People keep asking this over and over.
The answer is YES, it’s easy to keep clean. Many people have said they had messy kids and still had no trouble, still looks new after a year. Other people on Youtube are pouring red wine onto their white seats.

The main tips are to have some wet wipes nearby and also magic eraser. If you love the white look, get it!
