Desk/office chair for big guy

hello, i am looking for a solid, sturdy desk chair for my home office for a guy in the 400lb range. i don't have a budget in mind as i am broke right now but hoping to invest in a better chair once my income stabilizes. I don't care too much whether it rolls or not, and am open to alternatives to the typical desk chairs. in fact the last chair i had with wheels the legs bent and made the chair unusable. the chair was advertised as for up to 500lb but my fat ass still bent it. currently i am taking my dining room chair back and forth from the kitchen table to my desk. this is a workable solution for now but this chair is not comfortable for sitting in longer than an hour, much less a typical full 8-10 hour work day.

I'd prefer something that doesnt look ugly as all get out but like I said I am open to suggestions.

I prefer not to buy on amazon if possible.

thanks!
