First of all I want to start and say this mattress showed up so quickly it was insane. The box is a little heavy so you need an extra hand to bring it inside but otherwise it was so easy to set up. We simply cut open the plastic on our bed, pulled it off and allowed it to poof up all on its open. It’s incredibly comfortable, even right out of the box it was absolutely amazing. I’ve had nothing but amazing sleep. I truly would buy this mattress over and over again it’s such a good deal for the cost of the mattress.

Been pretty comfortable and firm. It's helped with my back issues so far. I loved how the price wasn't too expensive and its still a great mattress. I let it "puff" up for about 3 days. Probably didn't need to be that long of a wait but it was worth it

Mattress is comfortable. I realize firmness is highly subjective, but I would, for sure, describe it as medium firmness. We've had it for a couple of weeks now, and it seems ok on my side; husband, who weighs more, has a divot already starting to form. Alas, I don't have high hopes for finding a reasonably-priced mattress that doesn't do that.

Almost every description detail of this product is a lie it gets one star for accurate sizing and on-time shipping and looking slightly like the picture. Loses a star for not having the foam boarder around the springs infact there is no faom in this matress at all just inner srping with a pillow top., loses another star for not having pocket coils just inner spring, loses another star for being 98% spring and 2% pillow top loses ZERO PERCENT FOAM loses the last star for the stench, inaccurate discription and dismal fit and finish . It has a big seam and two inch layer where foam should be but there isn't. Not worth the 350 I paid for it after tax this should be a 99 dollar matress at at should have just picked one locally. Even though waiting for it to puff up, but having had dealt with many a matress in a box I can absolutely say this does not have the foam layers pictured. This is absolute junk do yourself a favor and move on form this becaise now I have to take a day and wait for amazon to come pick this piece of junk up
