It is an allergy-friendly product that is IGR-tested. This seal is awarded to ergonomic products. The pillow adapts perfectly to the neck and shoulder structure. This ensures very pleasant sleeping comfort. The removable cover is certified to Oeko Tex Standard 100, which confirms that the product is free from harmful substances .

The first impression

The 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.

The side sleeper pillow from Knerst GmbH is delivered in a classic shipping box. The pillow is packed in an additional cardboard box. It is also delivered rolled up in a fabric bag .
This ensures that the product is fully protected and the children’s cushion is in perfect condition. It made a very good first impression and could be used straight away without any further effort.
It should be particularly emphasized that only recyclable, renewable materials (paper/cardboard) were used for the outer packaging (shipping box/product packaging).

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 packaging contains a flyer next to the side sleeper pillow . There are no instructions for use, but this is not necessary as the handling is intuitive . Unfortunately, the packaging does not state what materials the pillow is made of. There is a care instruction on the product, which is unfortunately inadequate . The washing symbol does not indicate the number of degrees.
The manufacturer’s contact details with support email and address are stated on the product packaging. A telephone number is given on the enclosed flyer . The flyer informs the customer that this is a climate-neutral product and contains information on frequently asked questions.
All in all, this is a well thought-out and customer-friendly way of presenting and sending the product.

The side sleeper pillow from Knerst makes a very good visual impression in the test. In addition to its simple design, it has no manufacturing defects and is of high quality.
The product does not smell of chemicals, so it does not need to be aired and can be used straight away. However, the manufacturer recommends leaving the product to develop for one to two days. It is particularly noteworthy that the pillow has been manufactured in accordance with the OEKO Tex Standard 100. This means that all components of the pillow are harmless to health as they have been tested for harmful substances.
With this certified “climate-neutral product“, all CO2 emissions are offset by a certified climate protection project, making it completely CO2-neutral.

This is what our practical test showed

We liked the side sleeper pillow with memory foam from Knerst very much in the test. The sleeping comfort is very pleasant and offers ideal support for the head and neck thanks to the correct height of the pillow. Thanks to the special foam (memory foam), the pillow offers optimum pressure relief and adapts to the neck and shoulder structure. The special neck arch and head hollow relieve pressure on the cervical spine and reduce tension. The product properties were confirmed in our test, the pillow is ideal for side sleepers and offers very pleasant sleeping comfort. The removable cover is machine washable and has been awarded the Oeko-Tex Standard 100. The pillow is hypoallergenic and free of harmful substances and is manufactured in Europe. The IGR certification of the product should also be emphasized. This label is awarded for ergonomic products. Due to the size of 53×40 cm, it is difficult to find a suitable cover. Nevertheless, it is a very good product.
