This bed is 1000 times better than the one we had before. Despite its "firm" title, it still gives give in the right spots, so once you sink in to this puppy, you never want to get out. My only complaint is that this bed was a solid 3 inches thinner than my old california king. I still wouldn't change it for the world, but I did pout a teeny bit when I saw the difference. Also, the base isn't one solid base. Instead its made up of two twin sized bases. It doesn't change a thing for me, its just an important FYI to any potential buyers.
After a disappointing buy at a local store this mattress is a pleasure to sleep on. have only had the mattress a few months but no sagging and comfortable enough. Our world class eurotop is softer and more luxiurious feeling but after the pillow top (non beautyrest) mentioned above, my wife convinced me to get a firm mattress and buy a separate top if necessary. It is plenty comfortable for me now despite an occasional sore shoulder. we have the Luxury firm. What a game it was figuring out that Beaurtyrest gives their mattresses different names for every retailer (same mattress).
