The seat started poking up and then seam split after about a year and 3 months. (My last office chair lasted 14 years.) I don't know if there is a warranty, but I will look for one! Very disappointing because otherwise it was a good solid chair.
My old chair lasted so long but was getting crappy. Got this one and wow. So much better than what I had. Love the high back on it, it’s comfort and the price. So happy I finally updated. I am 5’6” female and weigh 140. This chair is perfect for me. I don’t know how it will be for someone bigger or heavier but it seems pretty sturdy. Test it in the store, you’ll love it!
