IIRC, the lowest-back-muscle-tension recline angle isn't actually 180° (laying completely flat) but actually 135° (legs forward, back and neck against a wedge. Or probably—in the ancestral environment—against the base of a tree.)

Anyone got a good ergonomic setup for achieving 135° recline, no-neck-flexion computing? (Besides buying that one ridiculous $5000 chair, I mean.)

Interesting! I haven't tried it yet, but perhaps foam wedges would be a cost effective approach? (typically used as yoga props)
