Wolkenfeld
Fitted sheet 25-40cm

The Wolkenfeld fitted sheet in sizes 90×200 cm to 100×220 cm is particularly suitable for use with box-spring and waterbeds. It has been specially developed for mattresses with a height of up to 40 cm and, thanks to its strong elasticated band, offers a wrinkle-free and secure hold, even during restless sleep.
The fitted sheet is made of 95% cotton and 5% Lycra, which makes it particularly breathable, elastic and dimensionally stable. The fabric density of 190 g/m² makes the sheet more robust than many other products of this type and ensures a pleasant sleeping environment. The anthracite-coloured look gives the bed an elegant and modern touch.
The company Wolkenfeld, based on Lake Constance, attaches great importance to the quality of its products and to sustainability. The fitted sheet is certified in accordance with the MADE IN GREEN by Oeko-Tex standard, which guarantees environmentally friendly and socially responsible production.
In addition to its practical and easy-care properties, the fitted sheet also adds aesthetic value to any bedroom. It is easy to fit and stays in place even on high mattresses thanks to the strong elasticated band.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.3 stars. In some cases, the fabric is criticised for being too thin . On the other hand, the high elasticity and good quality are emphasised positively. In our practical test, we were able to confirm that the fit and quality of the fitted sheet is well received by customers. We do not believe that consumer criticism of the fabric of the sheet is justified.

Prices of up to €79.99 are charged on the Internet for equivalent products. Very cheap products are available from as little as €12.34 . The fitted sheet from Wolkenfeld is therefore currently in the middle price segment with a price of €39.99. For the quality and performance received, the price-performance ratio is very good.
