I've never been particularly fond of leather furniture. To me, it just doesn't scream, "warm" or "cozy"... which take precedence in a living room in my opinion. However, these living spaces which effortlessly mix and match upholstery with leather are putting this combination into a whole new light...
the clean lines of the leather pieces really do give a certain chicness to these rooms
they also provide texture which is a great way to create a well rounded visual space
and in this particular space... your getting the best of many worlds - leather, tufting, and upholstery.
