Safety: Merbau has been associated with mild allergic reactions: most common is skin irritation and a runny nose. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Price Range: Sold infrequently in the United States, Merbau is  a large tree and is somewhat moderately priced for an import, and should compare closely to Mahogany.

Comments: This wood has excellent strength characteristics, along with excellent stability, making it ideally suited for use as wood flooring and other applications where strength is important. It is commonly used for furniture and other specialty wood items in southeast Asia where this wood grows naturally.
