Bought a lovesac sactional 15 years ago. Replaced the cushions and cushion covers once. Sides, bases and their covers are original. Best couch ever. Still looks futuristic. Lego Couch.
Nice. We have one for ~5 years now. What's amazing is that it's also so comfortable. My husband or I regularly fall asleep on it and we joke that it's more comfortable than our bed. The only downside was the price (it was the most expensive thing in my entire house for a while).
Oh it's the best! Plus now you can get 3 different firmnesses. When I got new cushions I opted for the middle one instead of the original and now firmest firmness, but they're all super comfy.
It's expensive AF, agreed. When I bought it originally it was a floor display. Imho its worth it though, as it's an impressive looking couch with replaceable parts, and since some parts get wear and some parts don't, modularity is really smart and appropriate for a couch.
As long as the company stays in business, I doubt I'll ever buy another entire couch at once. Hell, rearrange it into a coffin when I'm gone.
