Overview
No coils or springs here: the Zinus Green Tea mattress layers memory foam over a durable base foam inside a breathable knitted cover. It ships rolled, then expands on a platform bed, box spring or adjustable base.
Zoned pressure relief lets hips and shoulders sink while the rest of the body stays supported, which helps side, back and stomach sleepers alike. The cover is spot clean only, so a protector is a sensible add, and no warranty is listed.
Who it's for
Couples or solo sleepers with a California King frame get a foam bed that absorbs movement and suits any position. Those who prefer a springy, bouncy surface or a machine washable cover should look elsewhere.
Pros and cons
- Absorbs movement between sleeping partners
- CertiPUR-US certified foams
- OEKO-TEX certified cover, no fiberglass
- Green tea and charcoal fight odors
- Cover is spot clean only
- Warranty not listed
- Mild off-gassing smell at unboxing
- Needs days to fully expand
Performance notes
Memory foam contours under pressure, so it shapes around hips and shoulders and spreads load across the surface. The zoned system makes some areas yield more than others, while the dense base foam limits how far the comfort layers compress. Foam absorbs motion rather than passing it along, so a partner turning over is felt less.

Frequently asked questions
What comes in the box with the Zinus Green Tea mattress?
Only the mattress, rolled for shipping. No foundation, frame or bedding is listed, so it needs a platform bed, box spring or adjustable base you already own.
How long before I can sleep on the Zinus Green Tea mattress?
Let it expand for 24 to 72 hours after unrolling. A mild smell at unboxing is normal off-gassing and typically fades within 24 to 48 hours.
Does the Zinus Green Tea mattress have springs?
No. It is an all-foam mattress with memory foam comfort layers over high density base foam, so there are no coils.
Can I wash the Zinus mattress cover?
The care instructions say spot clean only, so treat stains by hand rather than putting the cover in a washer.
