Serta Cobalt Calm Plush Tight Top – Soft Feel, Clean Profile
$10.99
Plush without the pillowtop is a real category. The Cobalt Calm Plush Tight Top folds its softness inside the build – Cool Twist Gel Memory Foam contour, PillowSoft Aire cushioning – and keeps the sleep surface flat, with none of the sewn-on lift a pillowtop adds to the bed’s profile.
Underneath, the same 850-coil three-zone system as the rest of the Cobalt Calm family reinforces the lumbar and hips. Side sleepers who like low-profile bedding and neatly tucked sheets tend to be exactly the audience.
Cape May shoppers can compare it against the Plush Pillowtop in one stop at The Mattress Store inside our Northfield showroom – same engineering, different silhouette.
Questions & Answers
How can a tight top be plush?
The soft comfort layers sit inside the build instead of being sewn on top – you get plush give at the surface with a flat, tailored profile on the frame.
How does it differ from the Cobalt Calm Plush Pillowtop?
Same coil system and similar softness; the Pillowtop adds a sewn-on cushion layer and extra height. This tight top keeps the profile lower and the surface flat.
What sizes and prices does it come in?
Twin $899, Twin XL $949, Full $979, Queen $999, King $1,399.
What support is underneath?
Serta’s 850-coil Custom Support system with three zones – reinforced through the lumbar and hip region, standard support elsewhere.
Who is this mattress best for?
Side sleepers who want plush comfort with a cleaner, lower mattress profile – and anyone who prefers sheets that tuck neatly.
