No. Of every bad mattress idea on the internet, burning is the one with the strongest case against it, on three independent grounds, any one of which should settle it.
Ground one: it is illegal almost everywhere
Open burning of household waste is prohibited in most jurisdictions, and mattresses specifically fail even permissive rural burn rules, which typically allow only clean untreated wood and yard debris. Burn bans, air quality regulations, and fire codes stack on top. The penalties run from citations into serious fines, and if the fire spreads, into liability that dwarfs them.
Ground two: the smoke is genuinely toxic
A mattress is polyurethane foam, synthetic fabrics, adhesives, and flame retardant chemicals. Burning polyurethane releases hydrogen cyanide and other combustion products that firefighters treat as hazardous, this is not campfire smoke with a funny smell, it is chemically dangerous to you, your family, and everyone downwind.
Ground three: mattress fires do not stay polite
Foam burns hot, fast, and drippy, shedding flaming material that travels. Backyard mattress fires escaping into structures and brush is a recurring line in fire department reports, and flame retardants slow ignition, then the fire wins anyway.
Every alternative is easier than a felony
Municipal bulk pickup collects free in many cities. Recycling facilities recover most of it by weight. Donation rehomes the good ones. And a scheduled pickup from $85, price guaranteed, removes it from inside your home in a same or next day window, no matches involved.
If the mattress made you angry enough to consider fire, let a Loader carry it away instead. Cheaper than the citation, better for the lungs.
