Where can I buy this ergonomic office chair at the lowest price in Kochi?

I’m currently looking to purchase an ergonomic office chair similar to the one in the image. I’ve seen it priced around ₹7,000 to ₹8,000 in some offline stores, but I’d like to know if anyone here knows where I can find this for a lower price in Kochi. I prefer buying it offline as I want to personally try it out before purchasing. If you’ve bought a similar chair recently or have any recommendations for stores offering good deals on ergonomic chairs, please let me know.
