A saddle tree comprising a back engaging element (3) for engaging and sitting on the back of an animal and a seat forming element (4) resiliently coupled to the back engaging element (3) adjacent the pommel (5) by a pair of resilient mounting members (8). A limit strap (17) is anchored to the back engaging element (3) and is adjustably coupled to the seat forming element (4) by a ratchet mechanism (20). The limit strap (17) terminates in a grippable element (32) which is releasably grippable by the ratchet mechanism (20). By urging the grippable element (32) in the direction of the arrow A through the ratchet mechanism (20), the limit of upward travel of the seat forming element (4) relative to the back engaging element (3) is reduced, thereby effectively hardening the saddle.
