The deal marks a vote of confidence in the leisure sector post-Covid, and will be welcomed by landlords at a time when a number of retailers are looking to close shops due to tough high street conditions.
It emerged last month that Debenhams would start winding down its 124 shops after no rescue deal was agreed for the struggling chain.
Harvey Jenkinson, chief executive of Gravity, which started as a trampoline park operator in 2014, said: “We believe that concepts like this will be the future of the high-street with retailers closing, offering a solution to landlords who are concerned about how to fill the space and attracting more footfall to shopping centres.”
The shopping centre is co-owned by Landsec and Invesco Real Estate.
David Heaford, managing director, development at Landsec, said: “Leisure is an increasingly important component of a complete destination, and Gravity is a significant addition that complements Southside’s existing offer."
