So after a month or so of checking chairs and looking for a good work / gaming chair I found myself buying the mirra 2, at the store I tested all the Herman miller lineup and I gravitated towards the mirra and the Aeron, in my country (Israel) they are both much more expensive than it seems to be in the US because of shipment / taxes so the aeron came at around 1875 USD and the mirra at 1375, I liked them both about the same, each with its own advantage but decided to go for the mirra2, for its lower price point, I am using it for 2 weeks now and it has done wonders to my back pain, had an injury a few months ago at the gym and I’ve had back pains ever since, from the moment I sat in it I felt I’m finally sitting like my body should sit, my back pain is far less noticeable and I feel it diminishing every day, I am a programmer and an avid gamer so I sit quite a lot every day (work from home due to COVID) anyway that’s my recommendation, for anyone who may think about the mirra I suggest trying it out before but definitely think about it as an option
