Sundance 4717, Angelo chair & ottoman 2010, 2009 in a dark leather like Antelope Nugget. Can we back track a bit, though to the leather selection? Our house is passive solar, which means that for a few months during the winter there will be sun hitting the front of the furniture. We will not put a sun barrier on the windows as that would defeat the purpose of passive solar. Given that, is a protected leather going to be a better choice or can we just as easily protect any leather with a sun block treatment? Or is it even safer to use a sunblock with a protected leather? This advice will help me with my leather choice!
