I know exactly what you mean.  When my parents left the home that I'd been a teenager in, going to their new home after that was never quite the same.  It's silly when you think about it, because they were the same people, it just wasn't the same house.  But having a few things in my own home that remind me of 'home' helps.  You have a seder table, I have an old fashioned wash stand that I treasure.
