Use toppers when your existing mattress appears to be too tough, when you are sleeping on folded beds or extra beds, or whenever you want to increase your comfort and sleep quality. By using the topper in combination with an existing mattress or a new mattress of low quality you get maximum comfort with minimal investment. Covers are removable and washable at 40°C. By keeping the cleanliness of the bedding regularly, you will avoid dirt on the cover and the core of the overhead. We recommend turning and rotating the overpass. By following these instructions, you can extend the product's quality and longevity to complement your sleep.
