This is an awesome seat cushion!
This is an awesome seat cushion!  I mostly wanted it to help give me a little extra height while driving my car.  I am only 4'9&#34; and always have to sit on a cushion.  I have never found anything that REALLY works for more than a couple weeks.  This is super comfy and raises me up for sure... I actually had to lower my drivers seat while sitting on this.  I love it!  I have not tried the egg test, I'm too chicken!  ;-)<br />Highly recommend!  The only negative is that it's SO expensive.
