Every single IKEA piece of furniture in my house (desks, tables, sofas, shelves...) is entirely "lossless assembly", although when moving I didn't have to put them apart down to individual parts because they're also designed for whole components to be (dis)assembled and reassembled quickly. I think I have like one piece of furniture that is not entirely lossless and that's the back panel on a closet that needs to be nailed (which provides diagonal constraint), which I've done three times over yet still has room for more. Okay it's not grandma's stuff that's made of thick solid wood and lasts centuries, but it has really held up well to reasonable abuse.
