"Adopting the position!" Easy up to (whatever) degrees - I've set it up for me and my gas lift chair. Gas lift fully up - I'm looking a bit above the horizon. Smaller people - sit on a cushion! Taller people - not sure?
Drop the gas lift as I go up in altitude, tilt head and, eventually, lean back. The second shot was a quick one for the camera before it rainned (the grass shows we need it) so I hadn't adjusted the bins properly on the central mounting bar for that altitude.
(ps - book appointment with chiropractor for day after viewing at altitude.
)
More details and "road test" next post.
