Basically a variation off the full recliner, with only the back tilting mechanism. In theory this design allows for a more comfortable seat, in B&Y 8 way tied spring seat, also that this mechanism and overall structure will last much longer. Just about all other recliners and motion upholstery, not only does the seat / back / foot rest all move together, they also have to support your full body weight. In time the joints will wear and become loose, making the mechanism more difficult to operate.
The down side is that a ottoman is almost always required, as most people find it uncomfortable without a foot rest in the full recline. Depending on the space available, the floor type (as you will need to move the ottoman around) and when sitting in/out of the chair the ottoman can be in the way.
Their are several variations of control, the retailer should be able to provide the details, just consider the lower back versions have no headrest.
