Mango says the mattress is made without chemical fire retardants. Ask the seller for the full material list if you have sensitivities.

Mango describes it as a natural, chemical-free sleep system handmade in California. Detailed layer and foam specs are not published, so ask the seller for density figures.

Our take on the Mango Firm King Natural Mattress

The Mango Firm King is a handmade-in-California natural mattress built without chemical fire retardants. It is a firm all-foam design aimed at sleepers who want a dense, supportive surface and fewer synthetic materials. Against mainstream memory-foam kings it trades plush contouring for firmness and a cleaner material story. It includes a 100-day comfort trial and a 25-year warranty, terms that are longer than most rivals offer.
