Abstract: A mattress comprising asymmetrical coil springs with spring rates that provide 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 compress with a first substantially constant spring rate for a substantial part of compression, and with a second substantially constant spring rate for a remaining part of compression. The result is a mattress that is sufficiently soft for lighter users and sufficiently firm for heavier users.
