I’m WFH in Utah, and would be looking for an ergonomic chair after two lower back disc surgeries this year. I’ve read that the Herman Miller Aeron would be great for my situation, but they’re very expensive new. Anyone know of any local warehouse stores that might sell them refurbished or used? I’d like to use HSA money as I’ve got a letter of medical necessity, so buying one off KSL would prohibit that from a receipt standpoint unless it was a retailer. I’m also curious if anyone has an alternative - there’s so many others online with varying opinions.
