Nops my dear!
In any car the relatively hard contoured seat is very much supportive and makes back more comfortable as compare to soft seat sitting on which makes lumbar area quenched in bow shape resultantly causing L4/L5 compression....
I had been through this and believe me the kind of Hard Seat Civic or City has is very much soothing for persons having back problem .....
Like Molty Ortho bed Matress which is hard but one feels fresh when wake up daily as compare to soft matress...
