How firm is the Zinus Calm 10"?

Zinus rates it medium to plush. Most owners describe a soft, contouring feel rather than a firm one, so heavier sleepers may want something firmer.

Does the cooling gel layer really keep it cool?

The gel-infused top layer is designed to draw heat away, and many owners say it sleeps cooler than standard memory foam. It is still an all-foam mattress, so hot sleepers should pair it with a breathable cover.

How long until it fully expands?

It ships compressed in a box and usually reaches most of its height within a day. Zinus allows up to 72 hours for full expansion.

Does it work on an adjustable base or slatted frame?

Yes. A 10-inch all-foam mattress bends on adjustable bases and works on slatted frames with closely spaced slats or a solid platform.

What is the warranty?

Zinus backs the mattress with a 10-year limited warranty.

Is it good for couples?

Yes. The all-foam build absorbs motion well, so one sleeper moving is less likely to disturb the other. Edge support is limited, though.

Our take on the Zinus Calm 10" Full Tight Top Cooling Gel Memory Foam Mattress

The Zinus Calm 10" is a bed-in-a-box memory foam mattress with a tight top and a medium-to-plush feel. Its top layer is gel-infused memory foam for temperature control, over green tea and charcoal-infused comfort foams that Zinus says keep the mattress fresher longer. It suits side sleepers and couples who want pressure relief without a luxury price, and it competes with other budget foam boxes on layers and warranty rather than on coils or edge support. Owners rate it well overall but some find it softer than expected and slow to fully expand.
