# Why are Latex Mattresses So Famous?

Benefits of Latex Mattresses
Aside from being Eco-friendly and extremely comfortable, latex mattresses are naturally cool, and don’t have the heating problems that some other mattresses can develop.

Latex mattresses are also durable, especially if they’re made of natural latex. You don’t even have to flip the mattress; it stays comfortable where you first put it. Most latex mattresses can last more than 20 years.

Where Does Natural Latex Come From?
Natural latex is harvested from rubber trees, and because it’s natural, there’s minimal off-gassing. 100% of natural latex mattresses are harvested from the tree, so there are no harsh chemicals in the mattress.

How Is Synthetic Latex Different from Natural Latex?
Not all latex mattresses are 100% natural. Synthetic latex can be made of various materials, but are typically made with a certain type of plastic called SBR, or Polystyrene Bernadine Rubber, which is commonly used as a substitute for natural rubber. This plastic is often used for artificial turfs for children, and research has shown the chemical to be safe, though there is some controversy surrounding it.

A synthetic mattress is probably not going to have the durability of an all-natural latex mattress, and doesn’t have the same springiness to it that many look for in a natural latex mattress.

Latex is Well-Known for Being Comfortable
Latex foam mattresses are highly comfortable, which is a big reason they’re so popular. They’re springy and bounce back once pressure lifts off of them, but they also contour to the body.

Latex mattresses are ideal for sleepers who move a lot at night. Unlike memory foam, latex mattresses don’t take long to reshape to the body after it moves.

How Do They Make Latex Mattresses?
Dunlop Method – Complete Fill of Mold
The Dunlop manufacturing method fills the mattress mold completely, which usually results in a lighter top and a denser bottom to the latex foam still the tree sap settles a bit toward the bottom.
