The ERWIN M. LUSINI Siena fitted sheet in smoky blue is designed to provide a secure and tidy fit for a 90x200 cm mattress thanks to its elastic corners. It is crafted from a percale weave consisting of 80% cotton and 20% polyester, with a weight of approximately 120 g/m² that balances softness and durability. To maintain the quality of the fabric, you can wash it at 60 °C and tumble dry it on a normal setting, though you should avoid chlorine bleach and dry-cleaning. Because this material is not wrinkle-resistant, ironing at 150 °C is necessary to achieve a smooth, crisp look on your bed. For peace of mind regarding textile safety, the sheet carries the OEKO-TEX® STANDARD 100 certification.
