Created as part of website Pinterest's stand at the marketing festival, the installation is intended to encourage adults to play.
"I wanted to create a play space that gave adults the opportunity to play and tap into their inner child," Ilori told Dezeen. "Sometimes adults forget that its still okay to play. Adults should always make time for play no matter how old they are!"
Ilori covered the playground with prints in his signature style using a range of colours that are being used most often on Pinterest's website.
"Pinterest provided me with some interesting data that allowed me to see what were the most pinned colours used around the world, so I used these colours on my floor design," Ilori explained.
Alongside the see-saw and roundabout the installation includes a series of colourful towers and moveable chairs. Windows cut into the columns reveal information boards containing trends and insights into the habits and likes of Pinterest users.
"Most projects I do always start with Pinterest. Its the best place for inspirations and I always have fun using it."
Pinterest hopes that the playground will encourage people to relax, and take a break from work or using social media.
"Yinka's colourful Playland lets you tap into that open-minded, unselfconscious feeling of childhood," a spokesperson for Pinterest told Dezeen.
"Ride the see-saw, take a spin on the merry-go-round, or just hang out – all without worrying about winning or failing, or getting 'likes'."
"Adults should play more because it frees the mind and brings out a different type of happiness that you can not recreate anywhere elsewhere but only when you play," added Ilori.
London-based Ilori, who specialises in up-cycling vintage furniture, is currently very much in demand.
Earlier this month, his bright The Colour Palace pavilion outside Dulwich Picture Gallery opened as part of the London Festival of Architecture and he designed the Get Up, Stand Up Now exhibition at Somerset House.
