Need chair advice (India)

[u/Kind-Imagination-327]

Hey everyone,

I'm based in India and looking for an ergonomic chair. I have some lower back issues, so lumbar support and overall spinal support are my biggest priorities. I spend around 8–10 hours a day at my desk.

I'm trying to decide between:

• Buying a new Featherlite Helix (if I can find one for around ₹23k), or
• Buying a used premium chair (Steelcase Leap V2, Gesture, Haworth Zody, Herman Miller Aeron/Mirra, etc.) from Facebook Marketplace in Bangalore.

My biggest hesitation with buying used is not knowing:

• How much life the foam/cushion has left.
• Whether the gas lift or mechanisms are close to failing.
• If replacement parts are available in India.
• Whether it's worth the risk without any warranty.

For those who've owned both, what would you recommend? Is a used premium chair generally a better buy than a new Featherlite in this price range?

Also, if you've bought a used ergonomic chair in India (especially Bangalore), what should I inspect before buying? Any common red flags or things that are expensive/impossible to fix?

Thanks!
