The finish on wood outdoor furniture, when exposed to an environment with substantial temperature changes (moisture, sun, and salt air) can change over time. It is not uncommon and users should expect some swelling, discoloration, or possible surface cracks due to the outside exposure and changes in the weather. These are considered natural occurrences of wood and should not be considered as a product defect. To prolong the life of your item you should consider placing it under a covered area.
