How many coils make a good mattress?

The number of coils in a mattress isn't really something that needs to considered all too greatly. There are many aspects that make a good mattress, including the coil configuration, and the poundage of steel at the mattress core.

For a peaceful night's sleep, the mattress should also be able to provide weight-balanced support for all over the body, and be able to adjust to the contours of the body. The number of coils is not an indicator of good quality mattresses.
