Does the mattress underneath the mattress affect breathability?
But, for a long time, cardboard can damp mildew, also the main body is unable to give a good support, it is not all parts of the body to relax at the same time, the number of turnover will increase, long past certainly will affect the quality of sleep.
This is why there are a variety of spring mattress, latex mattress, palm mattress, there are a variety of combinations, is to provide a flexible and sufficient support, people can have a comfortable sleep, so I do not recommend the mattress pad to cardboard.
