And we have lift-off! Three of the chairs were delivered today and I just managed to get one setup. Pictures below - please excuse the state of the room. Setup there is very much a work in progress
Initial impressions are as follows: The main seat itself is quite comfortable - nicely cushioned with a bit more "sink" to them than the chairs they replaced. Headrest cushioning is roughly the same as the Lex chairs they replaced - that is to say, not very good. However the powered headrest makes all the difference and after a few adjustments it cushions the head adequately. I'm not blown away by the comfort in the neck area, but it's miles better than the other chairs I had with the motorized head rest in the mix. I'll take them for an extended comfort test tonight and report back if my opinion changes.
The motorized elements seem to work smoothly and there's a handy 'full reset' switch in between the headrest and leg rest buttons that gradually returns both to the default position when held. That'll save me some time when I'm wrapping up after using the chairs.
There's actually storage in both arm rests, which is a nice surprise. I thought only one arm rest had the storage bin. The arms themselves have a nice bit of padding on top and seem comfy enough.
I know someone posted about the rocking motion, but they don't seem to rock anymore than the chairs they replaced. There certainly isn't any deliberate rocking or swiveling feature and side to side motion is minimal if you push on them.
That's about all I can think of for now. So far I'm pretty impressed and unless I find a major problem with extended comfort, I'll be keeping these ones. Any other questions let me know and I'll try and get back to you with answers.
