I've had my mattress for about a month and am so pleased. I like a softer matress and was afraid of the reviews about its firmness, but we are completely happy. The mattress expanded to the full 11 inches and we were able to sleep on it within hours of opening the package. The smell did not bother us at all. The best part about it is the lack of motion transfer. I no longer get woken up when my husband turns over. For added softness, we put a 3 inch mattress topper on it, and regular king sheets fit just fine without pulling up. We couldn't be happier. And the value - wow. We got our solid wood platform bed and mattress from Overstock for less than what a mattress set alone would cost.
