Our customer Reviews

Cynthia London
Bounce4joy gave us an impeccable service! They were not only on time, but early to arrive! The bounce4joy staff also even helped us with our own unloading/heavy lifting as we were struggling. Bounce4joy then surprised us with an all action dancing/acting and web shooting spiderman for an hour!
Gloria , Luton
The children loved it and even the adults enjoyed it. Our speaker was very small and a bit useless but bounce4joy even offered us their speaker for use at no extra charge AND supplied music and sound effects for our games with no fuss and without even being asked
John, Hatfield
Overall, they gave us a fantastic service, experience and most importantly created happy memories for the families that attended the event! Will definitely be using them again and have even booked them for a private function in the next few weeks!
