The Sonata Firm is perfect for Back-Sleepers looking for great back support. The Tencel cover is super wicking and helps you sleep cool. Southerland prides themselves on their construction methods, including pre-stressed foam to help your mattress feel new longer, highest density foams for longer lasting support, and quite possibly the lowest warranty issue numbers in the industry.
- Premium support coils are individually wrapped providing conforming comfort and reduced motion transfer.
- Our premium comfort foams include high-density memory foams and/or pure latex for superior support and comfort.
- The natural Tencel® in our premium cover is more absorbent than cotton, softer than silk and cooler than linen, improving moisture wicking and natural hygiene.
- High-density foams use our Comfort-lock® process and provide longer lasting support and comfort than our standard foams.
- Specifically designed to articulate on adjustable beds to customize your sleep experience.
