The idea of park chairs equipped with built-in carbon monoxide (CO) detectors is intriguing, but as of now, such products are not widely available or commercially mainstream. Carbon monoxide detectors are typically installed in enclosed spaces like homes or garages, where CO buildup poses a significant risk. However, the concept aligns with the growing trend of "smart furniture" designed for public safety and convenience.

While standard park benches focus on durability and comfort, integrating air quality sensors—including CO detectors—could become a future innovation, especially in urban areas with high pollution levels. Some experimental designs and prototypes have explored combining seating with environmental monitoring, but mass production remains limited.

For now, visitors to parks should rely on traditional CO detectors in nearby buildings or portable personal devices if air quality is a concern. The development of multifunctional outdoor furniture, however, suggests that smarter, safer park amenities may soon emerge.
