Bench to Bucket Conversion Advice

Ok keep me in mind, what color and condition is the vinyl in? Part of the appeal of the original posters was it matches the pearl white. Ha I'm probably weird for wanting to go from buckets to bench.
My bench is pearl white with the arm rest.
It is not original, at some point it has been recovered.
It is in very good shape other than a weird yellowish mark under the arm rest?
