Reid, who presided over Flint’s funeral in 2019, insisted people were “amazed” by the bench “and what it means to have it here”.
More than 5,000 people attended the funeral after Flint was found dead at his home in North End in March 2019.
Band manager John Fairs and Prodigy founder Liam Howlett helped to design the tribute, later signed off by Flint’s family.
“For local people here in Braintree and around, this means an awful lot,” Reid said.
“They remember seeing [Flint and Howlett] on the dance floors in Braintree. They have followed them all the way through and they are proud.”
The design of the seat was praised by many people commenting on the band’s Facebook post, external about it.
Flint already had a tribute in Braintree, where a mural of him was spray-painted on to a water tank at Braintree Town Football Club’s ground.
The Prodigy – who also include Liam Howlett and Keith Palmer (known as Maxim) – are staging a world tour in 2026.
