I started with just providing more leg support with a seat extender and this one worked great however it is a touch too deep for me but if you're a tall person who is likely pushing the seat far back, it may be perfect. https://www.amazon.com/gp/product/B07Y6T2WS3
I notice when you fully get your weight distributed on the seat, then you feel more cush. The way the seat is designed, you kind of are always a little bit forward.
Lumbar support is good, the lumbar feature has an updown and extends quite out on par with the TLX seat so I think you should be fine there. Bolstering it goes pretty dang high to the point where I'm almost touching the ceiling so it has the range.
The one drawback you'll notice immediately is the seat doesn't go that far back which seems odd since there's still a ton of space in the back seat and its not likely people are ferrying passengers all the time. Honestly i just need a few more inches to relax my leg out. Its good the auto stop feature is there to help with that.
The headrest is way too hard compared to the TLX which has more give.
I do feel the way the controls are positioned and that the armrest is a bit low, I find myself collapsing toward the right. That's usually cuz I ride with the seat somewhat higher than typical to see further out for safety (I live in a winter state). But this Fall during all the nice hot dry days I felt safe enough to lower the seat pretty far down down and relax back -- then the arm rest was at the perfect height.
Also compared to TLX the seat feels slightly narrower but that could again be due to the suede keeping you locked into place. So getting a smooth leather and a little movement helps with longer trips.
So long story short, I would pay for TLX seats in the Integra, like they should have a comfort luxury trim for ppl like me who would've basically bought an ILX. But overall for general metro driving and short trips I think its adequate and a step up from Civic econocar. Truly though the nerve of them not to include the up down controls on the passenger side, all my passengers ahve complained they are way too low to the ground.
