Bought for Clio III More so effective back pain but I'm not about positioning to adopt According to the scheme do not put it all down but in this case, given the thickness, it bothers to drive So I put down a liaison with the seat On the other hand the elastic to tie the chair is too short which tends cushion and prevents him from marrying the chair and the driver therefore is useless
Update 29 May 2015: I confirm after 4 months of use I have no more pain in the lower back. The pad does not leave my seat. Note that I am doing 3 to 4 hours drive daily. So it is a priori a good product that compensates car seats not comfortable enough for long trips :)
