Manufacturer’s product description
The Dowinx QL-66B3 XXL office chair we tested is aimed at users who place particular value on high seating comfort, stability, and generous dimensions . According to the manufacturer, it is designed for a maximum load of up to 180 kg and combines a wide seat with a large backrest. The features are complemented by an integrated 2-in-1 lumbar cushion with massage function, height adjustment via gas spring, a 360° swivel function, and smooth-running casters for various floor coverings.
In practical testing, the office chair impressed above all with its high level of seating comfort and sturdy workmanship. The generous dimensions offer plenty of space and support, while the massage cushion noticeably increases comfort during longer periods of sitting. The chair is stable, easy to move, and blends inconspicuously into both office and home office environments with its understated design.
There is room for improvement in the adjustment mechanisms of the armrests and headrest, which offer only limited adjustment options. In addition, the packaging material used could be made more sustainable, as the high proportion of plastic is no longer appropriate from an ecological point of view.
Overall, the XXL office chair is a comfortable, durable, and practical work chair with clear strengths in terms of seating comfort and stability. It is a compelling solution for users who value plenty of space, a high load capacity, and additional comfort.

The office chair’s packaging proved to be sturdy and well designed in our test. The robust outer carton generally offers reliable protection against transport damage, but did show a few scratches and small holes after transport. Inside, all parts are arranged compactly and securely . All components – from the backrest to the screws – are wrapped in plastic film. Although this provides effective protection against scratches, it does result in a high proportion of plastic. From an ecological point of view, the use of more sustainable materials would be desirable in order to reduce the amount of plastic. Despite the external damage to the packaging, all product components were complete , well and securely stowed, and showed no damage or scratches. The enclosed multilingual instructions were understandable and made assembly much easier. Overall, the packaging offers solid product protection and makes a good overall impression. However, the main potential for improvement lies in the use of packaging materials.

The QL-66B3 office chair impressed in practical testing with its high level of seating comfort and solid workmanship. The generous, voluminous backrest offers a successful combination of supportive padding and comfort. This makes even prolonged sitting comfortable. The contoured seat cushion distributes body weight evenly and the integrated massage cushion specifically relaxes the lumbar spine. This noticeably increases comfort during longer work sessions. Overall , the chair is comfortable and provides good support. The adjustment mechanisms worked reliably. The height adjustment via the gas spring is smooth, the backrest can be locked in a limited range, and the 360° swivel function and casters run smoothly and evenly on carpet, laminate, and tile. The plastic casters are not completely silent, but they move quietly enough for everyday use. The armrests are stable and comfortable. They can be adjusted in height, but do not offer any further adjustment options in terms of width or angle. The softly padded headrest provides comfortable support for the neck, but cannot be adjusted or tilted, which limits the adjustment options.
Overall, the XXL office chair proved to be a very comfortable, stable, and functional work chair in the test. Particularly noteworthy are the generous seat, the ergonomic backrest, and the massage cushion, which specifically promotes relaxation. The limited adjustment options for the armrests and headrest are only minor drawbacks when purchasing this office chair.
