Feluna®
Sleeping mask

The Feluna® sleep mask is the ideal accessory for a restful sleep at home or when traveling. It allows you to sleep comfortably even when it is not completely dark and noticeably improves the quality of your sleep . With its 100% satisfaction promise, the Feluna® brand stands for high quality and customer satisfaction. The sleep mask impresses with its perfect ergonomics, which adapts individually to every face. The elastic and adjustable rubber straps as well as the special ergonomic shape and additional nose pads ensure a perfect fit. Thanks to the opaque material and adjustable size, the sleep mask offers almost complete blackout. Studies have shown that sleep is more restful in the dark. The high-quality materials, such as the silk-like satin and the firmly sewn-in foam padding, ensure a comfortable and restful sleep without sweating. In addition, the cooling cushion supplied can be inserted or removed as required. Pre-chilled in the freezer, it can help to reduce bags under the eyes, dark circles and tired eyes as well as relieve migraines and headaches.

Advantages

✅ Improved sleep quality
✅ Perfect ergonomics for individual adjustment
Optional cooling cushion for additional relaxation
✅ Almost complete darkening

Disadvantages

❌ No sustainable product packaging

The test

General information

To give you a quick overview, we work with a points system. The maximum achievable score per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weighting.

The first impression

Packaging and contents

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

*The maximum score is 100 points

The first impression of the product is very positive. The packaging is attractive and effectively protects the product from damage during transportation. The use of recyclable materials for the outer packaging is particularly commendable. A more sustainable solution could be considered for the product packaging. The contents of the packaging are complete and in perfect condition. The sleep mask and cooling pad are of high quality and promise a pleasant use. Only the lack of instructions for use could be problematic for some users, but the use of the sleep mask is intuitive and requires no further explanation. Overall, the first impression of the product is very positive and suggests good quality.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the workmanship of the products. How high quality are the materials used? Are the look and feel satisfactory?

Product packaging

The product impresses with its visual appearance as soon as you touch it. The workmanship is of high quality and is expected to last a long time. The material consists of 70% polyester, 20% cotton and 10% polyamide. There is a slight polyester smell when opening the packaging, but this is no longer noticeable once the sleep mask is put on. The stability of the product is very good, so that it does not lose its shape even after prolonged use. Unfortunately, there is no information on the sustainability of the product, which could be a drawback for environmentally conscious consumers. On the other hand, it is positive that the packaging is also suitable for giving as a gift and that different color variants are available from the manufacturer. Overall, the product makes a high-quality and appealing impression, both in terms of workmanship and appearance.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

*The maximum score is 100 points

Our practical test has shown that the manufacturer keeps its advertising promises regarding the sleep mask. The mask is very comfortable to wear and does not cause any pressure points or discomfort even when worn for long periods. The cooling effect provided by the cool pack is pleasant and lasts for a longer period of time. The light shield works well and ensures complete darkness. The fit of the mask is good and adapts to different head sizes and shapes without slipping during sleep. Cleaning and care are simple and straightforward, as the mask can be washed at 30 degrees and tumble dried. All in all, the sleep mask meets expectations and delivers what the manufacturer promises.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good100 points
Rating cut3.8 out of 5.0 on Amazon40 points
Total70 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 3.8 stars. Customers complain that the ribbon comes loose quickly and the seam opens. The unpleasant smell is also criticized. On the other hand, the relief of migraine pain and the ease of falling asleep due to the cooling of the eyes and darkness are rated positively . In our practical test, we were able to confirm that the sleep mask is very effective, and we cannot confirm a lack of quality.

Prices of up to €15.99 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €5.89. The Feluna® sleep mask is therefore currently in the middle price segment with a price of €7.99. For the quality and performance received, the price-performance ratio is reasonable.
