The ERWIN M. LUSINI Solutions GmbH Siena is a grey fitted sheet designed for mattresses measuring 90x200 cm. It is crafted from a percale weave consisting of 80% cotton and 20% polyester, providing a balanced fabric weight of approximately 120 g/m². To ensure the sheet stays securely in place on your bed, it features elastic corners that create a snug fit. This bedding is certified under OEKO-TEX® STANDARD 100, confirming it meets strict safety requirements for harmful substances. For maintenance, you can wash the fabric at 60 °C and tumble dry it on a normal setting. While it is not wrinkle-resistant, ironing at 150 °C will give you a smooth, crisp finish. To preserve the material, avoid using chlorine bleach or dry-cleaning services.
