How long does it take to fully expand?

Zinus says up to 72 hours, and warmth speeds it up. Cold rooms can stretch that to several days.

Is it good for side sleepers?

Yes, the 3-inch memory foam top cushions shoulders and hips. Petite to average-weight side sleepers get the most benefit.

Does it work for heavy sleepers?

It is rated up to 500 lbs in most sizes, but the soft foam compresses more under heavier bodies. Stomach and heavier back sleepers may want a firmer bed.

Does it need a box spring?

No. It works on a platform bed, slatted frame or adjustable base; a solid or closely slatted foundation is best.

What sizes are available?

Twin, Twin XL, Full, Queen, King and California King. The Twin supports up to 250 lbs; other sizes up to 500 lbs.

Spot clean only. The cover is not removable, so use a mattress protector for spills and stains.

What reviewers say

Owners generally call it a comfortable, supportive mattress for the money, especially for side sleepers and lighter adults. Common complaints are the initial chemical smell, softness that some find excessive, and weak edges.

What people mention

ComfortPraisedSleepers describe a soft, conforming surface that eases pressure on hips and shoulders.
OdorCriticisedMany report a chemical smell that fades over the first few days after unboxing.
FirmnessMixedLighter and side sleepers find it supportive, while heavier sleepers say it sinks too much.
Edge supportCriticisedThe perimeter compresses easily, so sitting or sleeping near the edge feels unstable.

DurabilityMixedSome owners report body impressions and softening after a year or two, others see little change.

About the Zinus 12 Inch Green Tea Memory Foam Mattress

This is a 12-inch memory foam mattress with three layers. The top layer is 3 inches of conforming memory foam infused with green tea and ActivCharcoal. Below it is 2 inches of soft comfort foam with open air pockets that encourage airflow. The base is 7 inches of high-density support foam. The foam is CertiPUR-US certified.

The green tea is meant to keep the mattress fresh, and the ActivCharcoal microparticles block moisture. The foam layers relieve pressure at the shoulders, hips and knees. The mattress is medium firm with a smooth knitted jacquard top. It suits side sleepers and petite to average weight sleepers.

The mattress arrives compressed in one box. Take it out, unroll it and let it expand. It reaches full shape within 24 to 72 hours, and faster in a warm room. Walking or sleeping on it speeds up expansion. A 10-year limited warranty is included.
