Style: Level Three Extra Firm
Size: King
This mattress is very, very firm. I love it, but my spouse says it's like sleeping on a sidewalk. So we compromised and added a memory foam mattress topper. It's still very firm, but the mattress topper makes it just a little bit more soft. For back pain sufferers like me, it is wonderful. But be aware that you very much sleep ON TOP of this mattress, and you will not sink down even the tiniest bit INTO it. If you sleep in your back like I do, it is wonderfully supportive. It might be too firm for side sleepers. Also you should know that this mattress is very heavy. But it seems to be great quality, at least so far.

Pretty high mattress, but also the most comfortable I have ever slept on. Has handles on the side and is very easy to move around if needed. It is heavy and we did need two people to carry it into the bedroom. Also very happy it is a black mattress so dirt can't be seen that easily. It is a firm mattress and holds my husbands weight better than any other one we had before. I can't feel him turning around at night so I don't get disturbed. Very cool! Our sleep has improved drastically, because I do not wake up as often as I used to. The only beef I have, is that it arrived with a button missing in the middle of the mattress. For this price this should not be happening. Also the mattress itself was not well protected from getting dirty. Other than that we love the quality of the mattress and there is no sinking into the mattress. Like I said pretty firm, yet very comfy. I can clearly see the difference between a cheaper mattress and a more expensive one. The value for the price is definitely there. Can recommend this mattress.

We got the Level Three Medium Pillow Top, and I can honestly say we’re super happy with it! We had a $4,000 mattress before this that we just couldn’t get comfortable on; it was way too firm and never softened up, no matter what we tried. We added toppers, pads, everything. Nothing helped. So when I came across this Beautyrest, I decided to give it a try, and I’m so glad we did. Growing up, I had a Simmons mattress and always loved it, so it’s nice to have one again. This one feels supportive but still plush enough to sink into just a bit. It’s a little firmer than I expected, but still really comfortable; I sleep through the night now without waking up in pain. The pillow top adds just enough cushion without feeling too soft or squishy. As far as quality goes, it seems really well-made. The stitching looks solid, the fabric feels durable, and everything about it gives that “premium” vibe. I also really like that it didn’t come compressed in a box. It did arrive in a large box, but not rolled or vacuum sealed, and it was double-wrapped in thick plastic for protection. It is heavy, though, definitely a two-person job! My husband was out of town for work when it arrived, and I was so thankful the delivery guys brought it inside for me. I never could’ve moved it by myself. The motion isolation is excellent. My husband tends to move around a lot at night, and I barely feel it anymore. That alone makes a huge difference in how well I sleep. Plus, the cooling surface really does help regulate temperature; I haven’t woken up over-warm once since switching to this. It’s holding up beautifully so far, and I even like the black design of the mattress itself. Nobody but me sees it when I change the sheets, but it still looks nice and sleek. Overall, this mattress checks all the boxes: supportive, well-made, comfortable, and truly built to last. It’s not cheap, but after wasting money on beds that didn’t work for us, I feel like we finally found a good one Just make sure you’ve got someone to help when it arrives!

I have to update this review after only a month. What started out amazing, like many a relationship, failed quickly. My back is stiff and sore, and I am waking up unrefreshed and grumpy. It is firm, but uneven. I am seriously disappointed and frustrated. This is supposed to be a high end mattress!! Here's the thing, I think: it is a very thick mattress and firm to lie on, but the mattress itself has too little structure. We noticed right out of the box how floppy it was, and how it wouldn't even lean against the wall without bowing. At minimum you absolutely HAVE to have a box spring. We have frames that are supposed to substitute for box springs and always have, but not here. Both the sides of the mattress have sinking spots already, and last night felt as though it was sagging a bit in the middle. It was minor and went mostly away, but this mattress is only a month old!! And the trouble with having a box spring is that you are going to end up with a two foot high bed. The mattress is 16 inches to the top of the pillow top, although where the actual mattress stops is closer to 14. But even still, that's awfully high for a bed. For reference, we are both 55 and both weigh somewhere around 165. He's closer to 160 and I'm closer to 170, so I took the average. We have tried rotating the mattress and that helped for a day or two, but I'm going to have figure out what to do with this thing. I think for a single person who sleeps in the middle (mine is a Cal King) it would be ok, but it did not work for this married couple. :(
