Purple is the way to go
I bought the $79 one for my work chair (awesome) and the less expensive one for home (again awesome). I have lower back issues and a hip issues and when I sit too long, just a half hour, when I get up I can barely walk. This cushion makes a big difference.<br />I have also ordered their mattress and pillow (not arrived yet) cause my tempurpedic of seven months is useless.<br />So far I am loving the purple, plus it's my favorite color. :)
