About the White Dove Duality 400 Firm Mattress

Firm Support. Dual-Sided Durability.

The Duality 400 Firm Mattress by White Dove offers the perfect combination of long-lasting support and premium craftsmanship. Designed with a dual-sided sleep surface, this mattress features dense, supportive foams and a tri-zoned pocketed coil system that delivers extra lumbar reinforcement—ideal for those who prefer a firmer, more stable feel. The flippable design allows you to rotate the mattress regularly, extending its life and preserving that just-right level of support night after night.

Every White Dove mattress is handcrafted in the USA and goes through a meticulous 15-point inspection process—part of a tradition of excellence from a fourth-generation, family-owned company.

Premium Features for Elevated Sleep

• Handcrafted Durability: 16 hand-placed tufts keep each comfort layer securely in place, preventing shifting or sagging—even on adjustable bases.

• Targeted Comfort Layer: Firm-feel specialized foams sit just beneath the surface to provide cushion without compromising support.

• High-Density Core Support: 1.5 lb. high-density foams add to the mattress’s durability and reinforce its firm comfort profile.

• Tri-Zoned Coil System: With 1,000 individually wrapped coils, including a reinforced center third, this system offers precise support where your body needs it most.

• Edge-to-Edge Sleep Surface: Reinforced edges provide a stable, fully usable sleeping area—no slipping, no sagging.

• Two-Sided for Extended Life: Mirror-layered construction allows you to flip the mattress for a refreshed surface and twice the lifespan.
