They are the best answer to this question. While I'm waiting to move house and have a dedicated working space, I'm currently working in an Eames recliner with the laptop on my lap. While somewhat unconventional, I've actually had way fewer back and neck problems in the last year than when I used to sit at a desk in an office. Once I've moved house though, it'll be a used Herman Miller, probably an Aeron.
