Signature Firm

Our Southerland Signature Firm provides a solid, supportive surface that lets you sleep "on" it rather than "in" it. With minimal sinkage and less body contouring it offers strong spinal alignment for stomach and back sleepers.

Its Premium Knit Cover, crafted from high-quality, elegantly designed fabric, offers a refined look and a smooth, breathable surface. Quilted into the top layer, 1 ½” HD Quilt Foam adds slight cushioning for an inviting sleep surface.

Beneath the quilt, 1 ” HD Comfort Foam, engineered with Southerland’s Comfort-lock® process, ensures lasting comfort and support. At the core, the 8″ 800 Series with PowerEdge® system provides responsive, targeted support while minimizing motion transfer and delivering enhanced edge stability. A final layer of ¾” HD Base Support Foam absorbs movement and reinforces the mattress for years of consistent performance.

Mattress Foundations are Sold Separately!
