We want to buy a sofa

Our house has just finished decoration. It is time for us to buy all kinds of furnitures and home appliances. We have reached an agreement on what kind of home appliances and dinner table we should buy. But it is very hard for us to reach an agreement on which kind of sofa we should buy. My girlfriend like leather sofa as she thinks it is more comfortable to sit on. I like fabric sofa because it warm in winter, and it is very comfortable to sleep on. But my GF’s parents prefer Chinese style wooden sofa, they argue that it is more strong and durable. But both my GF and me don’t like wooden sofa, because it is very hard, not comfortable to sit on. It is also outdated.
According to the tips from internet, inexpensive sofa can break and will look out of shape within a year of constant use. After visiting all the furniture stores in Guilin, we decide to buy a Kuka leather sofa, for Kuka has the reputation as the leading brand of leather sofa. They have a promotion recently and we can get a good deal on one model.
