Extremely strong spring on the tilt back position. I have adjusted the control to the least strength or tension and to lean back to put me feet up is a lot of work. I’m constantly leaning back pushing back so I’m afraid it will wear out the cushion effect because to lean back I must equal the weight of a 200 pound person.. I’m only 155 pounds so I must exert myself constantly or the chair will go back to standard upright position. Your star rating is stuck on 5 I would only rate the chair as a 3 It looks nice. The sales people say the warranty doesn’t cover the covering material. So if the plastic starts to flake off like my last chair after 3 years it’s not covered.
My wife has a smaller version of this chair in our home office and I bought this one for myself thinking it was going to be an exact match to hers. Turns out the Kelburn is significantly bigger but also significantly more comfortable! It was pretty much exactly the same color (brown leather) as my wife’s chair so they match well enough. In any case I have had lifelong back and neck problems so I am really finicky about chair comfort and the Kelburne passes with flying colors. I spend at least 8 hours per day sitting in this thing and have never felt fatigue or discomfort in my back or neck. Purchased on sale for around $70 so it’s been a great value.
