They will raise you up about 3/4". Very much worth it though.
My only problem with the Underground Autostyling mats is the huge logo on them.
The added height might help... Only 5'9. But I've never felt I needed to slide forward or backward. They're pretty much all the way back. Passengers don't complain either since the space is shallower on that side with the flat muffler wall.
When my mother in law tried to drive it, she did have to sit scooted up and with a pillow behind her since it didn't slide so she could reach the pedals. Not my problem though. 😁
And underground makes them without logo for a bit more of cost.
