This chair is as comfortable as it looks.  I gave it five stars just for its lumbar support alone.  I am a work-from-home legal transcriptionist and I spend hours upon hours sitting.  I have tried numerous other chairs claiming to have lumbar support, but I would still have to use a separate lumbar support pillow, and even then my back would start to hurt.  However, with the Serta Works Ergonomic Executive Chair there is no need for an extra lumbar support pillow.  I am so thrilled to have this chair!
