The Cool mattress is made of high-quality foam and does a great job aligning the spine while you sleep. Phase-change gel top material adds pressure point relief as well as cooling effects. The support foam and memory foam layers provide a plush, soft feel. The ventilated cover keeps the mattress cool to the touch.

Despite how soft it is, we noticed there isn't much bounce to this mattress. This is probably due to the thick, high-density foam base.

We found the Cool mattress to be super soft and plush. We rank it 5.5/10 on our firmness scale. We recommend this bed for side sleepers.

Construction Key Points

  • The Cool mattress is 12" thick.
  • Sleepy's Cool model is a foam mattress.
  • Phase-change material gel top surface layer to dissipate heat.
  • Cover: A ventilated woven cover that is soft, inviting, and keeps cool.
  • First Layer: 3'' of contouring memory foam that alleviates pressure.
  • Second Layer: 9'' of high density support foam that cradles the spine.

Support & Motion Isolation

The Cool mattress has average edge support. The foam layers sink and collapse a little bit when sitting or lying on the edge. While not unpleasant, it can't provide a consistent feel from center to edge of the mattress.

Motion isolation is excellent with the Cool mattress. Multiple layers of foam and the gel top surface absorb motion transfer. Rest peacefully even next to a partner who tosses and turns a lot.

Noise is also kept to a minimum as the high-density foam base absorbs any sound from partner movements.

We recommend this bed for couples, as the motion isolation and cooling effects are very beneficial for sharing a bed with someone.
