Hybrid Contour Meets Balanced Coil Support
The Serta Perfect Sleeper® Cascade Bluff Hybrid Medium Mattress blends cooling EverCool® Supreme Memory Foam with Serta's 920-density Q4™ Support System in a 13.5" hybrid. 5 Zoned Comfort targets the lower back, and a CoolFeel® Plus cover with breathable wool keeps the surface refreshingly cool.
Medium Hybrid Comfort, Explained
A hybrid lets you settle into foam instead of lying on a quilted top, so the Bluff Medium contours closely to your curves while the linked coils keep you lifted and easy to move. The medium feel suits side, back and stomach sleeping, which makes it an easy choice for couples. You get the cradle of memory foam with the bounce and airflow of coils.

Why You'll Love It
Designed to Ease Aches
Zoned coil support and pressure-relieving foams are designed to help relieve aches and back pain by keeping your body in natural alignment.
Sleeps Cool
CoolFeel® Plus Fabric and a breathable wool layer help regulate temperature, while the coil core lets air move through the mattress.
Built to Last
Linked 4-in-1 coils share the load evenly across the bed, helping reduce sagging and body impressions over time.
Hybrid Balance
You lie directly on cooling memory foam for a contouring feel, with responsive coils underneath for lift and easy movement.
Support Where Your Body Needs It
Your shoulders, hips and lower legs press into a mattress the most, while the lower back and upper thighs need extra lift. 5 Zoned Comfort answers both, with plusher zones where you press in and firmer zones where you curve, so the Cascade Bluff Medium Hybrid keeps your spine aligned from head to toe.

CARE
- Use a mattress protector to guard against spills and stains and extend the life of your mattress.
- Don't apply liquids or cleaners directly to the mattress; moisture can stain the fabric and break down the foams.
- To freshen a soiled area, sprinkle baking soda, let it stand about 15 minutes, then vacuum. Repeat as needed and air the mattress out.
