After sleeping on the mattress for over a week I have to say this mattress takes some getting used to in how firm it is. It has virtually no give when you get on to it. The first couple nights I didn't sleep too well, since then my body has gotten used to it and I have been sleeping a lot better. It is a very tall mattress but still works with regular sheets. You will barely notice any movement from your partner with this mattress which is great and a big change from my prior mattress. The mattress itself looks and feels very high quality and looks like it will last a long time. If you buy a extra firm model just make sure you and your partner really want your mattress to be very firm and not sink into it at all. I ended up purchasing a mattress topper for it because my wife doesn't like the firmness as much as I do. Overall I would recommend this Beautyrest though.
