Hmmm.........leather shouldn't get sticky if you regularly condition it. It gets like that when the leather ruins in the sun.

We have leather sofas.....which used to be in our living room in the old house, but are now in the family room, so they are used more these days. I personally love them. We keep the blinds in a direction where the sun won't *directly* hit the couches, and we condition them regularly. They're about 5 years old and still look brand new. They do get cold in the winter but never sticky. In the summer, they WOULD get hot, but with us having the A/C on whenever its hot, that just doesn't happen. Our birds are too small to harm the sofas in any way. They sit on them all the time and have never scratched them at all.

We have leather in our cars too and they never got sticky either.
