Our club is nestled in the heart of Wandsworth and offers an abundance of state-of-the-art apparatus that will have the children leaping, jumping and tumbling with joy. The partygoers can enjoy a variety of gymnastics and ninja activities on our quality equipment, which include a giant air track, sprung floors, beams, bars, a ninja obstacle course, and much more!

Whether you’re a member or non-member, all children are welcome to host their birthday parties at Gymfinity Kids. We want all children to have the most memorable day ever! You can choose the party theme from a choice of a Gymnastics theme, Ninja theme or Fun-Time which is a mixture of both activities.

You can view the gym floor from the seating area so can watch the kids playing games and exploring the equipment. There will always be coaches on the gym floor to supervise.

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.

What food can I bring for the party?

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.

Please note, that our clubs are NOT allergy-free facilities. We recommend that you do not bring anything that contains nuts on-site and check with the parents/guardians of the children you have invited regarding allergies.

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