The Cobalt Calm Plush Pillowtop is Serta's pillowtop innerspring — Cool Twist Gel Foam swirled into premium memory foam for cooling contour, PillowSoft Aire soft foam for the top cushion layer, and 3-zoned support coils for targeted lumbar and hip support.
This is Serta's answer to Beautyrest's pillowtop models at a lower price. Pillowtop over an 850-coil zoned support system means side sleepers get shoulder and hip cushion without losing back support. Anti-microbial technology keeps the mattress fresh from odor-causing bacteria over years of use.
At Queen it's a strong value pick for side sleepers wanting the pillowtop feel without stepping into Beautyrest Black pricing. Come compare it to the Anchor Island Plush Pillowtop at The Mattress Store inside our Northfield showroom.
Serta's memory foam infused with cooling gel — gel spreads heat away and adds contouring feel. The "twist" is the design pattern: swirled into the foam, not applied on top.
Coils are engineered in three zones of different densities across the mattress — supportive at the head and foot, targeted support under the low back and hips. Distributes weight evenly for spine alignment.
Serta's branding for their soft, breathable pillowtop foam — designed to feel cushiony without collapsing over time. Uses an internal channeling pattern for airflow.
No — the Cobalt Calm line has multiple variants: Plush Pillowtop, Medium Pillowtop, Plush Tight Top, and Extra Firm Tight Top. Come feel them side by side at Kensington.
Some pillowtop softening is normal — the top layers relax with use. Serta covers structural failure under the 10-year limited warranty, but expects some softening as normal wear.
