Zinus 2" Swirl Gel Cooling Memory Foam Topper Twin — 2-inch Cooling, Airflow Design, CertiPUR-US

The Zinus 2 Inch Swirl Gel Cooling Memory Foam Mattress Topper is a thin, gel-infused memory foam layer that adds cooling comfort and airflow to your twin mattress while shipping compactly in Zinus's WonderBox packaging.

If you sleep hot or need a quick comfort upgrade without buying a new mattress, this 2" gel memory foam topper gives you a cooler, softer surface that still fits under standard and deep-pocket sheets. The foam is CertiPUR-US certified for durable, low-emission materials and arrives compressed in a smaller, eco-minded box for easier handling and reduced shipping waste. Expect the topper to expand to its full shape within about 72 hours after unboxing; a short new-foam scent is normal and fades quickly.

How does the gel swirl help reduce nighttime heat?

The topper's memory foam is infused with a cooling gel and sculpted with wave-like contours to increase surface airflow and move heat away from your body. Rather than blocking airflow like a flat slab, the swirled surface encourages ventilation across the foam's top layer, helping your mattress sleep feeling less warm.

• Gel infusion absorbs and distributes surface heat.
• Wave Dynamics-style swirls create channels for air circulation.
• 2-inch profile balances cooling with gentle contouring support.

Will the 2" topper still feel supportive for pressure relief?

Yes — this topper is designed to add a soft, contouring layer that eases pressure without creating deep sinkage. At 2 inches, it provides noticeable cushioning for shoulders and hips while preserving the underlying mattress’s support and alignment.

• Medium-soft memory foam conforms to body curves for pressure relief.
• Maintains mattress responsiveness beneath the topper.
• Works well on a variety of mattress types, including firmer surfaces.

How easy is it to get the topper set up and kept fresh?

The topper ships compressed in Zinus's smaller WonderBox for simple delivery and handling; once unboxed and unrolled it recovers its shape within about 72 hours. The foam is CertiPUR-US certified, which means low VOCs and safer indoor air quality, and only a short, normal foam odor may appear and then dissipate.

• Shipped in WonderBox for easier carrying and reduced footprint.
• Unroll and allow up to 72 hours for full expansion.
• CertiPUR-US certified foam for low emissions and durability.

Can this topper fit my sheets and last over time?

The 2" thickness is thin enough to fit under most standard and deep-pocket fitted sheets without altering sheet fit or mattress height dramatically. Zinus backs the topper with a 5-year limited warranty and uses durable foam intended to resist premature sagging when cared for properly.

• Compatible with standard and deep-pocket sheets.
• Durable memory foam construction with CertiPUR-US certification.
• Included 5-year limited warranty for peace of mind.
