About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Dowinx
Office chair

Manufacturer’s product description

The Dowinx Big and Tall Office Chair is an ergonomically designed office chair for users who value high seating comfort, stability and flexibility. With a load capacity of up to 600 lbs, it is primarily aimed at people who are looking for a particularly robust yet comfortable chair for everyday use in their home office or workplace. The chair impresses with its wide seat, adjustable components and breathable mesh backrest.

In practical testing, the pleasant seating comfort was noted positively, as was the high-quality workmanship of the seat and backrest upholstery. Assembly was simple and straightforward.

The only negative points were the lack of a backrest height lock and minor flaws in the paint finish on the metal parts.

Overall, the Dowinx Chair delivers what the manufacturer promises and offers a convincing overall package for anyone looking for a durable and comfortable office chair – especially for longer periods of sitting.

  • Very high load capacity
  • Ergonomic design
  • Quick and easy assembly
  • Breathable back section
  • Slight chemical odour
  • Back height cannot be locked

The Dowinx Big and Tall Office Chair was delivered in a sturdy, stable cardboard box. The product was adequately protected by polystyrene elements and plastic packaging, as well as extensive use of cardboard. The product arrived undamaged: there were no visible scratches or damage caused by transport.
The individual parts, especially the screws, were neatly sorted into separate bags, which made assembly easier.
From an environmental perspective, Styrofoam could be dispensed with in future, but this type of packaging is common for furniture and ensures safe transport.
The entire delivery was complete: all necessary screws, tools (two Allen keys in sizes M5 and M6) and the larger components were included.
The enclosed instructions were clearly laid out, well illustrated and logically structured. Even users with little DIY experience can assemble the chair in 20 to 30 minutes without any problems. In addition, the manufacturer’s contact details and legal information are provided in the usual form and can be accessed digitally via a QR code. The overall first impression was very positive.

At first glance, the chair looks modern and functional. With its two colour options (black and white), it fits well into various interior styles. The surfaces of the seat and backrest are neatly finished, and the upholstery material appears durable and pleasantly soft. No open seams or manufacturing defects were noticed when checking the individual parts. Only a few metal parts in the frame area showed slight paint defects – however, these are not visible when assembled. Particularly noteworthy is the solid construction of the base and the castors, which run smoothly on different floors. The chair appears very stable overall. Although the armrests and headrest are made of plastic, they did not give cause for complaint during testing. As this is a durable piece of furniture, the sustainability rating is cautiously positive – however, further information on the origin or carbon footprint is not available.

In everyday use, the Dowinx office chair impresses with its overall high level of seating comfort and good functionality. The ergonomic shape noticeably relieves pressure on the back, especially during longer periods of work. Thanks to the adjustable backrest, lumbar support, armrests and headrest, the chair adapts well to different body shapes. The only criticism is that the backrest height cannot be fixed and can slip slightly with frequent use. The seat is pleasantly wide and thickly padded, which prevents pressure points. In tests, the breathability of the material proved to be a clear advantage over fully upholstered models – even after hours of use, the seat climate remains comfortable. The castors run smoothly and quietly on various floors, even on short carpets. The metal base provides excellent stability, giving the chair a secure feel.
The chair was quick and easy to assemble – all screws fit and the tools were included in the delivery. The chair took about 25 minutes to assemble completely. A damp cloth is sufficient for cleaning – we did not encounter any difficulties with either the plastic or the mesh fabric. A slight chemical smell was noticeable at first, but this dissipated after a short time. Overall, the chair largely meets the manufacturer’s specifications and offers good value for money for anyone who spends a lot of time at a desk.
