Charlie,

Excuse me if I am telling you something you already knowR= 30; but my experience is that a thinner seat BACK had a much great impact on= the knee-to-panel clearance. My initial experiments with seat bottom = cushion were disappoint, and then one day I modified the seat back cushion a= nd my situation was greatly improved.
