The Helena Firm is a 14-inch hybrid mattress from Spring Air's Grand Hybrid line, pairing cooling foams with zoned pocketed coils. Its center third uses coils 25% thicker to firm up lumbar support, and four cooling layers plus a phase-change cover target hot sleepers who want a firm, low-sink feel. It suits back and stomach sleepers and heavier sleepers who want edge support and alignment. Against softer hybrids, it trades plushness for stability; against all-foam firm beds, the coil core adds airflow and bounce. Owners rate it highly, though some find it firmer than expected.

The Helena Firm is a 14-inch hybrid mattress from Spring Air. It has a firm feel with less sink. It pairs cooling foams with zoned, individually pocketed coils to give a stable surface that supports spinal alignment and cushions pressure points.
The cover uses phase-change material to help regulate surface temperature. Beneath it are cool gel memory foam, a high-performance cooling foam and breathable Serene foam. Together they make up 4 cooling layers that reduce heat build-up and improve airflow.
The coils are twice-tempered and individually pocketed, so they respond independently to reduce motion transfer. The center third of the mattress has coils that are 25% thicker to support the lumbar area. A foam encasement and high-density foam add edge-to-edge stability and lasting perimeter support.
