For a bed to function properly as a spawn point it must be in a valid room though other than the bed itself no other furniture or lighting is required. A bed may be placed in a non-rectangular room as long as the leftmost 3 blocks immediately above it are left clear. For instance, there may be a bed (4×2) surrounded by walls on the left, right and bottom sides, and above the foot of the bed. So long as there is space for the player to spawn at the bed the bed can be set as a spawn point. Such as this image.
