I think I'd turn the tips of the skis away from my back, giving the chair a nicely curved back that wouldn't stick me in the neck with the tip of a ski.
And for the saet, I'd lay the seat boards in line with the direction my legs went, not at right angles to my legs, Again I'd use the front ends of the skis, but this time with the tips pointed down, so my legs could comfortably hang over the graceful curve they made.
The downside to pointing the tips away from the seated perso is that they end up sitting on the not-so-decoratvie bottom of the ski, rather than on the decorated top.
Just a thought
Are those skis so bad that they can't be repaired or used by some poorer skiers?
