I tried to find my chair, but I can't locate it on the office depot website. What I can say is that it is one of those purchases where you have to try out the chair before purchase. I went to various stores and would sit in each of the chairs without looking at the prices and then after I identified those that felt comfortable whittled it down from there. I didn't notice a difference between 600$ chairs and 250$ chairs tbh. After you find the chair you are looking for make sure to find it on their website. I saved 100 bucks because they had to price match their website.
In the process of trying to find my specific chair, I did come across this chair, which I feel struck me as your chair-spirit-animal. As the video on their website states the seat is comprised of fire retardant foam, which if I know you like I
think I do, which I don't, is EXACTLY what you are looking for.
