Save your money!
This is more than a waste of $50.  Not only does it not help, but it actually makes it worse.  I have existing back issues and am now currently pregnant. I tried a different brand of gel cushion and it was GREAT but too large for my chair.  I returned it and ordered this one instead.....it actually causes me PAIN.  My butt is now sore all day from sitting on this cushion and my back issue isn't helped either.  Also it is small and scoots around....I constantly have to re-adjust. It flattens out into mush and the cushion looks like crap after 3 weeks use.  Can't return it.  Sometimes Amazon finds are great.....sometimes they aren't.  Save yourself the time you guys....this one is worse than not great.
