Features

  • STAY COOL- This Extra Frim King mattress was thoughtfully designed to allow maximum airflow, beginning with 3D soft knit fabric on the top cover which is breathable and skin-friendly, absorbing moisture. Underneath, innerspring coils work in tandem to help disperse heat. By regulating body temperature, reducing sweat and discomfort, it promotes deeper sleep stages, and enhances the overall sleep quality of your sleep for a more restful night.
  • POWERFUL SUPPORT- The 14 Inch Extra Firm King Mattress is 7-zone innerspring, with hundreds of pocketed coils that provide exceptional lumbar support and will closely conform to your body regardless of sleeping position for a comfortable night's sleep. The individually pocketed coils not only deliver excellent support but also ensure superior motion isolation, minimizing disruptions from your partner's movements throughout the night.
  • FOAM ENCASED EDGE- This Extra Firm Feel Mattress in a box features multiple support layers that The difference between this mattress and others is that it uses a sponge to wrap the edge of the mattress. It uses a high-density support sponge to wrap the edge of the mattress. The purpose of this is to prevent sinking and falling when getting in and out of bed or sitting on the edge of the mattress to rest. It is very suitable for the elderly.
