If it’s quality furniture you can sell or donate it. If it’s recent Ikea or other cheap stuff, it won’t survive being disassembled, moved and reassembled. Ikea’s surfaces scratch so easily, even on desks. It’s ridiculous. That kind of fast furniture is terribly unsustainable. But I wouldn’t be bothered if you bought a new sofa every ten years and make someone else happy with a used sofa that will last another ten years in it’s new home.
