I'm 6'1" (so not quite 6'5" admittedly!) and I recently purchased a Herman Miller Sayl chair and I love it. I got mine without the arms as I have a strong dislike of desk chairs with arms.

Large size Herman Miller Aeron.

Just having mine repaired with a couple of parts - purchased in 1997 or thereabouts. Expensive but worth it.

warehouse stationery. if on special they're cheap and mostly good (the only issue is the arm rest padding is deficient in most chairs but the rest are all and big)

6'5!! healthy diet of weetbix as a kid I see!

Where are you based? Office Max have a decent range of proper office / desk chairs that you can sit on and try out to help make up your mind 

if you're after a decent chair, I personally wouldn't recommend buying a chair from warehouse stationary, for what they are they're over priced even when on special 

i suspect @toejam316 is an expert in this department...

Based in Hamilton, I dont think most of office max would have chairs that would last 5-8 hour work sessions or have support for my frame anyway.

unisonworkspaces or ergostyle have alot of chairs but they don't have much reviews online, so im not sure about them. 

The Aeron is tempting but its quite far out of my price range.

Oddly I just got a new one a month ago.

Most comfortable chair I've had, I'm 6'4" and the head rest is usable, rather than just making me lean my head forwards to be uncomfortable. Can't recommend it enough, great chair.

Are you using the lumbar support part? any good?

Yep, nothing but positive things go say about that chair. It's excellent. For reference I had a DX Racer King series before that, which suffered a mechanical failure and is off being investigated by the nz supplier at the moment.
The Vertagear is leaps and bounds better, and is one of the more comfortable chairs I've had. I suspect I could sleep in it.

Think I know what to ask my wife for Christmas now :) 

I'm 6'2 and a fat bastard, when I wanted to get myself a decent chair a few years ago I ended up with one of these:

https://knightgroup.co.nz/plymouth-task-chair-kg-plymouth.html

Rated for 10+ hours use for up to 160kg, with a 15 year warranty. There's also a heavy duty version with a metal base rated for 200kg.

My 160kg version with arms cost me $621 just over 2 years ago.
