Adjustable
Firmness
"Adjustable firmness" means that
the bed allows for its firmness to be made harder or softer.
Airbeds
Both the Sleep Number
/ Select Comfort and Comfortaire
beds provide adjustable firmness at the touch of a button.
They also offer separate air chambers which can allow each
side of the bed to have its own firmness setting independent
of the other.
Memory foam beds
These
mattresses do not offer adjustable firmness. However, one
can purchase a topper for the mattress that can change the
bed's firmness to harder or softer.
Waterbeds
Waterbeds can be adjusted in regard to firmness by adding
or removing water. This, of course, takes some work to do
and is not nearly as simple and easy as adjusting firmness
on an air bed.
Latex beds
These mattresses do not offer adjustable firmness in the same
convenient way that airbeds do. However, they can be custom
made to suit your firmness preference.
Innerspring / coil mattresses
Innerspring beds cannot be adjusted for firmness. However,
one can purchase a topper for the mattress that can change
the bed's firmness to harder or softer.
