Abstract
A mattress comprising asymmetrical coil springs with nonlinear spring rates provides comfort to users with different weights. The lower portion of the spring is cylindrical and the upper portion is conical or frustoconical. This arrangement causes the spring to undergo linear compression before undergoing nonlinear compression. The result is a mattress that is sufficiently soft for lighter users and sufficiently firm for heavier users.
