摘要：
An innerspring assembly, such as for use in a mattress, comprises a plurality of coil springs defining upper and lower terminal convolutions and body portions therebetween. Adjacent coil springs are attached together at the body portions thereof with the terminal convolutions being unattached to one another, so that the terminal convolution can move independently of one another.
