At $555, this mattress is the best deal out there at amazon.com. I bought this after reading all 13 previous reviews and they are all exactly right. The 5.5lb density is pretty firm- I was afraid at first it would be TOO firm. We are both bigger people around the middle, and we both LOVED sleeping on it. So feeling how firm it is with your hand can be a bit mis-leading- it is SUPER comfortable. I sleep all over- on my sides, on my back, and now with this king size memory foam mattress I can even sleep on my stomach, which hasn't been comfortable for me on a "regular" mattress since about high school. It's 2 layers: 3 inches of the elastic memory foam (which is body-heat sensitive- the latex memory foam is not) and then 7" of "High Resilience Polyurethane Base Foam." It expanded to full size very quickly. We slept on it about 3 hours after opening it and the smell that everyone talks about wasn't too bad. 

This morning the smell was totally gone, and it wasn't that bad to begin with. The transfer of motion is almost totally gone as well. We used to sleep on a regular mattress with a memory foam topper, and I always thought that was "just as good." Trust me, it's NOT.

We were always waking each other up. Now we can both move around and the other one doesn't feel a thing, and therefore doesn't wake up. Even our dogs getting on and off the bed all night didn't wake me up. One thing to note is the warranty. It does not cover shipping costs, comfort (ie: if you don't like how firm or soft it is, too bad), does not cover the zipper, and is voided if the mattress is at all stained, scuffed, otherwise damaged, and if it was not kept on a flat solid surface (ie putting it on a slatted base or regular box springs will void the warranty). If you can check out what density you like at a local store beforehand that would probably be best. We lucked out and happened to like the firmness without knowing beforehand how it would be, so we won't be returning it anytime soon. Ours arrived on the first day of the shipping window, vacuum sealed, then wrapped in 3 layers of heavy plastic and tied with 4 straps. It was not damaged at all, and was really easy to un-wrap and lay out. We have absolutely no complaints. I'm recommending it to all our friends and anyone who reads this.

One last thing before I forget, as another review stated- memory foam and the base foam soak up spills like a crazy sponge. The reason we bought this was because our new dog peed on our old memory foam mattress pad, which was only 4 inches thick- and we just could NOT clean it. I tried EVERYTHING, and ended up basically SOAKING half the mattress pad in kids'n'pets cleaner, to no avail. It still smelled and was still stained. I can't BEAR the thought of spilling anything on the new king size memory foam mattress (seriously, even a little tiny spill will be obnoxious), so we are getting a plastic cover (which also cuts down on dustmites, which I am highly allergic to), and I recommend to anyone who buys this or any other memory foam product to get a plastic cover for it. Otherwise one tiny spill can ruin your investment.
