You might try foam "filter" media from either a HVAC (or maybe a 
swimming pool store) as it might be soft enough and comes in rolls. OR 
perhaps a trip to your local Walmart is in order for an "Egg Crate 
mattress topper" or maybe look in the sewing section.

My dilemma is that the unit has developed an issue with contact that is either due to an issue with the hinges or a breakdown of the foam. I am trying to find a large piece of sheet foam approximately 50x36x0.125” or bigger and it need to be very easily squished. Does anyone have a suggestion to a specific item or a type of material that might work for this?
