is a collection of four models: Cloud
. These are innerspring
mattresses with foam
comfort layers. All four models have latex in the comfort layers. Waterfall

claims its Tranquility
models have "natural" materials. It's Eco-Flex
foams use plant-based ingredients.
Mattresses in the Tranquility Collection
are rated as "highly conformable." This conformability begins with the innerspring. It is made of individually wrapped pocket coils (a.k.a. Marshall coils). Their independent responses conform to body contours to lessen pressure and promote proper spinal alignment. Pocket coils also eliminate motion transfer, so when one sleeper movers, the other one is not disturbed.
The three principal materials found in the comfort layers of Tranquility
mattresses are latex, memory foam, and gel. The latex is natural Talaly latex, made from the sap of the Brasilian rubber tree. Latex is reslilient, quickly recovering its original shape when weight is removed.
The memory foam contains soy-oil. Memory foam is conformable. For a brief time, it remembers the shape of the weight pressed on it.
Gel is supportive and cooling. It is infused into mattress foam for those reasons.
