A person or horse that ambles; something that moves at a slow, steady, comfortable pace.
From amble + -er suffix (one who does). Originally referred to horses trained to amble, a smooth gait preferred for comfortable long-distance riding.
Medieval nobles preferred 'amblers' to trotting horses because the ambling gait was incredibly smooth and comfortable for long journeys—it's why you see so many Renaissance paintings of nobles on ambling horses rather than galloping ones.
