High coil count and low steel gauge. "Coil count," the number of springs or steel coils a mattress contains, is a popular marketing point. But a generous coil count doesn't always mean a firmer mattress. The cheapest innerspring baby mattresses may have fewer than 80 coils and more expensive models may have more than 280 coils, but a model with 150 coils could be firmer than one with 200. How? The gauge of steel in those 150 coils may be thicker than the steel in the 200-coil mattress. Steel gauge for mattress coils ranges from 12.5 to 19; the lower the number, the thicker the steel. Thicker is stronger. So look for a moderate to high coil count--135 to 150 coils is a good midrange--and a lower coil steel gauge, 15.5 or below.
Baby Bargains recommends foam over coil mattresses, because foam is significantly lighter, and generally less expensive. They do state, however, that the firmness (is that a word? lol) of your mattress is what REALLY matters.
There is some good information in that part of the book, about choosing a mattress (starts on pg.100 of the 7th edition of the book), and it might be worth checking out. If you don't have the book, you could probably read that section in about 10 minutes or less at the bookstore.
