Not the chair thread, but I got it in. Heavy as absolute fuck, but went together easy and my back feels so much better. Plus I can recline it all the way if I want to sleep. 10/10. Got the PU leather instead of fabric. Not sure if that's a mistake, but I've been in a cloth chair for 15 years and I hate it. You read that right. I've had this chair for 15 years.
Assembly took about 30 minutes, they included every tool I needed, and everything lined up perfectly. I went with the Titan because I'm 6'3" and my head just barely peaks over the top of it. Memory foam pillow is actually very nice.
