[QUAD-L] Circulation Improving Seat Cushion-Hammacher Schlemmer

[wheelchair]

Greetings,
While talking with an old friend recently, I was advised that his wife had  
purchased a cushion for him as a gift from Hammacher Schlemmer, called the  
Circulation Improving Seat Cushion.  It is not a medical device nor is it  
approved by any government insurance but...... or butt, I wonder if the 
product  has any merits.
My friend is a C4 Complete Quad for 5 years and loves it.  At 300  bucks it 
should do something.....
Anyone else heard of this device?
 
Best Wishes
