My upholsterer have blamed the seat lower bun the entire time why they aren't sitting smooth.
I needed to have them removed and find out why the problems on the material laying on the seat bun.
The problem is: that the gaps are too wide.
Once the seat material is stretched over, the gaps widen out away from each other.
That was what caused so many issues.
Legendary also made no provisions for a wire to pull down the seat buttons.
They'll break off eventually if I left them like that.
I don't know what to do.
The only good news is the seat upper back portion relaxed and looks much better now after a week.
