The Slumber mattress is soft to the touch with a nice bouncy feel. Despite the comfortable foam layers, you don't sink into this bed, but rather lie on top of it. The cover is soft, and the foam layers add some slight contouring.

We found the Slumber mattress to be really firm, and rank it 8/10 on our firmness scale. We recommend this bed for back and stomach sleepers.

Construction Key Points

  • The Slumber mattress is 12" thick.
  • Sleepy's Slumber model is an encased coil mattress.
  • Slumber has a variety of unique foam layers, supported by nano coils.
  • Cover: A designer knit stretch cover is soft and inviting.
  • First Layer: Two quilted foam layers, one made from high-density, soy-based foam, give a soft top feel this mattress.
  • Second Layer: A gel infused memory foam layer and exclusive 5-zoned encased coils keep things cool and provide excellent transition support.
  • Third Layer: Ultra-wide, foam-encased edge support and high-density, shock-absorbing base foam give consistent bed support and excellent motion isolation.

Support & Motion Isolation

The Slumber mattress has an ultra-wide, foam-encased edge support system. Due to this, the entire bed has consistent support, and you feel very secure on the edge of the bed. This allows couples to take advantage of the entire space of the bed.

Motion isolation is excellent with the Slumber mattress. Individually wrapped encased coils minimize motion transfer allowing you to sleep undisturbed.

Reasons to Buy a Slumber Mattress

  1. The Slumber mattress is an excellent luxury mattress. It's made with high-quality, Certi-PURE certified materials and layers of comfort.
  2. Good motion isolation is very important for couples with active sleepers. The feeling of your partner getting out of bed or tossing and turning is disruptive to sleep. The shock-absorbing base foam in this mattress does an excellent job of isolating most motion so both sleepers are able to rest undisturbed.
  3. If you get hot in your sleep, this mattress is perfect for you. Cooling gel-infused memory foam helps dissipate body heat while coils allow for better airflow. Sleep cool with the Slumber mattress.
