Description
xTwo-layer comfort in one accessible upgrade
The DUMOS Dual Layer 4-Inch Mattress Topper for a Full bed blends a 2-inch cooling gel-infused memory foam base with a 2-inch breathable pillow-top layer. This two-in-one design creates a plush, airy surface that supports your body while promoting airflow for a fresher night’s sleep.
What makes this topper feel exceptional
- Contour with relief: The memory foam base eases pressure points and helps align the spine, offering a balanced, medium-firm feel that can refresh older mattresses.
- Soft, cool surface: A breathable pillow-top layer delivers a silky touch that stays comfortable as temperatures rise.
- Airflow-driven comfort: Gel-infused foam and the ventilated cover work together to help dissipate heat and maintain surface freshness.
- Value and versatility: It can revive a variety of mattress types, adding comfort without a full replacement.
Cooling, breathable comfort you can feel
- Silky surface: The pillow-top cover uses a special weave for a cool-to-the-touch sensation and improved airflow.
- Heat management: Gel-infused memory foam moves heat away from your body so the surface stays comfortable longer.
Fit, safety, and care you can trust
- Secure fit: An elastic deep-pocket skirt accommodates mattresses up to 21 inches thick, keeping the topper in place.
- Safety and quality: CertiPUR-US certified memory foam and OEKO-TEX Standard 100 textiles, free of fiberglass and harsh chemicals.
- Care and expansion: Vacuum-packed for shipping; lay flat in a ventilated area for 48–72 hours to fully expand, off-gas, and restore fluffiness.
