Breathable VORA Zzz️ Technology: VORA Zzz️ Additive Technology is considered one of the most technologically significant products in recent years. Our mattress topper uses Breathable VORA Zzz️ Additive Technology with Ultra-high Airflow Memory Foam, which helps buyers get their coolest sleep yet with its impressive moisture-wicking capabilities.High Breathability and Permeability: Breathable VORA Zzz, an innovative foam empowered by ComforScience, quickly wicks moisture, keeping the body cool, and enabling comfortable and restorative sleep. This technology also changes the structure of traditional foam into a dense "breathing pore" structure, which ensures high moisture permeability, giving you a cool and dry surface to sleep on all night long. No more sweaty nights!Better Comfort and Support for Pain-free Sleep: Our VORA Zzz️ Technology with high-density foam at the bottom provides optimum back support and contours your body for exceptional comfort. Get ready to wake up feeling refreshed and energetic every morning. Our mattress is designed to optimize air flow and reduce trapped body heat. An additional loft and cooling bamboo blend fabric ensure deep, relaxed sleep.Machine Washable Bamboo Fiber Cover: The water absorption capacity of bamboo fiber is three times that of cotton. Large and small oval-shaped pores with a strong capillary effect absorb and evaporate large amounts of water instantly. This makes it more breathable, cooling, and durable along with being removable and machine washable for easy cleaning care.Like all newly manufactured items, your new mattress topper may have a slight smell right after you unwrap it. However, the smell should go away quite quickly. Don't worry! The smell is not associated with any harmful chemicals since all of our foams are CertiPUR-US certified. For the first few days, or until the smell goes away, let your mattress topper breathe as much as possible.
