Zinus 3-Inch Green Tea Memory Foam Mattress Topper Full — Odor-Reducing, Pressure-Relief Comfort Layer

The Zinus 3 Inch Green Tea Memory Foam Mattress Topper is a removable comfort layer infused with green tea and charcoal to neutralize odors while contouring to your body for pressure relief.

Replace a thin, worn mattress surface or add a softer, fresher feel to your bed without buying a new mattress. This 3-inch topper combines slow-recovery memory foam with green tea and charcoal infusion to help manage moisture and odors, while the foam conforms to your natural curves to reduce pressure points. It ships compressed in Zinus’s compact WonderBox for easier handling and lower shipping impact.

How does this topper freshen my sleep environment?

The infusion of green tea and charcoal is built into the foam to help neutralize odors and absorb excess moisture over time. This is a passive, ongoing effect during normal use and contributes to a fresher-smelling sleep surface. The materials are incorporated into the foam, not sprayed on, so the function lasts as long as the foam remains intact.

• Green tea infusion helps minimize common mattress odors.
• Charcoal aids moisture absorption to reduce damp smells.
• Infused throughout the foam for long-lasting freshness.
• Works without added sprays or topical treatments.

Will it ease back or pressure-point discomfort?

This memory foam layer is designed to cradle your body's curves and distribute weight more evenly, which can reduce localized pressure on shoulders, hips, and the lower back. It provides slow, responsive support that adjusts as you move, helping you find a more comfortable sleeping position. While it often relieves discomfort caused by a firmer or uneven mattress, it isn’t a medical treatment.

• 3-inch memory foam contours to natural body shape.
• Reduces concentrated pressure at common contact points.
• Adaptive, slow-recovery response to movement.
• Compatible with most mattress types and firmness levels.

How easy is setup and will it fit my mattress?

The topper arrives compressed and rolled inside Zinus’s WonderBox for simpler transport and lower packaging volume. Unbox, unroll, and allow the foam several hours to expand back to full size—most expansion occurs within 24 to 72 hours. It’s built to fit standard mattress sizes and works under most standard and deep-pocket fitted sheets.

• Compressed WonderBox packaging for convenient delivery.
• Simple unroll-and-expand setup; expansion in 24–72 hours.
• Universal fit for standard and deep mattresses.
• Lightweight enough for one-person placement on a bed.

Is the foam safe and durable?

The foam is CertiPUR-US certified, meaning it meets standards for low emissions and material safety and is manufactured without certain harmful chemicals. Zinus backs the topper with a three-year warranty covering manufacturing defects, providing additional peace of mind. Regular use and proper care help preserve the foam’s performance over time.

• CertiPUR-US certified for low VOCs and safety.
• 3-year limited warranty against defects.
• Durable memory foam designed for consistent support.
• Care straightforward: rotate and use a washable cover as needed.
