We recommend oiling depending upon humidity and heat conditions. If the room is hot and dry, more moisture will be lost from the wood and so more oiling will be needed, maybe once per season. If not, then once or twice a year should suffice, usually in spring and autumn. It is important to keep the woods at a consistent humidity levels by protecting them with oil, varnish et cetera because wood expansion and contraction easily breaks joints and can ruin your furniture. Teak oil is especially useful on dense woods like teak, walnut, white oak, and rosewood as it has the ability to seep into their pores better than plane boiled linseed oil.
