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?

During the extensive practical test of the self-adhesive magnetic tape A+B from DANJOY®, it became clear that the manufacturer keeps its advertising promises. Installation is extremely straightforward: first clean the surface, remove the protective film and apply the tape. It adheres immediately and securely to the surface by gently pressing it on. The cuttability of the magnetic tape was particularly impressive in the test – it could be easily and precisely cut to the desired size to meet individual requirements.
The tape’s adhesion proved to be reliable and guaranteed a secure hold for objects such as a fly screen. Interestingly, the magnetic tape could be removed without leaving any residue with a wooden spatula during the practical test, despite the lack of information from the manufacturer. This flexibility and user-friendliness contribute to the positive overall assessment of the self-adhesive magnetic tape A+B from DANJOY®, which proved its quality and functionality in the practical test.

As part of our product review, we took a closer look at the electrically adjustable arm chair from FlexiSpot . This armchair was developed to combine comfortable seating and functionality. It consists of a sturdy iron frame and generous upholstery, ensuring a stable base and comfortable seating. The ergonomic shape supports a healthy sitting posture. The faux leather upholstery is easy to clean, scratch and abrasion resistant and therefore suitable for everyday use. Operation via two buttons proved to be simple and intuitive in the test. The backrest and footrest can be individually adjusted. An integrated USB charging port provides additional convenience.

  • First-class comfort
  • USB connection
  • Quick and easy adjustment of the backrests
  • Simple assembly
  • PU leather

The packaging of the set leaves a positive first impression. The shipping carton is made exclusively from recyclable and renewable materials such as paper and cardboard. The compact design helps to minimize waste and avoids unnecessary packaging material. Only the use of plastic film on the inside could be reconsidered. Although it protects the product, the use of recyclable material would be desirable.

The armchair is supplied in 2 packages. The scope of delivery includes the armchair in 4 parts (seat, backrest and the 2 side parts with armrests), the power supply unit and an instruction manual. The completeness and perfect condition of the contents meet expectations.

At first glance, the armchair shows a solid construction and high-quality workmanship. The choice of materials, including the sturdy iron frame and the generous upholstery, suggest durability and comfort.

The simple design enables unobtrusive integration into various living areas. The coffee brown, cream white and orange color options offer flexibility for different furnishing styles. The rounded shape, wide armrests and soft upholstery promise pleasant seating comfort and modern aesthetics.

The stability of the chair has been carefully tested to ensure safe use in all backrest positions. Operation is simple: the footrest and backrest can be adjusted with just two buttons. An integrated USB port provides additional convenience.

The use of PU leather is not sustainable, but thanks to improved materials, FlexiSpot promises a long service life. The water-repellent, abrasion and scratch-resistant PU leather contributes to the longevity of the chair and makes maintenance easier.

Our detailed evaluation of the FlexiSpot electrically adjustable armchair was very positive. Assembly was quick and easy thanks to the easy-to-understand instructions and the careful packaging of the individual parts. The chair proved to be stable and reliable both with the backrest folded in and out.

The simple adjustment of the chair with just two buttons enables individual adjustment of the footrest and backrest. The movements are smooth and quiet.

The chair offers generous comfort with upholstery, armrests and cushions that support a natural posture and prevent tension. The additional function of a USB charging port increases comfort.

Cleaning is straightforward thanks to the improved PU leather, which retains its quality even after repeated cleaning. However, a scratch test in the stability category showed slight marks when the material was subjected to heavy pressure. Nevertheless, FlexiSpot promises long-lasting and easy-care use thanks to the improved PU leather.

Overall, the FlexiSpot armchair is a reliable choice for users looking for a comfortable and functional piece of furniture.
