I ignored smart seating solutions for my home office for years because what I've had has worked alright, but for the past year I've been using an Aeron chair for work during the day at the office, and my home situation got to the point where I would avoid using my home computer.
No longer. The SAYL is a fascinating (newish) chair by Herman Miller with a reasonable price. The frameless back is not only "a new leap" in chair design, but it drives costs down by using fewer parts and it actually is pretty comfortable.
I don't want to get into it too much, since it is just a chair, but suffice to say it's pretty and I can barely tell the difference between this and the Aeron (and honestly, I kind of like this one better).
