Review: Was trapped undecided between this and some offerings at Costco. Honestly I don't make that much so even what would normally be thought of as somewhat inexpensive or affordable for a mattress took no small amount of savings. I wanted to get it right and my gosh was it agonizing to choose. Such an unreasonable and almost senseless gamble to buy a mattress online without ever testing it in person especially a mattress in a box, typically mass made in china and drop shipped by some third party company that charges multiple times it's actual cost, you know what I mean. Now I typically take careful consideration of negative reviews especially in issues that are consistently reported and for that reason, despite all the stellar reviews on other websites, every mattress within budget had a repetition of negative issues. This mattress seemed the most consistently well reviewed across several websites, and all things considered I was willing to go quite a bit more over budget for something so vital as a mattress. With all that out the way I'll say it now, this mattress has been so much better than I could have hoped for. It's soft, very soft, mostly dues to the extra thick topper but with the support of an actual coil frame. I personally cannot stand foam mattresses, and all the nice spring or hybrid mattresses where just too much. Then again my main concern with hybrid mattresses are the hazardous materials used in manufacturing. They check all the boxes for flame resistance and what have you but the toxicity was not something I wanted to risk. Imagine having to de-gas your mattress and even then the materials aren't going to decide to not be carcinogenic just because you sleep with them. It's isn't verifiable what these offshore manufacturers are using but this mattress is made in the US. I did spent quite a bit of time researching into it's safety and manufacturing and since this is too much already for a simple review, I'll end this by saying: this mattress is sooo comfortable, well made, and safely made. (Just don't jump on it like a fool and complain the support gives out or pile drive the thing with all 400 something pounds of yourself after a long day and then go on desertcart to complain when the knit cover starts to inevitably tear. It's still a product that needs to be taken care of just as everything else).
Review: I adore my new mattress! This has saved my back and neck/shoulders a huge amount of pain and improved the quality of my sleep 10-fold. I highly recommend this mattress for anyone with Fibromyalgia. It feels a little bit firmer than I really like (my rationalefor 4 stars in comfort), but when you wake up every day feeling good compared to never refreshed and never not achy, it gets an actual 4.5 stars for comfort. You cannot knock this mattress!!!

*by M***E on 10 September 2023*

I love this mattress, my prior mattress was an expensive “Vera Wang” king size pillow top mattress and it cost me an arm and a leg. I bought the “queen 12 inch” version of this mattress when it was on sale for 40 percent off under 500$ and I was skeptical but had read good reviews from other customers and they weren’t lying. This bed is incredibly support and I am a plus size woman, it’s supportive but comfortable all around. Supports me and my pets and needs perfectly. No odd or off smells when arriving. It said to wait 24-48 hours but practically came risen out the seal and put on my frame within hours was ready. I love this mattress and the material, I am not hot when I sleep on it either, my back hurts no longer and I sleep soundly. I also have a larger chest and love to sleep on my stomach but my old mattress did not allow this. I was having shoulder pain as well, it’s way improved and I can sleep in all positions. I love it!!! I would recommend! I know the picture doesn’t do the mattress justice but still shared, you won’t regret it.
