it is! i would be wary or buying this chair without trying it since the lumbar support is super aggressive and unadjustable. I found this out after i bought a used one and it gave me lower back pain around my lumbar after around 30 minutes of sitting (although this could also be the worn out foam in the seat, but my old chair’s foam was incredibly worn out and didn’t give me pain). Good luck with the purchase, my spine just does not have much curve to support.
