I've been pretty happy with the set I got from Tesmanian for my Model 3, however they're probably the same as some that can be bought cheaper from Amazon, etc. I've used them for 3 years so far without any issues. They fit well and have been easy to take out for winter and put in for the summer.
This set appears to be similar but for the Model Y:
