Mattress
Chicago's current sanitation pages say to arrange a bulk pick-up with the Streets and Sanitation ward superintendent before setting out any large item. Those pages do not name mattresses. The city's July 2021 waste-strategy reports do. One defines bulk as items that cannot go in regular collection because of their size, and gives mattresses as an example, and says bulk can be requested through 311. The other says large items such as mattresses are picked up during garbage collection, and that residents can also submit a 311 request for on-demand bulk pickup. The garbage-fee FAQ says there is no additional cost for bulk waste collection. City crews serve single-family homes and buildings of four units or less.
