Coil types matter
Individually wrapped coils can move more independently than interconnected spring units, which can change contouring and motion behavior.
Responsive feel
Coil support cores generally produce a more buoyant, easy-to-move-on feel than deeply conforming all-foam designs.
Airflow
Open space through a coil core can permit more airflow than a solid foam core, although the complete mattress design determines sleeping temperature.
