but I was bored enough to put keys
I just receive this one, day one I feel really wired, it's firm but not that typical &#34;firm firm&#34;. I didn't  do the egg test, but I was bored enough to put keys, nail polish, hand lotion tube ... to test, you barely feel them, meaning the cushion absorb the pressure. Magic happened on day three, my but pain is gone, ok ,I will keep it.
