The CA King Southerland Scandinavian Collection Sandmahn III Plush Box Top Discontinued Floor Sample Mattress is a plush natural latex mattress built for side sleepers and combination 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 16", it sits in the premium profile range — generous enough for adjustable bases yet still easy to sheet.
Naturally cool and resilient — feels buoyant rather than sinking, and lasts longer than memory foam.
A breathable quilt and gel-infused top draws heat away so you don't wake up hot.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.
We deliver, set up in your bedroom, and haul away your old mattress — no extra charge.
