Whats Unmounted and mounted

Ok so this is probaly a stupid question but im a total begginer and I have just started learning everything. I have joined the pony club and am leasing a horse and I need to buy a saddle. I have been looking at them and some say mounted and some say unmounted what does this mean whats the diffrence?

The description says that some of the saddles are mounted and some are unmounted? Not sure! Could you copy/paste the description? Maybe that would give us more to go by....

Saddles that are mounted come with stirrups, girth, stirrup leathers etc and unmounted saddles dont:)
