Just received my king, extra firm set today and let me tell you, it is like lying on a boulder. NO give whatsoever. I do highly commend the delivery company. They were EXCELLENT in their communication and did everything exactly when they said they would.

Just received it today. Looks good, but I'll have to try it out before I can submit more information.

Seems comfy but the real test will be when my husband sleeps on it since he isn’t comfortable in any bed so hopefully this is the winner!

So far so good. Definitely feel a difference compared to a previous “extra firm” mattress I had from another manufacturer

It is as expected - For the two night we had it, as of now it is delivering resful nights and the support is extra firm, as we like.

this mattress has helped us get a better nights rest. I bought the extra firm and added a gel topper and we sleep like babies.

Comfortable and supportive, but without a mattress top it causes neck and shoulder pain in the morning

Hopefully it stays that way my last Beautyrest Black was the worst mattress I ever got. I’m hoping this does better.

So far, so good. I’ve only had it 4 days and I actually do feel my back is doing a little bit better.

We've only had the mattress for one week, but my husband could feel the improvement in his back after just one night.
