We were reluctant to keep the mattress after the first night, because we were so use to our old mattress, but after the second night we were pretty happy with it. The only complaint is it seems to conform to your shape and can form a bit of a form to you, which can be annoying. We have to flip it around frequently to keep it from staying in one form.

Ii purchased a mattress and a adjustable base. It is the first adjustable base I have purchased - it is taking me a while to get use to it and to figure out how to use it best. My only complaint is I had a terrible time trying to locate the serial number. The mattress and base were delivered a couple of weeks ago and the furniture company came back today to deliver a chair. I had them find the serial number for me. They stood the bed up on end (something I couldn't do - the mattress it too heavy for me to lift) and couldn't find it on the top end and tuned it sideways and found it on the underneath side in the middle. How on earth was I suppose to find that?

We started our Sealy experience with the soft version of this mattress. However, we had to exchange it due to waking up with lower back pain every morning. We figured the medium version would help provide that additional support that we needed. We also purchased Sealy's standard box frames to go with the bed. We had the same mattress for 10 years prior before deciding to try Sealy. I never had any issues with back pain or being uncomfortable, but we wanted to upgrade to a king size bed and had the room with our new house. I've never so immensely regretted a purchase until this one. Every morning I wake up with a sore back and shoulders. I toss and turn all night, not even being able to sleep on my back because the bed is so unsupportive. For a medium bed, it feels like my butt sinks to the floor and my shoulders barely move. No proper support to be found. I have never hated a bed more before. If you are a back sleeper looking for a comfortable, supportive mattress, this is not it. I wish we had a way out from this mattress, but we already used our exchange thinking we would only be getting a more supportive bed. Instead all we got was lost sleep and some of the worst back and shoulder pain I've ever experienced. Stay away from this mattress.

One suggestion, if you are purchasing the adjustable foundation, have 4 9-volt batteries available to be installed in the frame. They can be installed later and we were shown how to do it. The mattress does not have any odor and is very comfortable. Looking forward to some great sleep!

Was just delivered today. We went with the hybrid to gain a little more support than a full foam mattress, but we needed the joint relief of the foam. We've already spent an hour on it and we think we're in love. It does have a semi-unpleasant smell (just like they said it would), but it's light and doesn't seem to be any issue. I'll update more after a few days.

This new mattress is incredible. It is helping my husband's pain and the new pillows helps straighten his back again. He feel less pain on his upper nerve on his left arm. I am so grateful we purchased this bed. I am so sold on mattress firm. The staff on Warner rd was very helpfull , patient & amazing. I will buy again from mattress firm.

Compared against Tempurpedic, Serta, and Select Comfort. Unbelievable support and comfort. Back issues we had during our Select Comfort years have been eliminated. Does sleep a little warm but not a deal breaker. Also purchased the adjustable base and couldn't be happier.

[This review was collected as part of a promotion.] This mattress is amazing! Its super comfortable, much more so than my old mattress. It took a few nights to adjust, but its made a huge difference in my sleep. I feel more rested. My fitbit it showing higher sleep scores than it used to and my back pain is way less than it used to be. Super glad to have this in my life now, its made all the difference!

I purchased the Sealy Ultra Plush Gold mattress and I love it. I sleep on my left side most of the time and back some. I would wake up in the mornings and my shoulder and hip would hurt. However, I now get a wonderful nights sleep and wake up refreshed! I love my bed!

Compared to my last hybrid mattress this one is definite elite, and very solid. I am a heavy man and my wife light weight and it conforms to me and does not hurt my shoulders because they are broad and I can tend to sink and get stuck in my position which did cramp me until I got this mattress. The mattress is also cool, so in the middle of the night when the heat turns on it stays cool, no need to take covers off.
