Review overview

This giant friend is like a “fluffy monster” in your room. We call it a monster just because of its King size and this should be a spectacular purchase ever if you are a side sleeper and you want the fanciest bedroom but at an affordable price. The mattress comes with a TriComfort design. There are three layers:

The top one is a 2.5 Suretemp memory foam which provides a luxuriously soft cradling, following your curves and relieving pressure points of side sleepers.

The second is a 2.5-inch air dissipating layer. It absorbs heat and prevents temperature to build up. The bottom one is a 9-inch base supporting layer. It has a high density to give enough support to heavy sleepers at night.

The three layers form a very thick structure which reduces motion. When your partners turn their bodies or make a movement, you don’t even know it!


  • Great support and appropriate comfort level for averaged body ratio sleepers, which has been researched and analyzed by Sleep Innovations
  • It provides higher quality sleep and solves the problem of heat-trapping of the Dreamfoam
  • A reasonable US mattress with a strong 20-year warranty


  • Some sleepers in hot or tropical climate complain that because of the top soft layer, they sink in the mattress and find it hotter than other types of mattresses. So a reminder before you buy it, make sure it fits the environment also!
