The Serenity Hybrid Mattress combines premium pocket springs with memory foam to deliver tailored support and luxurious comfort, ideal for all sleep positions. With hundreds of high-quality stainless steel pocket springs working independently, this mattress provides targeted support to seven key body areas—feet, legs, hips, waist, shoulders, neck, and head—aligning your spine and enhancing your posture for restful, pain-free sleep. The ergonomic hybrid design blends the pressure relief of memory foam with the resilience of coil springs, creating a cushioned buffer that relieves muscle tension and improves sleep quality.Breathable and moisture-wicking, the hybrid foam and pocket spring layers ensure excellent airflow, keeping your body dry and comfortable all night. The plush, soft surface feels like floating on a cloud, while the medium-firm base gives the perfect balance of comfort and back support, reducing motion transfer so you and your partner can enjoy undisturbed sleep. Conveniently compressed and boxed for easy shipping, the Serenity Hybrid expands to its full shape at home and is compatible with all bed frames—whether box springs, slatted bases, or flat platforms. Choose the Serenity Hybrid for unmatched value, comfort, and targeted support. White Noise Size: Double (4'6)
