The Pure Health® Mattress has two air chambers that can be independently adjusted from "pillow-soft" to "extra firm" to suit the individual preference of each sleeper.
Constructed of vulcanized rubber, the chambers are extremely durable.
The configuration of the baffles forms a quilted pattern that keeps the
overall surface of the bed nice and flat, and is the best configuration
for sleeping comfort. (The Sleep Number® Mattress has air chamber
compartments that run across the mattress from left to right in a
"washboard" pattern.) Would you like to sleep on a
washboard?
