The timber used to build this product has been pressure treated for durability and longevity and is likely to still have some green spotting on it as a result. There is no need to worry about these small dots as they are perfectly normal and will disappear within just a few weeks. Wood is a natural material and will inevitably move and warp slightly with time. If your wood splits or cracks with the passing seasons there is no need for concern, this is a natural by-product of timber construction. Please Note: You cannot return this item due to green spotting, as this is a result of the product being treated, and it will fade over time.
