What are the ergonomic challenges of rigid PVC outdoor sofas?

Rigid PVC outdoor sofas, while durable and weather-resistant, often present several ergonomic challenges that can affect user comfort. The primary issue is the lack of flexibility in the material, which fails to conform to the body's natural curves, leading to discomfort during prolonged sitting. Additionally, rigid PVC does not provide adequate cushioning or support, potentially causing strain on the back and hips. The fixed design of these sofas may also limit adjustability, making it difficult to find an optimal seating position. Furthermore, the hard surface can become uncomfortably hot or cold depending on the weather, further reducing comfort. To address these challenges, manufacturers may incorporate padded cushions or ergonomic design elements, but these solutions often come at a higher cost. Understanding these limitations can help consumers make better-informed decisions when selecting outdoor furniture.
