I am taking my time on this. So far, I have liked the Lifeform chair at Relax the Back the best. Not having sat in a Herman Miller chair yet, so I reserve judgment. But until I can get one, I went to Office Depot. They had a sale on chairs and a coupong for today for 40% off one item. Found a chair there the Pro 3000 for $179, down to $149 and then 40% off so tax and total was a shade under $99.
Almost, like the Lifeform, in a way that a Hyundai is almost a Lexus. The Office Depot chair had arms that went up and down, and back and forth - Lifeform arms swing in and out, so it has the plus. Tilt forward, which is great because I can extend over the desk and still push my back fully against the seat back and lumbar support - could not do that with the chair I had. Raises up and down
The build quality on the Office Depot is not anything like the Lifeform. Also, the Lifeform has memory foam in the seat with, instead of what they call that waterfall seating, it has channels wear your legs rest in and hits you in the right spot a few inches from your knee. My dilemma is getting a mid back, regular back or the high back. I am thinking of the high back Lifeform because you can lean back and get a foot stool and it is almost like a zero gravity chair. Shut my eyes for 30 minutes and take a nap if I need to since the High back has that advantage. Drawback - the price is at least $1800 for the naugasuede as they call it, or a fabric one. Leather, add $800 more
