What a great idea. I struggle sleeping on an inflatable matress when I go camping, so a proper matress for those weekend getaways would be nice. But I have to ask you, where do you get the black ABS (I assume ABS is that plastic piping that I get in my local DIY stores like Lowes, or Homedepot etc). The only color I've seen is the white, but I think by your photos that the black is definately in order.
