Description

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.

Construction

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.
