A recyclable polyurethane foam is produced by reacting a disulfide reactive chemical-based polyol-containing composition and an isocyanate composition. The polyurethane foam may include a molar ratio of the disulfide reactive chemical of greater than or equal to about 2:1 mol %, 4:1 mol %, or 6:1 mol %, wherein the ratio equates to the molar ratio of hydroxyl groups of the disulfide reactive chemical versus the molar ratio of hydroxyl groups of the polyol.
