    So, I bought some of this...

    http://www.target.com/Comfy-Foam-Ma...mbrowse=0&index=target&rh=k:comfy foam&page=1

    to line my B15S cab with. I've read on here, mostly from BillFitzmaurice, that open cell is the way to go.

    However, the one I bought is not labeled as either. I put in an email to Target, where I bought it, and still no answer.

    So, how do you tell the difference?

    And, does it make a difference?

    I don't want to cut it up and ruin it in case I need to return.

    Thanks in advance!

    Open cell foam has as much air as foam and it's easily squished. You can actually see the pores in the foam, too. Closed cell foam is very rubbery and thick, like a pool float, and you can't see pores in it.

    Thanks for the links!

    Under the open cell is says furniture and bedding, and no such applications for closed cell...

    There is a weird flammable warning that freaked me out. This stuff catches fire and it sucks oxygen and is difficult to extinguish. This is ok still? Not that I plan on lighting fire to my cab!

    Exactly. Don't run the B-15 with the head still inside the cab and you'll be fine ;)

    Why wouldn't it be? My bed is pretty flammable too.

    You can blow your breath into and through open cell foam. On the other side you will feel heat, even though the air will have slowed down too much for you to feel air movement. When you do this, the ladies in the fabric department will look at you funny.

    Ok, this worked. Guess I have the right stuff.

    Thanks for all the help, guys, and the jokes!
