It's from this luxurious furniture store called Amaçon Primé :) Link
It's an older office chair from Poly&Bark but can still be purchased through Amazon.
Here is the link. It is very sturdy and comfortable but I mostly bought it for aesthetic. It is much bigger than I thought it would be so that's also a plus. The wheels on this chair aren't the best but I'm not too nit picky on that. Overall, solid chair.
