The filmmakers cited Girish Karnad's Kannada play Hayavadana as a significant creative influence.

Srijit Mukherji first announced the project in early 2020 under a working title, Tritiyo Jon (The Third Person). He cited the French film Jules and Jim and Ingmar Bergman’s Persona as tonal inspirations, but emphasized that 3 on a Bed was rooted in the "emotional dishonesty of the Bengali upper middle class." The title was finalized in October 2020 as a deliberate provocation, referencing both the physical intimacy and the claustrophobia of non-monogamous arrangements.

The soundtrack mixes acoustic ballads with soft indie-pop numbers, reflecting the contrasting personalities of the leads. A standout song performed by Sameer’s character becomes an emotional anchor in the film, used to highlight moments of vulnerability and reconciliation.

The story begins with Raj (played by Ankush Hazra), a struggling artist who lives with his two friends, Aryan (played by Rajat Mukherjee) and Sanjay (played by Aytik Das). The three friends are inseparable, and their friendship is put to the test when they decide to share a flat in a prime location in Kolkata. As they navigate their lives, they face a series of comedic misadventures, especially when it comes to women.
