Our practical test confirms the high material quality of the SCHOELA® sleeping bonnet. The silk material used is flawless, soft and shows no irregularities. It feels uniformly soft and comfortable. The fit of the bonnet is excellent thanks to the infinitely adjustable fastening. It adapts to different head sizes and stays in place even when moving around at night, without leaving pressure marks. This fastener is an innovative unique selling point compared to other manufacturers.

Wearing comfort is extremely high: the bonnet optimally regulates temperature and moisture and is very comfortable even when worn for long periods. Slip resistance was also tested. Although the bonnet can slip slightly during very restless sleep, it stays in place for the most part and therefore fulfils its function.

The seams of the bonnet are hard-wearing and show no signs of wear, even after intensive use. The Oeko-Tex® Standard 100 certification also guarantees that the product is free from harmful substances and fulfils the highest quality requirements.
The tested bonnet is a further development of the previous sleeping bonnet, which has been significantly improved in line with customer requirements.

Overall, it can be said that the SCHOELA® sleeping bonnet largely fulfils the manufacturer’s advertising promises. The combination of high-quality material, excellent fit and high wearing comfort makes the bonnet a reliable and luxurious everyday companion .

*Themaximum score is 100 points

The product was significantly improved and adapted in July 2024. Therefore, the existing reviews do not sufficiently reflect the advantages and disadvantages of the product, so this point is neglected in the evaluation.

Prices of up to €55.99 are charged on the Internet for equivalent products. Very affordable products are available from as little as € 29.99 . The Hair Wonder sleeping bonnet from SCHOELA® is therefore currently in the upper price segment with a price of €49.90. For the quality and performance received, the price-performance ratio is very good.
