I know this is a lumbar support, but it have proven invaluable to me for thoracic spine help. I suffer from degeneration of my spine from C1 – T12 (in other words, everywhere EXCEPT my lumbar spine). Sitting upright in a regular chair for any length of time becomes excruciating very quickly. I decided to try this support pillow on my middle back, as stretching that portion of my spine relieves pressure on the nerves and therefore lessens my pain. It worked! I am able to use the strap to place the support exactly where I need it in my chair to be able to sit at my desk for loner than 5 minutes at a time (I’ve made it up to 20 now!) The curvature of this support pillow elongates my thoracic region enough to spread my vertebrae and relieve nerve pressure, and this pillow truly has been very helpful for me. I was skeptical that the memory foam would not provide the support I need, but it is doing a great job. I’m really happy with it! ..More
