Key item features

  • Comfortable Firmness: This King mattress offers a medium-firm feel, combining memory foam and 660 pocketed innersprings for balanced support and pressure relief, specifically targeting the neck, shoulders, back, and hips.
  • Cooling Comfort: Featuring a fiberglass-free, skin-friendly knitted top cover and three layers of memory foam, including a cooler memory foam layer, to disperse body heat and maintain an ideal sleeping temperature.
  • Targeted Support: The 5-zone pocketed innerspring design (2.0/1.8/2.0/1.8/2.0mm) provides targeted, extra firm support in specific body areas to alleviate pressure and pain.
  • Motion Isolation: Individually wrapped pocketed springs work independently to minimize motion transfer and reinforce edge support, ensuring undisturbed sleep.
  • Spinal Alignment: The memory foam intelligently contours to the body, supporting the back, neck, and shoulders to promote proper spinal alignment and ease pain.
  • Certified Quality: Constructed with CertiPUR-US certified foam, ensuring durability, an odor-free experience, and adherence to quality standards.

very comfortable

Box came undamaged and on time. Couldn't wait to try it out and was not disappointed! It is so soft and comfortable my other memory foam mattress was killing my back it was so stiff. I will highly recommend this and the price is a great price considering the thickness etc, great thing is you don't feel the springs like some mattress

Good Value

This is nice for the price. I don't have any complaints. It is comfortable. I did add a mattress topper that I already had, but rested on just the mattress and it is good enough. There is definitely better out there but for the cost, this wins. It does not cave in on the edge when you have your legs over the side. I got the 12" mattress and it is 12"
