摘要： The systems and methods described herein include innerspring assemblies or innerspring cores for use with cushioning articles such as mattresses. The innerspring core may have one or more coil springs formed from a high-carbon steel wire alloyed with one or more suitable alloying elements such as titanium and copper and capable of imparting greater strength and durability to the innerspring core.

摘要： 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.
