Great cushion, retains it's shape nicely
Have been using since June 2014 and I really love it.  For extended sitting and relieving discomfort, this seat cushion helps.  I don't know what I'd do without it.  Mine has not lost any of it's shape at all.  Everything is exactly as it was when I first got it.  I'm about 125, 5' 3&#34;.  I'll update if any change, but don't see that happening.  I would highly recommend.
