Does align pelvis
The Sacro Wedgy does align my pelvis.  It is hard feeling on my body, however.  Granted, I don't have much "padding".  I have placed some material over it to soften it, and can last about 8 minutes before it gets too uncomfortable.  Although I am certain it must position the pelvis more optimally, I can get a similar action by laying on a softly inflated "Mirable Ball".  As I work with it more, I will most likely find something better to lay over it to make it more comfortable.
