Mattress manufacturers are not required to disclose what type of flame retardants they apply or that come presoaked into the fabrics and fillings they source that get added into the finished mattress. These materials are considered proprietary, basically "trade secrets" that can also be kept secret from the end user. This applies to mattresses "marketed as organic" as well. Quotes are used as there are no organic regulations that pertain to mattresses.

The video below shows what we mean by smoothed to new. If your fillings are able to be fluffed or smoothed even, your mattress can never wear out unevely in the main sleeping zones. Springs can wear out unevenly as well. Many folks suffer from back pain but don't want to admit the cause is the mattress that they just purchased a few years ago.

If you cannot access or change out your mattress fillings then you are buying a disposable mattress that is doomed for the landfill within 5 years. Manufacturers do not test their mattresses for 25 years before selling them, that 25 year warranty claim is just marketing and the seller is simply playing the odds you won't actually ship your mattress back to them for the refund.

Imagine disposing of your current mattress by mulching your organic garden with it. Yeah, please don't do that unless you made your own mattress using the best organic fillings you could source.
