Actually, the best option for beds is to recycle them through Springback Recycling here in Fort Collins. They'll take foam cushions too. Most thrift stores will not accept mattresses, especially for resale, because of the possibility of bed bugs and other lurking pathogens. If they do accept them, they're likely going to the landfill.
No, you're best option for that stuff is the ARC thrift store. It'll still end up in the landfill, but you'll be rid of them.
