The bottom of sink rack arrived and was of the quality one would expect from Kohler. I did have to reverse flex/bend ever so slightly for all (6) posts to contact bottom of sink at same time and not rock. This rack is definitely an upgrade to a flat bottom sink, to elevate items being washed or rinsed off, up off the bottom and away from debris, allowing clear path to drain/disposal.

This rack is just the right size for my sink and keeps the sink from getting scratched.

Fits my newly remodelled sink, nice quality.

Love it!!! I looks and fits beautiful in my cast-iron sink.
