Many people are having foam mattresses in their home, since they are softer
However, the foam mattresses are likely to heat up more at night, since they absorb and retain the heat.
In comparison coir and latex mattresses do not retain heat, so the person sleeping is less likely to sweat
Due to the heat retention , the person may be forced to switch on the air conditioner for cooling, so that he or she can sleep well.
This will increase the electricity bill further.
