Zinus 3" Green Tea Cooling Gel Memory Foam Mattress Topper, Queen — 3-inch Cooling, Odor-Reducing Comfort

The Zinus 3" Green Tea Cooling Gel Memory Foam Mattress Topper adds a cooling, contouring comfort layer to your mattress while arriving compressed in easy-to-handle WonderBox packaging.

This topper combines cooling gel-infused memory foam with green tea extract and activated charcoal to help reduce odors and regulate sleeping temperature. Designed to expand to full thickness after unpacking, the topper is CertiPUR-US certified for content and durability and comes with a 5-year limited warranty. It’s a budget-friendly way to refresh an older mattress or add plush support to a firmer bed without buying a new mattress.

How quickly will the topper be ready to sleep on after unboxing?

Unbox and unroll the topper, then allow it to expand. While it regains most of its shape within a few hours, full expansion and optimal performance can take up to 72 hours.

• Ships compressed in Zinus WonderBox for easier handling and lower shipping footprint
• Initial foam scent is normal and typically dissipates within 72 hours
• Gently air for faster off-gassing if desired

Will this topper help me sleep cooler through the night?

The memory foam contains thermoregulating gel designed to draw heat away from your body and a breathable foam structure to improve airflow. Together they reduce trapped warmth compared with traditional memory foam toppers.

• Cooling gel infusion helps moderate surface temperature
• 3-inch profile balances contouring and airflow for many sleepers
• Green tea extract and activated charcoal help maintain freshness over time

How does the topper change mattress feel and support?

The topper’s conforming memory foam cradles curves to relieve pressure points while adding a softer, more enveloping surface. It’s ideal for reducing the perception of firmness on a hard mattress without sacrificing support.

• 3-inch thickness provides noticeable cushioning without excessive sink
• Memory foam contouring redistributes pressure for improved comfort
• Compatible with most mattress types and bed frames

What should I expect about care, durability, and safety?

The topper uses CertiPUR-US certified foam, assuring independent testing for emissions and durability. Spot clean the cover as needed, avoid machine washing the foam, and follow Zinus care guidance to extend lifespan.

• CertiPUR-US certification for foam quality and emissions
• 5-year limited warranty for manufacturing defects
• Spot clean only; avoid saturating or machine washing the foam layer
