NOT for BIG people. Actually they should sell chairs made specifically for BIG persons - I would estimate up to 275lbs. maybe? But I wouldn't try 350lbs. Just believe they should make this same chair but with thicker heavier duty parts for people who are not Keebler elves :)Perfect for me 5'-6" and under 190lbs.So if your bigger than that you may find this chair less than desirable? Feels like a very nice drivers seat, don't play video games - but it's great for computer work.The ARMS of the chair were NOT easy to attach, screws difficult to align and screw in. I believe this could be a point of failure because proper alignment very iffy.Other than that assembly was easy peasy, but I'm a DIY type.Overall not a bad purchase. Could have been made with some sturdier plastic. Immediately noticed the arms were a little loose and the padding can get hard after awhile of arm rest. I went to lean all the way back and heard a crack, unsure if it was from the bolts setting in or the wood backing. And after about 3 months of use one of the wheels had bent the plastic it snaps into and falls out on occasion.Definitely worth the price in comparison to the pricey well known brand racer chairs.Easy to assemble. amazing lookMy son had this chair less than 6 months and the wheel snapped off the base rendering it completely useless. I paid 120 dollars for this only for it to break. My son isn't even a big kid, he's about 5'7" and under 200 lbs so I don't understand how it could have just broken like it did! Don't buy it, waste of money. And it was a pain in the butt to assemble.Edit: The customer service team has been completely excellent. They sent me a new five star base, but Im having issues getting the gas lift to separate from the old base which broke, which seems to be a common design flaw with the plastic bases. So they offered to help me get a new gas lift and I am indeed okay with this as I can put the new gas lift on the new base and we can just pull the gas lift off the old base without worrying about getting the old 5 star off. Will update once that's done.Real Sturdy and nice to sit in/on.not much back support, it dont roll good over my carpet. but serves its purpose , next one im going to just spend extra and get a real good gamming chair, im big on comfort .. i;ll give this one to my son, her likes it loltook some time to mount, but afterwards, the chair is very confortable, easy to use.I've had it less than a day, but it's a definite improvement over what I had.
