There may be no cure for sciatica, but with this cushion, who cares?
Yes, I have severe sciatica but I have been sitting on this cushion now for three hours and I haven't felt this comfortable in months.  There is a slight "massaging" sensation when you first sit down but the gel is naturally cool and that helps the soothing even more.  I'm tempted to try refrigerating it when not in use, if there ever comes a time like that.  I will be buying one for home, one for office, and one for my spouse.<br /><br />It's not cheap but you've already tried the cheap foam cushions and they soon compact in 10-15 minutes and you're not getting any shock absorption past that time.<br /><br />[Updated 12/09/2012]<br />Still happy with the product.  Agree w/others who would like just another inch or two in width, but its OK.  Spouse reports that the EOS cushion is very good after hip replacement surgery which can ordinarily be quite painful.  So yes, today I am ordering our 3rd cushion, all of which will be used every day.  I'm investigating gel matress covers for nighttime issues...
