the extra energy you feel and the benefits for energizing your entire spine are well worth it! Why not try a Kneeling Chair. You will love me for it!
