The present invention describes a platform assembly having a centre clamp (2) formed from at least two clamp segments (25), a platform (1) formed from multiple platform segments (15) fixed together and a plurality of brackets (6) mounted into the centre clamp (2) at one end and supporting the platform (1) at the other end. The centre clamp (2) is formed from at least two clamp segments (25), which are joined together around a post or trunk (70) and once joined together, the hole in the centre of the clamp (2) has clearance around the post or trunk (70), so that the clamp (2) can be used on multiple diameters. The clamp (2) includes adjustment means (5, U, L) that can be operated to adjust the pitch and roll of the platform (1, 50) to achieve its horizontal position before the clamp (2) is secured to the trunk or post (70) to fix this position.
