Here for you since 2011!

Thanks for visiting!

Our indoor inflatable playground opened on October 10, 2011. We have been voted #1 "Favorite place take kids" by Sauk Valley News readers poll every year since then. THANK YOU Sauk Valley!

We are excited to bring you a fun place to play and party in the Sauk Valley Area no matter what the weather is like outdoors! Avoid the heat and bugs in summer and the cold, wet days year 'round at our place!

We are located at 505 W. Lynn Blvd, Sterling, on the southwest corner of Lynn Blvd and YMCA way- one block west of Locust St. Just a hop, skip and a jump from you- no more drives and gas station fill-ups to find something fun for the kids to do!!

It's so much fun that kids don't know it's exercise - parents and grandparents LOVE to wear the kids out here before taking them home for some quiet time... maybe even an EARLY bedtime!

Fun jump is family owned by a couple who care about our community and our families living here. We have children... and grandchildren! We are focused on providing a safe, clean and fun environment for kids to enjoy physical activity no matter what the weather brings.

Kids at Fun Jump have so much fun climbing, bouncing and sliding that they don't even know it's exercise!

With reports of childhood obesity increasing in our country and kids becoming more sedentary, we hope YOU will join us at Fun Jump to encourage kids to "play an hour a day"!

8,140 square Feet of FUN!!!

We have 2 Party rooms and 6 giant inflatables including slides, bouncers, obstacles and an adorable farm village especially for kids under 4 years.

All units are cleaned and disinfected daily! We take pride in our image and love your comments on how clean everything is.

Keeping Fun Jump clean and safe are two BIG priorities!!

Walk-in play anytime we are open- no reservations needed!!

We have Xfinity on large Flat Panel Televisions- one for the kids and one for the parents!

We DO NOT allow any outside food.

Please support our small business by purchasing snacks on site.

Concessions are available featuring Pepsi products, shaved ice and slushies along with an assortment of popular snacks, including pizza, all beef hot dogs, jumbo soft pretzel with cheese dip, Macaroni-n-cheese cups, ice cream cups and other packaged treats. NEWER items on our menu include Cheese burgers and Chicken Sandwiches.


Adults are asked to monitor their children and must stay on-site with them while playing. Our trained staff is here to supervise and ensure that safety rules are followed while allowing their parents and caregivers time to relax and look on.

We clean and sanitize all our inflatables and eating areas to minimize transmission of the usual "kid germs".

Your hand washing or use of sanitizer upon arriving to play (and also when leaving) is the BEST way to help keep kids (and grownups) from sharing their bugs with others.

Our staff and fellow customers appreciate your efforts to keep sick children at home!

Fun Jump is especially for kids ages 12 and under accompanied by a parent or guardian.

For safety reasons we do not allow adults to bounce with the children, but they may assist children under age 4 years and are allowed to sit on the inflatable structures and enter if your child needs encouragement and companionship.

  • parties
