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: X50, belonging to category: Stacking Chair

### Response:
The X chair, which already won an award in 2018, was further developed into the stackable X50 product series and now also includes a high stool, a chair with armrests and a model with an easy-to-mount writing top. The seats and backrests of the chairs, weighing only 4.5 kg each, are elastic and adaptive to individual body contours. The distinctive design feature of the series is the aesthetic contrast of tubular frame and elastomer resin surfaces. This simple construction also allows complete disassembly for full recycling of all materials and easy maintenance.
