"BREATHABLE SLEEP: The upper foam layer provides softness, while the lower layer of high-density foam provides grip. Optimal sleeping comfort: the new generation Comfort Foam Core adapts perfectly to the body and offers comfort and flexibility for side, back and stomach sleepers. Wake up refreshed in the morning. Sophisticated design: our mattress covers are non-slip thanks to non-slip granules at the bottom and four straps for attaching to the corners. The cover is removable and can be washed at 60 °C. Buy with confidence: the topper has passed the strict certifications Oeko-Tex (see details in the sustainability features below) and CertiPUR-US (see details by searching for ""Novilla"" on the CertiPUR website). Excellent service: Novilla knows that your body needs time to get used to your new mattress. That's why we offer a 30-night probationary period. If you have any questions, please feel free to contact us!"
