**Q: Is this foam soft enough if building a facemask?   Do u have any softer?  1 inch thick is fine.   But do u have 1/2 inch thick?**
A: Yes

**Q: How is it delivered...is it compressed and folded or is it one long sheet?**
A: In a roll..in plastic wrap

**Q: I'm making a truck bed camper. Would this work for a pad to sleep on?**
A: I'm not sure if it would be the most comfortable. I used mine for storage with cutouts for some equipment and hardware. 
But it is possible and it cuts well with a box cutter or exactor knife so you can completely customize your sleep pad.
