Good morning Sophia, I wrote to you last night in the forum, but either my post magically disappeared or I didn't save it correctly ( probably the latter lol!). I wanted to tell you that when I was test-driving Prii that didn't have lumbar support, my back did feel strained and uncomfortable, so I experimented with the position of the steering wheel...I pulled it down to its lowest position, and that changed my arm and back positions just enough to get rid of the discomfort. Maybe you could try it out and see if it becomes more comfy for your back. Have a sweet day! ~ Val
