Towels over pocket coils ?

Hi LookingNow,

It would depend on what you were comparing it to. A support system that flexes under a mattress will generally feel softer than a support system that doesn’t flex at all (such as a slatted platform bed or foundation with rigid slats or a piece of plywood).

In general a support system that has little to no flex would be suitable under a one sided pocket coil mattress although a solid surface can reduce the airflow under the mattress which in combination with other risk factors can increase the chances of mold or mildew under the mattress (see post #10 here).
