Slumber Firm

Experience consistent, supportive comfort with the Slumber Firm. Designed for sleepers who prefer a sturdier feel, this model combines targeted lumbar reinforcement with durable materials for long-lasting performance and dependable alignment.

A 1” quilted luxury fabric cover creates a smooth, breathable surface with a refined finish. The tailored quilting enhances initial comfort while maintaining the firm feel underneath.

Beneath the surface, 1.8” of Green Soy Bio high-density foam adds resilient cushioning and long-term durability. This eco-conscious comfort layer delivers steady support without excessive sink, helping maintain proper posture throughout the night.

An additional 0.5” DS Signature Double® lumbar support layer provides targeted reinforcement in the center third of the mattress. This focused support promotes spinal alignment and reduces strain on the lower back — especially important for back and stomach sleepers.

At the core, a 9” 360° ultra high-density foam-encased zoned pocket coil system delivers responsive, individualized support. Each coil adapts independently to your body’s weight and movement, reducing motion transfer while reinforcing critical pressure points. The foam-encased perimeter strengthens the edges, expands usable sleep space, and enhances long-term durability.

The Slumber Firm offers structured comfort, enhanced lumbar stability, and reinforced edge support — making it an excellent choice for sleepers who want a firm, no-nonsense feel with modern pocketed coil performance.
