It is never a good idea to have "good" furniture when you have young ones around. The furniture never seems to outlast the children's wear and tear. Chris and I have been given most of our furniture through the years. Not that we could not afford buying our own furniture but because we felt why waste the money when it definitely will not last the kids.
I will tell you this though, when we finally buy furniture when Katie finally gets a little bit older I am starting with new dining room furniture. I absolutely loved the set my mother had. She just recently gave it to one of my sisters up in Ohio before my parents moved to Florida. My mother had this whole dining furniture set complete with 8 chairs, two extra leaves for long dining table and a two piece China Hutch. It was a dark cherry oak and it is gorgeous. Chris and I looking into getting a bed in the immediate future. We have been sleeping on a queen mattress and box spring without any type of frame for almost 4 years now.
We used to have a frame but Chris was goofing around and we are left with just the mattress. When we do finally find one it's going to be a king size because I am tired of getting a sliver of the bed.
