Joel Corry, Raye and the French dance-music producer David Guetta are all credited as the principal artists. Corry explained to Official Charts Company
the track originated as an idea that Raye and Guetta came up with.
Later, during a summer 2020 studio session with frequent Jess Glynne collaborator Janée "Jin Jin" Bennett, Corry was listening to demos recorded by Raye. After hearing "BED," he was drawn to it and contacted Guetta, who was happy for him to work on the tune with Raye. The pair hit the studio together and developed the rest of the song.
The three announced the release of the single on February 26, 2021, with each artist posting a picture of them lying in bed.
