Super floppy. It’s a very open cell foam. I wouldn’t expect it to handle any sort of heavy /sharp weight without being possibly permanently dented. It’s pretty standard polyurethane foam.
It feels exactly like the headliner of a fabric-lined car. It’s actually really weird to feel that texture out of context.
I just test fit it to a pen slot in a box, it’s perfect for that. Very pleased.
Like a lot of foams and plastics, it sort of fuses after the beam passes. This actually worked out nicely, because it meant I was left with a perforated “punch out” situation, where the pieces didn’t come out of the larger material until I pulled it apart after the fact. It was easy to do and kept everything in position, the air assist didn’t make it move around.
There are cheaper sources of this stuff, but the was the only one that I found that was confirmed polyurethane foam and cotton fabric. Both seemed really laserable.
