EnglishBob, I downloaded your morphing mattress and used it to replace the one that's part of XCalPro's "classic" Trek recovery bed.  I also used it for the pillow.  The glittery fabric may obscure it, but I did "depress" the areas where the hapless security guard's body intersected with the mattress geometry.

What a clever solution you devised!  In case anyone reading this who has not yet grabbed this goody, 'Bob made 45 morph zones, 5 across its width and 9 along its length.  With this arrangement, one can "depress" the appropriate areas where you position your figure.  You are NOT limited to specific reclining poses.

A smart alternative when you don't want to struggle with "dynamic cloth" or "magnets".

Sincerely,

Bill

Tempt the Hand of Fate and it'll give you the "finger"!
