For full and top grain leathers, occasional treatment with a leather conditioner can help increase their lifespan by keeping them moist and supple. In most climates, this is not strictly necessary but if you live somewhere hot and dry, using a conditioner is a good idea.
You should also keep young children and pets away from leather furniture where possible, especially unprotected full grain leather.
Of course, despite our best intentions, there is always the chance that something could be spilled on your prize leather seat. Rather than waiting until that time occurs, we recommend preparing a stain removal kit based on our ultimate guide to leather stain removal.
