Welldora
Four-season duvet

In our test, the 4-season comforter from Welldora made a very good impression. The materials used are high-quality, dimensionally stable and have no seam defects. The product is also washable up to 60 degrees, certified to Oeko-Tex Standard 100 and scored “very good” in the Dermatest. The blanket retains its shape and color even after washing.
Changing from a summer to a winter comforter is very easy thanks to the many attached buttons. The hypoallergenic, breathable microfiber fabric reduces the penetration of dander and dust and counteracts dust mites. At night, there is no noise, no slipping and no unpleasant creases.

The test

General information

We have looked at and tested the product in detail in a practical test. In the following, we take a closer look at the features and impressions. The product is subjected to our test procedure from the packaging, materials and quality to the range of functions and handling.
To give you a quick overview, we work with a points system. The maximum possible number of points per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weightings.

The first impression

Packaging and labeling

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 ensured.

Vierjahreszeitendecke Verpackung
Four-season comforter packaging

The 4-season comforter from Welldora arrived for our test in a typical shipping box. This was undamaged on arrival and could be easily opened by removing the adhesive strip. Inside the product box, the four-season comforter was packed in a plastic and fabric bag. This type of packaging ensured that the product was optimally protected from external influences and could be shipped hygienically and in a space-saving manner. Product protection was therefore fully guaranteed and the four-season comforter was delivered in perfect condition.
The packaging is partially recyclable. However, the plastic bag is not recyclable. Nevertheless, the presentation of the product makes a very good impression.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The four-season comforter is hygienically packaged in foil and also in a fabric bag. The fabric bag contains a QR code for the 130-page e-book “Health Elixir Sleep”. The product is made of 100% polyester. Instructions for use are not required. However, the manufacturer includes an information leaflet with the product, which contains answers to product-related questions, the intended use and care instructions. Washing instructions, product information and contact details can be found on the sewn-in label, the letter and the plastic film. However, there is no customer hotline. Nevertheless, we consider this a very good way to send a product.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

First of all, the 4-season comforter makes a very good visual impression. The material is dimensionally stable and there are no visible seam defects. The product also impresses with its simple, timeless design.
Welldora has thought about sustainability , as the four-season comforter is washable at 60 degrees, the product is certified according to Oeko-Tex Standard 100 and was rated “very good” in the Dermatest. The materials used also appear to be of very high quality, which is why we expect it to last a long time.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

We washed the product before first use. We can therefore confirm that the 4-season comforter retains its original shape and color after washing at 60 degrees. However, due to the packaging, the blanket should be left to rest for 48 hours before first use.
The buttons allow the blanket to be quickly converted from a summer to a winter blanket. The hypoallergenic, breathable microfiber fabric prevents the penetration of dander and dust and counteracts dust mites. During the night, we didn’t notice any noises, slipping or uncomfortable creases. We also didn’t sweat more than normal. One test subject with a dust mite allergy reported fewer symptoms and more restful sleep during the test period.
Customers can currently choose between the sizes 135 x 200, 155 x 220, 200 x 200 and 220 x 240 cm.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at 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 examine consumer ratings and check whether the critical and positive reviews are actually justified.

Prices of up to €157 are charged on the internet for equivalent products. Very inexpensive products are available from as little as €32. The Welldora four-year comforter (135 x 200 cm) is therefore in the middle price segment with a current price of €39.99. Consequently, the price ratio is very good for the quality and scope of services you get.
