Latex mattress come in various types, including all-zone, three-zone, five-zone, and seven-zone designs. The concept of zoning refers to the customization of the mattress based on the body's gravitational pressure during sleep, with varying degrees of firmness in different zones to better support and protect the body, ultimately achieving a good night's sleep. More zones are not necessarily better; it depends on your sleeping habits. Theoretically, a three-zone mattress is ideal for back sleepers, while a five-zone mattress is more suitable for side sleepers, as the body's curves are more pronounced when sleeping on one's side, requiring additional support. However, in terms of actual feel, the difference between the two is not significant.
