Using the chair for about 10 days now - 8-10 hours work schedule. Its been very comfortable for my lower back - where it presses in for support. The wheel movement is quite free considering the fact that I am 104 Kgs. Previously I had been using similar Nilkamal Office chair and they had given me good service for years. Though its too early to comment but I hope this too shall remain sturdy and comfortable for a long time to come. I have always found the Nilkamal Brand synonymous with quality. Kudos to them.
