A coffin is constructed to hold an inner coffin for holding the mortal remains therein or thereon. The inner coffin has a bottom, opposing first and second ends and opposing first and second sides extending in a longitudinal direction of the inner coffin between the first and second ends. The coffin comprises a base for supporting the inner coffin; and a cover to provide at least partial covering of the inner coffin when arranged on the base. The coffin allows displacement of the inner coffin over the base by allowing passage of the inner coffin from the base at one end or side. The coffin further allows access to at least one other one of the ends and sides of the inner coffin from lateral directions along a support plane comprising the bottom of the inner coffin for getting hold on the inner coffin to move it along the support plane over the base in the direction of the one of the ends and sides of the inner coffin.
