I ahve the exact same seats fitted into my Elite (they came as a standard option from new) and when I first bought the car I almost decided to get rid of them and revert to the standard leather .Your description of sitting on them as opposed to in them is spot-on.It took me about 2/3 months to convince myself they were okay ..now I find them great and very comfy..slight downside is they get very/very hot in the summer as the colour soaks up the heat,and very very very cold in the winter.My passenger side heater works but takes a while to warm up..drivers side doesn,t but I have a new seat pad to get fitted when I can afford the cost of the upholsterer stripping the whole lot down and re-stitching the leather back after..was quoted £140=00 before Christmas but still saving up.
Just for my info do both yours heat up? and if so are they fairly quick or slow like my passenger side.Andrew
