The Southerland Cobalt Firm Mattress is a firm innerspring mattress built for back and stomach sleepers, and plus-size sleepers. Southerland's Scandinavian collection layers gel-infused memory foam over an offset-coil unit for cool, supportive sleep at a working family budget. At 13", it sits in the standard profile range — generous enough for adjustable bases yet still easy to sheet.
A foam-encased perimeter lets you use the full sleep surface — and sit on the edge to dress.
A reinforced center third keeps the spine aligned across every position.
We deliver, set up in your bedroom, and haul away your old mattress — no extra charge.
