In the title compound, C(17)H(20)O(3)S, the cyclo-hexyl ring adopts a chair conformation. In the crystal, the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further stabilized by weak inter-molecular C-H⋯O hydrogen bonds. In addition, the crystal structure also exhibits aromatic π-π inter-actions between the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.505 (2) Å, inter-planar distance = 3.385 (2) Å and slippage = 0.909 (2) Å], and inter-molecular C-H⋯π inter-actions.
