Greatest seat cushion out there!!!
I've been working as a  professional orchestral violinist for almost 30 years, and various areas of my back being in pain have become a way of life (try holding your arms up like you're playing a violin for 5 hours a day and you'll understand!!!).  I've tried at least a dozen seat wedges, back cushions and other supports to help me with my lower back pain.  I finally found and bought a Wondergel seat cushion, and for me, it has been a Godsend.  It boosts my height so I slouch less, and the way the material gives, I can move around without ever losing support.  It's really the best product of its kind on the market- well worth the investment.  As far as comfort goes, I jokingly say to people at work "I'd do an endorsement deal for this cushion- Wondergel, it's like sitting on a cloud!!!"
