Nursing Room Description Safeco Field in Seattle has a nice mothers lounge (nursing room) on the Main Level in section 128 Near Guest Services.
Also baby-changing tables are located in most restrooms throughout the ballpark.

I walked in there and never saw so many boobs. Great to know I wasn't the only breastfeeding mom in the park and that they created a space for it."
