I would suggest a product called saddle soap. I used it on all my leather furniture. It can be found at farm supply stores, such as Farm & Fleet (Fleet Farm, depending on where you live), or at any feed or tack stores. It cleans and conditions the leather. I hear it is also good for leather car interiors, leather jackets and that sort of thing. It cleans the leather while keeping it soft. Most cleaners will strip the oils from the leather, making it brittle.
