Our gymnastics and ninja club is stocked full of specialist equipment which will provide endless fun for the children. The kids can try various gymnastics and ninja activities and games on our state-of-the-art equipment, which include a giant air track, spring floors, trampoline, beams, bars, ninja obstacle course, and much more!   

What to expect at our Chatham birthday venue 

Members and non-members are welcome to party at our club – we want all children to get the chance to have an amazing birthday! We have three party themes on offer for the birthday child: gymnastics, ninja or fun-time (a mixture of both activities).  

Our parties take place on Saturdays and Sundays, and we can host parties for up to 15 children. More are welcome to join – an extra 5 children can be added to your party booking for a fee. 

During the party, the children will get an hour on the gym floor having fun and games, and a 30-minute break for food and present-opening in our funky Chatham birthday party room or café area.

You can head to the viewing area where there is plenty of seating to view the gym floor and can watch the kids playing games and exploring the equipment. There will always be coaches on the gym floor to supervise.

What food can you bring?

You can bring whatever food you wish for the party! You can bring in cold food such as sandwiches, crisps, chocolates and other snacks. Feel free to nip out and collect your feast while the kids are partying on the gym floor, however, there needs to be at least one parent on site during the party.

You can also order pizza or other hot food to the club if you wish – please be aware of the timing of your booking though. If you order food to the club, it must arrive on time as we cannot extend your party booking slot to accommodate late arrivals of deliveries.

Some of our clubs offer food packages, however this is yet to be rolled out to all clubs due to availability of facilities. Please enquire with the club at or Member Services at regarding food packages for parties.

Are there any age restrictions for the birthday parties?

Children under 5 years old are welcome to join in the fun at our birthday parties, however, they will require a parent or suitable adult to accompany them on the gym floor. Please let us know if the majority of your guests will be under 5.

Can we decorate the party area?

We highly recommend for you to bring decorations to decorate the party room or party area whilst the children are on the gym floor! It can help make the day feel extra special for the children and add that extra sparkle to the experience. You’re more than welcome to bring table clothes, streamers, bunting, birthday balloons and other decorations.

We’ve even had parents bring Snow White along to help sing Happy Birthday! Please speak to our Member Service team or to the club reception about your plans if they go beyond decorations. We’ll see if we can accommodate any extra touches you wish to bring to the party!

Please be aware that sometimes we have many parties booked so we can only let you decorate once your party slot has begun, and please factor in time after the party to quickly tidy up what you’ve brought.

Can parents bring alcohol into the club?

No – we do not allow any alcohol into our clubs and alcoholic beverages are not to be consumed on-site.

In the instance of a party booking, a minimum of 50% of the party cost will be taken at the point of booking. The final payment must be made a minimum of 2-weeks before the party date. Failure to do so will result in the party being cancelled.

You will be entitled to a full refund should you cancel more than one month before the party date, and there will be a 50% refund if your party booking is cancelled 2 weeks before. You can reschedule the party free of charge for another date if less than 2 weeks prior. In this instance you will not receive a refund.

Can we extend the duration of the party if needed?

Unfortunately, we’re unable to extend the parties beyond 1.5 hours due to classes on the gym floor and other party bookings that will require the gym floor and party area. We will need to keep to the timings so please be sure to arrive on time at the start of your booking so you don’t miss out on any fun!

Do I need the parents of the attending children to sign a waiver?

Yes, we will send you the waiver to circulate to the parents of the children you have invited to the party. This needs to be completed before the party.

The waiver ensures we have the details of the attending children, including their GP practice, medical/behavioural conditions or allergies, consent for Gymfinity Kids social media and an emergency contact.
