We brought this home and set it up immediately, and honestly we were worried about getting it up to our second story master by ourselves, but it was well balanced and not terribly heavy for what feels like a dense mattress. Testing the bed out, we fell promptly into a deep sleep, and took about a 4.5 hour nap by accident! It was perfect, and I woke up like a new woman! I can imagine many nights of truly restful sleep ahead. This mattress is amazing!
