Trying to find an ergonomic mesh frame that actually stays comfortable late night

My current chair is completely worn down and giving me zero posture support during long evening sessions. I want something breathable that will actually help me sit comfortably for hours without feeling stiff by midnight.

I was looking into adaptive lumbar frames and the Hbada X7 caught my attention while researching ergonomic options, but I have a few practical questions before pulling the trigger:

• Reclined controller play: Does that floating lower lumbar piece feel comfortable when you kick back with a controller, or does it push too hard against the spine
• Seat pan comfort: Does the mesh seat base stay supportive after 4 to 5 hours of continuous use without feeling harsh on the thighs
• Armrest clearance: Do the armrests adjust smoothly so you can slide them low enough under a standard desk height

If anyone is daily driving this model for long gaming or desk sessions, how has the day-to-day comfort been holding up?
