go to a foam store and they usually gut foam and ask to keep the scraps
Where is this "foam store" or do you mean like a sleep country or the brick or something.
i dunno look themn up on yellow pages or google its probably a soft furnature store with supplies to reapolster chairs and shit i know there is one like that somewhere in edmonton
or go behind a brick store because they usually throw out matresses
I'm also building one and am looking for better ideas. my best is to get old matresses (spring ones) and ahve a layer of them on the bottom for some spring. Then the have random soft objects like teddy bears and old pillows. after a layer of that just the usual couch/matress idea. If anyone has a better idea be sure to post for us
if you have a college that has a foam pit there required to throw there foam away once a year and replace talk to someone in the college and ask when they throw it away then go and pick it up
