The soft play equipment will be used during the Colchester Tots sessions, which are designed for children aged five and under.
The sessions run every Tuesday and Thursday from 9am to 11am and cost £5.70 per child.
The new equipment replaces older features and aims to provide a safe and stimulating environment for children to learn and play.
Councillor Martin Goss, portfolio holder for waste, neighbourhoods, and leisure at Colchester City Council, said: “We’re thrilled to bring in this new play equipment to enhance our Colchester Tots sessions.
“These mornings are all about giving local families a safe, welcoming space where little ones can learn, grow, and have fun together.
“It’s not just soft play – it’s a community hub for parents and children alike.”
Parents can also enjoy a 50% discount on drinks at Paddy & Scott’s coffee shop during the sessions.
