Bowthy Big and Tall Office Chair 300lbs Computer Ergonomic Desk Chair with Adjustable Lumbar Support High Back Executive Task Swivel Leather Chair (Black)

Q: What is the max loading? I am 6' 4'' tall and weigh 290Lbs.Trully need a big and tall chair.

I believe it’s 400 pounds. I am 6‘3“ 260 pounds and the chair fits great.

Q: Do the wheels work on hardwood floors?

I wouldn't recommend using the casters that come with the chair. I just ended up buying aftermarket casters for $43. Also,the manufacturer is aware that their casters are bad or they've had problems with them. The chair is comfortable with the lumbar support and the height is perfect for me at 6'1".
