Excuse me, what is the material of the mattress that is good and environmentally friendly? I want to buy one for my parents.

The 3D mattress does not contain formaldehyde, which can protect the spine, because the 3D mattress has the best supporting effect and can fit the curve support of the human body. Moreover, the 3D mattress can be washed (not afraid of children wetting the bed) and has the advantages of anti-mite, anti-mildew and mute. My family all like Benyou.3D mattress.
