Engineered for those who prefer firmer support without sacrificing comfort, the Harper range is a standout solution in sleep technology. This collection combines thoughtful design and durable components to deliver a mattress that holds its shape, supports your posture, and enhances rest for years to come.
At the core of every Harper mattress is the trusted CoreSupport spring system. This Sealy-exclusive technology features a single-stage, twice-tempered coil system with six active turns, designed to deliver consistent deep-down support while contouring gently to the body's pressure points. It’s a perfect match for sleepers who value firmness, structure, and full-body alignment.
Harper also includes the innovative EdgeGuard support system, extending the mattress’s usable surface and reinforcing its perimeter. This means a more stable seating edge and confident edge-to-edge sleep support—especially important for those who move around during the night or share their bed.
HealthShield antimicrobial treatment is integrated into the comfort layers to create a cleaner, healthier sleep environment, while rigorous product testing ensures long-term performance and resilience.
Perfectly paired with any Sealy base—including standard, adjustable, or storage designs—Harper brings together practicality, hygiene, and superior value. It’s an ideal choice for anyone seeking a firm feel backed by intelligent construction and trusted Australian craftsmanship.
