i am 1.83m. i find the material of the seat very good, but just somehow find that the lower back is not properly supported. In fact the seat cushion is more protuding out at the higher back position and the lower back portion is concave inwards, leaving a gap between my lower back and the seat cushion, thus not been supported and thus to be uncomfortable.
Sunny, starlet, altis and GE fit's seat all din have this issue lei. Or is there a level to push the lower back support out? Cos i notice altis got this type of feature.
