  • Well, Made EXCELLENT Mattress Not to hard not to soft just right.
Item Firmness Description: Firm Item Thickness: 14.0 Inches Size: King (U.S. Standard)
This is a great mattress it has a good bounce and keeps a 220lbs. man near flat anywhere on the mattress with just enough give in the springs just excellent I can't feel them with the thick top layers of paddings this is the best mattress I have ever owned Love it the mattress it is true to size and I think will be good for over the 10 year mark. Be very careful when opening the mattress use the supplied tool and just be smart it will spring open with a lot of force, watch your face. I can't say enough good about this mattress the fabric is great also. You will not want anything to do with your old mattress so just have them take the old one away. LOVE THE MATTRESS. ... show more

  • Soft and bouncy, better than expected.
Item Firmness Description: Firm Item Thickness: 14.0 Inches Size: King (U.S. Standard)
For the price I paid, it has been a great deal. Bouncy and supportive with good edge support. I needed a softer bed and now I sleep very well. Way better than I expected. It has been about 2 weeks since I set the mattress up and it went to its intended size within minutes to an hour. At this point, I would definitely purchase again. ... show more

  • Don’t question this. Just buy it!
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. ... show more

  • Was a good price and not lumpy.
Very thick and heavy. Kinda firm. We had to use a mattress pad for softness.
