Got to LOVE Amazon's customer service
This cushion was shipped extremely fast but I had to return it.  I found it to be very uncomfortable to sit on!  Also wants to slide forward.  I received  a credit within 2 days after sending it back. Got to LOVE Amazon's customer service!!!  I have the original  Wondergel cushion that I purchased from Amazon for $46.00 and like it better.  It is thinner and more comfortable for me.
