Protesting parents and their children made a noise over the state of their playground.
Families in Mile Oak say youngsters believe there is a lack of facilities at the park in Chalkey Road.
And they are collecting signatures for a petition they hope will encourage Brighton and Hove City Council to make amendments.
Mile Oak resident Ian Downes said: “It was renovated in 2010 and it was quite unsafe. The park before was really good but now it is in a bad state. There is nothing for disabled or younger children to use and there’s no slide for bigger children, only under-twos.
“I was told the council spent about £70,000 renovating it but I can’t believe that.”
Tiffany Soanes, 39, of Graham Avenue, said around 1,200 children went to school or lived in the area and had access to the park – but some of its facilities were unsafe.
She said: “There are a few issues with safety, for example there are mounds everywhere which makes it difficult for youngsters to move around and the roundabout is raised.
“There is also a lot of empty space compared to other parks that have been renovated. It doesn’t cater for children of all ages.”
