Best cushion out there!!
I've tried several very expensive cushions through the years.  My last one I really liked, but decided it's time for a new one after using several years.  I retired it to my car!  After much research, I decided to go with this Royal Purple cushion.  OMG...difference of night and day.  I sit for many hours while working at my desk and this is the best thing I've ever used.  I have to use a cushion for low back pain, hip, and tailbone pain.  This does the trick and I'll be buying one for my dad, who also suffers from same issues.
