How long did you let it unroll? It needs a bit of time in a warm room. Might take a day or two for it to completely unroll into the relaxed state. Might consider kinda "helping" it along by putting a bit of weight onto the opposite direction of the "bend" to get flat (think like you're unrolling a poster).Hello there xerostatus,
I have bought the smartliners set on amazon, they fit perfectly except the trunk doesn't look as good as yours, since it came wrapped in a large tube box and it is more tilted on the right side. I wonder what you had to do in order to get it to fit perfectly in your trunk?
