Our take on the Zinus Spa Sensations Serenity 12" Queen Mattress

The Spa Sensations Serenity is a 12-inch all-foam queen mattress from Zinus: a Serenity memory foam top layer over ventilated comfort foam, with a velour cover. The memory foam is infused with green tea and active charcoal to limit odors, and the ventilated layer is meant to keep the surface cooler. It suits side and back sleepers who want a deep, pressure-relieving foam feel without springs, and it ships rolled in a box with a 10-year warranty. Against spring and hybrid rivals it is simpler and softer, but it lacks edge support and sleeps warmer than coils.

Questions and answers

How firm is the Serenity 12-inch?

It is a medium-soft all-foam mattress. The memory foam top layer sinks in around shoulders and hips, so it suits side and back sleepers more than stomach sleepers.

Does it sleep hot?

The ventilated comfort foam is designed for airflow, but owners often report it sleeps warmer than a hybrid or innerspring. A breathable protector and cooler room help.

How long until it fully expands?

It ships rolled and compressed. Most of the expansion happens within a day, with full loft in about 48 to 72 hours.

Does it need a box spring?

No. It works on a platform bed, slatted frame or adjustable base. A solid, supportive foundation is best for foam.

What warranty comes with it?

Zinus includes a 10-year limited warranty covering manufacturing defects.

Is it good for couples?

Yes for motion isolation, since foam absorbs movement. Heavier couples may find the edges soft and the surface warm.
