I am skeptical having compared all these measurements time and again. I have a 38" seat to top of head measurement. Very unusual as a 35 year salelady pointed out yesterday. I sit in these massive chairs and my periscope is fully deployed above highest point of the chair. I look at seat hgt to top measure on the chairs as a reference but its hard to compute when sinking in some as well. I would be thoroughly satisfied with half my head cushioned. H and M would customize for $500 but I can't risk that kind of investment sight unsat!
