There are mattresses made of soy protein fiber, also known as soy foam or soy-based polyurethane foam. However, the majority of these mattresses still contain some petroleum-based materials and may also contain other chemicals.

As for the glue used in these mattresses, it depends on the specific brand and model. Some may use water-based adhesives that are free from formaldehyde, while others may use traditional adhesives that contain formaldehyde. It is important to check the manufacturer's specifications and look for certifications such as CertiPUR-US or GreenGuard to ensure that the mattress meets certain safety standards
