Why can I feel the coils in certain spots?

That is the zoned coil layout working as designed. The center third uses firmer, reinforced coils to support the lumbar region, so the support can feel slightly stronger across the middle than at the head and foot. With only 1 inch of comfort foam over the springs, that firm structure sits closer to the surface. A mattress protector or thin pad softens the sensation without changing the support.
