What Our Customers Are Saying
This was a game changer for my son's 1st birthday with a ton of toddlers running around! This company was amazing from start to finish and I will be using them again in the future. If you are hesitant to book, just do it! The best money spent for a party with a ton of kids
We had a fantastic experience with Party Baby: We used them for our two year olds birthday party. The process was smooth and the set up was gorgeous. The littles had a blast. I couldn’t have asked for more. 100% recommend.
Wonderful job! Our celebration for our grandson's first birthday was hugely successful due in part to Party Baby Soft Play. All the kids enjoyed it as well as their parents! Thank you for everything!
Best idea ever to have Party Baby Seattle come setup a soft play area for the little ones celebrating in this birthday. There's too many things that one as parents try to figure out and this was one less thing I had to worry about. There was a place where they had so much fun together and it was safe and beautiful. The team was super sharp and on time, very swiftly setup and gave us recommendations of where to put it. Then just as swiftly as they setup they also came after the rental time expired and also left the area just as they found it.
The team is super professional and I would gladly do business with them again, everyone that came to the party was left in awe and wanted something like this for their future party. You don't even need to spend a lot on decorations the setup itself was decoration enough.

My company has worked with Party Baby two years in a row now to have a bounce house at our client's company holiday party! Not only are they extremely professional and organized, they also are always upgrading their packages and providing amazing options. The kids love it, and the attendants are always making sure everyone is safe.
Everything was fantastic! The kids absolutely loved the soft play area and didn’t want to come out. The setup was perfect, clean, and exactly as advertised.

The variety of activities kept all the kids entertained and engaged throughout. It was truly the best decision to hire them for my son’s birthday party! Highly recommend for anyone looking to add something special to their event!
