Four years ago, Apartment Therapy ran a Sleeper Sofa competition. (Evidently, four years ago the switch from “sofabeds” to “sleeper sofas” had already happened.)
Apartment Therapy put together a shortlist with 15 sofas on it. I found it quite quickly, when I started looking for a sofabed myself. And how many of the links to those 15 sofas are now broken? All of them. People, I’m all in favor of keeping websites fresh. But don’t break all your old links when you do so.
That’s why you need archive.org
After four years, I’d suspect many of the beds are also broken.
