Combining the Old with the New

When I moved from Honolulu to Portland, I brought only a few pieces of furniture with me. The heaviest and biggest pain in the tukus is a teak credenza that I bought from Bali Boo in Kailua in 2005. Even though I love it and its a convenient place to store everything from bed linens to office supplies, I've wanted to get ride of it multiple times. It was usually the one piece of furniture that required a flatboard truck and more than one person to move. But I still have it and its now survived 6 moves. In my current home "office", I use it as my standing desk. Combined with more current purchases, I think it keeps the space from looking right out of a West Elm catalog. What furniture have you held onto that plays well with newer pieces?
