Pro Adjustable inflatable lumbar cushion
Pump the lumbar support up, or let it down, for instant change in back curvature.
Pro Highly adjustable
Lots of adjustments, to get the perfect fit. Extremely comfortable even for long periods of sitting.
Pro Full length back with headrest
Having support for your back all the way up, and somewhere to rest your head, is very worthwhile for a chair you sit in for long periods of time.
But worth it for the hours you'll be sitting in it.
Con Arm rests not the strongest
Plastic arm rests are useful, but aren't as resilient as they might be, and the plastic can crack and break.
