Great support & much less pain!
I've been dealing with back problems for many years.  Then, I got  bursitis in my left hip.  Sitting for any length of time was a problem, and I was about to get a gel seat or some such thing.  However, my physical therapist said I'd be more comfortable if I got something to keep my back in a more upright position.  He was right.  Luckily, I got this and am thoroughly delighted with the comfort I now have even on very long rides.  5 stars!
