This backrest really helps me to keep my back in a correct posture position. I am trying to do the Gokhale method but their chair support cushions were on backorder so I was looking for an alternative. These seem to have the same idea, to keep you from sitting with a rounded back, but instead to keep the pelvis tilted forward and the spine stacked on top of it. The cushion was easy to attach to my desk chair at home and the one at work. I’m even considering trying it in my car! My back doesn’t get nearly as tired while sitting at my desk all day as it did without this support, so it’s well worth it. ..More
