And the announcement of a £1.5 million Air Space park in Wolverhampton means there will be soon be TWO trampoline parks fighting for customers.They will be just five miles away from each other and both have addresses beginning with the name Bentley.Jump Nation has already said it wants to open a site at Bentley Mill Way, Walsall this winter.That’s just down the road from Air Space’s site at the Bentley Bridge Retail Park in Wolverhampton.Air Space currently has the largest indoor trampoline park in Europe at East Kilbride in Scotland, but the Wolverhampton site will be almost half as big again at a whopping 50,000 square feet.That means more than 100 connected trampolines to play on, jumping from one trampoline to the next or taking part in team sports like basketball and football on super-sprung pitches.Air Space is due to open during the winter, creating 80 jobs.The company was launched by the pair behind the award-winning forest adventure Go Ape.
