In the title compound, C17H19NO3S2, the maximum deviation of atoms in the 2H-chromene ring system is 0.0097 (14) Å and the piperidine ring adopts a chair conformation. The dihedral angle between the 2H-chromene ring and the piperidine ring (all atoms) is 87.59 (8)°. In the crystal, inversion dimers linked by pairs of C—H...O interactions generate R22(22) loops. Further C—H...O hydrogen bonds link the dimers into [110] chains and weak aromatic π–π stacking [shortest centroid–centroid distance = 3.824 (8) Å] is also observed.
