Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: W70, belonging to category: Conference Chair

### Response:
The focal point of the W70 conference chair is the upper part made of solid plastic. Its backrest and seat surface were cast as a whole in one single operation, lending the chair a high degree of stability and its distinctive contouring. Thanks to welting technology, the frame of the backrest can be covered by a wide variety of fabrics, from leather or felt to a breathable mesh cover. The Dondola®³ technology is integrated invisibly and enables sitting dynamically, which actively prevents back strain by constantly facilitating micro movements.
