The most expensive piece of furniture I own is a set of 2 chairs, a couch, and an ottoman that were originally found on the side of the road in Fort Belvoir VA sometime in the 50s (ish). They're the most expensive since they had to be recovered (in this gorgeous blue damask patterned velvety fabric that cost a pretty penny). (However, the folks paid for that since it was heirloom furniture.)
Most expensive that I bought is an antique vanity with a triple mirror at an antique shop that I never had been to before for $200. It only needed to have new knobs put on and it matched the rest of my hand-me-down furniture perfectly.
The most expensive thing I own is my bunny himself, with all his vet bills (not even counting his food or all the headphones he's destroyed).
Our furniture is all pretty cheap (ikea, thrift, street, west elm).
I like my "things" but they are mostly replaceable and I really don't care about most of the furniture and electronics and high ticket item stuff.
If my apt burned down and my clothes and bunny were safe, I would be fine.
So I guess I would trade my wardrobe for the rest of the house put together.
I really like my furnishings. I call my decorating scheme "early american attic" since it's all handmedowns except for the wicker chairs.
I have items from the 40's that were my grandparent's in Panama when they had nothing but a trunk of personal belongings and bought locally made mahogany table and chairs, to 60's blond wood coffee table, to 70's celadon green 20's inspired sofa.
It all has history and blends together with the few modern pieces I've scavenged, and my paintings, to create a compelling tableau.
Most of our furniture are either family hand-me-downs or Craig's List finds. It's almost all 19th Century but none in good enough shape to really be worth much. A few pieces, like the desk I'm typing this on go back at least four generations.
I don't think any of my furniture would count as expensive. I have 100+ yr old chest of drawers that was 350 euro at an auction. And I bought an Italian design dinner table from Chinese expats in The Hague who were moving back. I think that my saxophone is the most expensive object in my house.
My most expensive piece of furniture is my dining room table - French-polished, veneered yew, it sits neatly in the corner but will expand to seat 8.
The next most expensive is my sofa. It took me ages to find a sofa to fit me - I'm so short that most of them were too deep to sit comfortably. But I also wanted one that was big enough for me to lie down on. I got it from a furniture store I always thought would be too expensive, but it turned out to be as keenly-priced as the big chains when it had its sale. Lucy and I love our sofa naps.
I have no idea what our most expensive furniture is. I love my bedroom furniture, almost all of which has been gifted to me by the Bear over the years, but he is a very careful shopper. I most value our dining room table, which he made many years ago. A heck of a lot of our furniture would be of interest only to people who enjoy cat scratches and dog hair.
