Which is better for side sleepers?

The Serta Cobalt Calm Plush, because its plush pillowtop and contouring gel foam cushion the shoulders and hips more than the Sealy's soft tight top.

Which is better for back pain?

The Serta, because its three-zoned coils add support under the middle of the body. The Sealy's single-zone Stability Coils give even support but no zoning.

Is the Sealy worth the extra over the Serta?

The Sealy is not the extra-cost option here: it is $492.30 at Macy's as of November 3, 2026, and includes a box spring. The Serta's price is not given in the data provided, so compare it at checkout.

The Sealy's tight top generally holds its shape longer than a pillowtop, which can compress over time. The Serta's plush pillowtop is more prone to softening, so rotate it regularly.

Do both work with an adjustable bed?

Yes. Both list adjustable bed compatibility, so either can go on a power base.

Which comes with a box spring?

Only the Sealy set. It ships with a standard 9-inch or low-profile 5-inch box spring. The Serta is the mattress only.
