The base completely broke after 8 months of use. I use this for a normal office chair and work from home. I bought the extended warranty but the part they sent is impossible to replace without special tools and instructions not provided with the chair. It's great for occasional use but it's not durable and won't even last a year as an office chair.
Thank you very much for asking me about the CHAIR I have now. So far I've been happy and satisfied with the product! I hope it would be fine for some times!!
