Born from Spring Air’s Dura-Last performance line, this mattress is built for resilience — crafted with high-density comfort foams, a responsive latex layer, and a robust 1000-tri-zone coil system for advanced support.

Hand-tufted for stability and long-lasting shape, it ensures you won't sag or lose loft over time.

Key Features

HD Soft & Firm Quilt Foam: Dual-layer quilt foam creates a firm, yet slightly cushioning surface—offering subtle comfort without compromising support.
Latex Comfort Layer: A resilient latex adding responsive support, pressure relief, and natural breathability.
Firm Comfort Foam: Deep-set, high-density foam that sustains firmness throughout the body of the mattress to resist sagging.
8" 1000 Tri-Zone Coil Unit: Strategically zoned innerspring design provides firmer lumbar support while offering gentle transition zones at the shoulders and legs.
High-Density Foam Encasement: Foam borders around the coil unit reinforce edge support—makes the entire sleep surface usable and stable.
Firm Base Foam: Dense foundational foam supports the coil structure and ensures long-term durability.
Hand-Tufted Construction: Secure stitching throughout prevents shifting of internal layers, maintaining mattress integrity over years of use.

Q: Will this mattress soften over time?
A: Very little. High-density comfort layers and hand-tufted construction help maintain firmness and shape over years of use, resisting sagging.

A: Yes. The high-density foam encasement reinforces the perimeter, allowing you to utilize the full sleep surface without roll-off.

Q: Does it sleep hot or cool?
A: While there’s no active cooling gel, the latex layer and innerspring design facilitate decent airflow—cooler than an all-foam mattress, yet pleasantly firm and supportive.
