FAQs
Gaming chairs focus on long sitting sessions with features like headrests, lumbar pillows, and reclining backrests. Office chairs are usually designed for posture and professional work environments. The better choice depends on whether comfort for gaming or ergonomic support for work is the priority.
PU leather on a gaming chair typically lasts around 3–5 years with normal use and proper care. Regular cleaning and avoiding sharp objects can help extend its lifespan. Over time, frequent use and friction may cause peeling or cracking.
PU leather can sometimes trap heat because it is less breathable than fabric or mesh materials. During long sitting sessions, this may lead to sweating, especially in warm rooms. Using breathable seat covers or maintaining good airflow in the room can help reduce this issue.
