Mattress
San Antonio's Solid Waste page accepts mattresses in curbside bulky collection, which it says is provided twice per year, and says to wait for a door hanger before setting the pile out. The code-enforcement page calls the brush and bulky collections two free collections per resident. A mattress can also be dropped at a bulky waste collection center. That page says the visit is free if you pay the environmental fee, and it refuses mattresses with blood stains or bed bugs.
