The 10 thick Tomorrow Sleep mattress blends three unique layers of memory foam and innerspring. You can choose from two firmness levels to get you the sleeping comfort you deserve.

The Comfort layer of the medium-firm mattress has three layers of specialized memory foams. The 1 inch thick top layer, Tomorrow Cooling Open-Cell Memory foam, contours your body for an initial soft feel. This foam has phase change material to draw heat away from your body. The open-cell structure further promotes heat dissipation to let you enjoy an optimal sleep temperature.

The half-inch Tomorrow Pressure-relieving Gel Swirl Memory foam also enhances the cooling of the sleep surface. The gel absorbs motion well and gives the mattress a little bounce while preserving motion isolation. The 1.5-inch Tomorrow Dynamic Response Memory foam provides the mattress with its medium-firm comfort. This responsive foam has a subtle bounce to make moving in the bed easier. You can change sleep positions comfortably without any misalignment or stress and pain in joints.

The Comfort layer of the medium-soft model is a blend of two types of memory foams. These soft foams give the mattress a medium-soft comfort. The 1-inch thick Tomorrow Cooling Open-Cell Memory foam regulates the sleeping temperature for a cool slumber. The open-cell structure promotes ventilation whereas the phase change material draws heat away from your body.

Next is the 2-inch Tomorrow Pressure-Relieving Gel Swirl Memory foam with enhanced conforming ability. This combination provides excellent pressure-relief, localized support, and heat regulation. The gel makes the sleep surface a little flexible to prevent the stuck feel.

The Support Layer is same for both firmness models. The 6-inch thick Tomorrow Individual Support Pocket Coil System offers the necessary bounce to the mattress. The flexible coils provide deep compression support to the heavier persons. The resilient springs allow you to change sleeping positions easily. Since wrapped springs move independently, they conform to every sleep position and body type well. The individually packed steel coils improve motion isolation. The gaps create free air passage for heat ventilation.

The Tomorrow Ventilated Foam Rail System encases the pocketed coil layer from all sides. This foam secures mattress edges to prevent roll-off sensation and resists sagging too. The Rail System is polyfoam with holes to aid the airflow through the mattress.

The Base Layer is a high-density polyfoam that provides a stable base for the whole mattress. This foundational foam preserves mattress structure and improves its durability. The polyester and nylon mattress cover is stretchy and breathable. The mattress cover facilitates the heat regulation system of the mattress. The cover is easy to maintain and spot clean. If you are sharing the bed with kids, use a waterproof mattress protector as a precaution.
