[expand]The tree (frame) provided structural foundation. Early saddles used stuffed leather pads without rigid frames, but development of wooden tree allowed better weight distribution and stability. The tree typically had two wooden arches (front and rear) connected by side bars running along horse’s back, the structure maintaining gap over spine preventing pressure on vertebrae while distributing rider’s weight across horse’s strong back muscles. The tree was usually carved from single piece of wood, occasionally assembled from multiple components bound with rawhide or sinew.
The padding protected horse and rider. Multiple layers of felt, leather stuffed with hair or wool, or occasionally inflated bladders created cushioning layer between rigid tree and horse’s back. The padding needed sufficient thickness to prevent pressure sores during long rides yet remain thin enough not to raise rider excessively high compromising stability. The padding was often removable allowing washing or replacement, with wealthy riders owning multiple pad sets in various thicknesses for different seasons or purposes.
The seat shaped from leather provided rider’s interface. The seat was not flat but contoured—slightly dished to cradle rider’s anatomy, raised at rear preventing sliding backward, sometimes with raised front providing support against forward movement during sudden stops. The seat leather was usually thick, firm material maintaining shape under constant pressure. Some saddles used decorative tooling, stamps, or appliqué work creating artistic seats, but primary function remained providing secure comfortable perch from which warrior could fight.
The stirrups (when invented) revolutionized cavalry capability. The earliest stirrups were simple leather loops allowing rider to brace feet, providing stability but little leverage. Later metal stirrups provided solid platform enabling rider to stand in saddle, delivering full body weight behind lance thrust or sword stroke, maintaining balance during violent combat maneuvers. The stirrup invention was so significant that some historians date beginning of medieval cavalry to stirrup adoption, though mounted warfare obviously predated stirrups by millennia.
The girth secured saddle to horse, passing under belly and attaching to both sides of tree. The leather girth needed to be strong (supporting saddle’s weight plus rider during movement), adjustable (allowing proper tension as horse’s girth varied with breathing and body condition), and non-irritating (preventing galls or rubs during extended use). The multiple strap designs allowed load distribution, emergency redundancy if one strap broke, and adjustment accommodating different horse sizes.
The breast collar and crupper prevented saddle migration. The breast collar attached to saddle front and passed around horse’s chest, preventing saddle sliding backward during uphill travel or sudden stops. The crupper attached to saddle rear and looped under horse’s tail, preventing forward slide during downhill movement or hard acceleration. These secondary attachments were essential for cavalry combat where extreme maneuvers would dislodge inadequately secured saddles.
