The nearside rear cushion and squab are Latex, whilst the offside have spring frames. We would welcome your opinions of these two types of seat. Our impression is that whilst the spring cushion type may appear to be more soft and comfortable when the car is stationary, the Latex type is better on the road due to two features:- (1) the Latex has an increased rating as it becomes compressed, whilst the rating of the spring cushion is constant. (2) the Latex has natural damping whilst the spring frame has very little. EV.{Ivan Evernden - coachwork} | ||
