   Foam rubber that will sink in water.

   From: NONONOmisc07@fmguy.com   
      
   K need something an inch, inch and a half, at most 2" thick which by its   
   nature won't float or which will fill with water and not float, which I   
   can sit on in the bathtub so that it not longer hurts to sit on thard   
   surface.   
      
   I'd also like to know if so-called AI is acting stupid again:   
      
   When I google   foam rubber that will sink   
   so called AI says   
      
    "Key Factors for Sinking Foam:   
      
       Closed-Cell Structure: This means air pockets are sealed, making it   
   less permeable to water and air than open-cell foam, but still   
   compressible."   
      
   Isn't this backwards?   If the cells are closed, they remain filled with   
   air, and the foam will float.   Right?   
      
   It also says "Dense Upholstery Foam: Look for ratings like "1.2 Density"   
   or "33 lb Compression" (ILD), as these provide support and are less   
   airy."   Do these 2 things sound correct?   
      
   If the foam becomes totally waterlogged, will the specific gravity still   
   make it float, beucas it's maybe 98% water and 2% foam rubber and the   
   foam rubber is lighter than water?  or will it stay at whatever depth   
   its place, stay on the bottom if it's placed there?   
      
   Since I lost weight, 270 to 200 on a 5'8" frame, I've lost a lot more   
   weight in my butt than I had originally gained there, so it's less   
   resilient than any time in my life before, and it hurts to sit in the   
   bathtub or on a hard chair, or even some padded chairs.   
      
   I miss taking a long pleasant bath.  I tried a piece of foam that they   
   sell to sit on in football stadiums and it floats. I can trap it but it   
   tends to escape, it's pretty inconvenient, and ii would be better if it   
   were thicker.   
      
   i found things for sale that are pre-weighted, but they are all 4.3 to 5   
   inches high and meant for hottubs so that women won't get their hair   
   wet.  My bathtub is already too shallow, so I don't want to lose  that   
   even if I were not fat at all, I can't get my whole chest underwater.   
   I don't want to lose 4+ inches even more depth.   
      
   I need something an inch, inch and a half, at most 2" which by its   
   nature won't float or which will fill with water and not float, but is   
   softer than steel.   
      
   Any ideas, products or materials, or suggestions?
