Be Warned- not for under your knees
I have been looking for a month for the right support under my knees to for sleeping with a bad back.  Chose this due to reviews.  Maybe better as a pillow as the packaging shows.  First it barely  measure 3&#34; high on the end - promoted as 5&#34; high.  It comes rolled up so the foam is a smashed down and has creases.  Looks nothing like pictured by seller with knees bent up.  The pillow is quite flat.  NOT usable as support for under your knees, so sending back.  Before the seller comments, yes I unrolled and tried to let it puff up.  But no support for legs.
