Mahogany (I think). I’m not very good on woods, but the top and legs look like mahogany, although the lower tier looks almost like Rosewood.... Top surface is octagonal, with mouldings round the sides; the lower tier is a sort of square, with serpentine sides. 4 turned legs, with brass and brown ceramic castors - see second photo. Overall dimensions (cm) approximately: - Height: 73 high. - Top: 83 across. - Lower tier: 49.
