The Southerland Cobalt Medium Mattress is a medium innerspring mattress built for combination sleepers and most body types. Southerland's Scandinavian collection layers gel-infused memory foam over an offset-coil unit for cool, supportive sleep at a working family budget. At 13.5", 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.
Each coil moves on its own, so a partner getting up doesn't roll you out of position.
We deliver, set up in your bedroom, and haul away your old mattress — no extra charge.
A 5/10 firmness — soft enough to relieve pressure on shoulders and hips, firm enough to keep your spine in line. Most-recommended firmness for combination sleepers.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
With roots tracing to 1893, Southerland’s unending commitment to its customers and business partners has allowed us to grow into one of the largest and most respected bedding manufacturers in the United States. Because America sleeps on Southerland, we think it’s important that our sleep systems are made in America.
