But the Anthros V2 has been a pleasant surprise. It doesn't help that the V2 chair costs north of $2,000, though it seems to be on sale often enough for around $1,900. The Embody still holds a place in my heart, but the Anthros V2 might be the best chair for anyone looking to sharpen up their posture, especially if you've been dealing with back pain. The right knob moves the lumbar backrest forward and back, and the left knob handles the top. On my first day in the chair, I felt a little sore because it almost felt like the chair was pushing in.
