If by "horse chairs" you mean the contraption that sits on their back, the correct term is saddle. The "foot things" are called stirrups, and the stirrups are used to balance mostly, although you should be able to balance without them. They are also used in English riding to stand up in the saddle to post or to jump.

Horses can get an abcess in the feet at any time of year. It is a good idea to check your horses feet and clean them every day to avoid foot problems.
