Serta® Cascade Range 14" Innerspring Extra Firm Tight Top Twin Mattress

Our 920-density 4‑in‑1 coils are designed to evenly distribute your weight and provide long‑lasting support—helping you stay comfortable and supported all night

This zoned coil system features alternating plush and firm areas that contour to your shoulders, back, and hips for more balanced, body‑hugging comfort

This conforming quilt‑layer foam gently contours to your body, adding plush, pressure‑relieving comfort right at the surface for a softer, more comfortable sleep experience

Fabric treated with cooling performance technology pairs with a breathable wool layer to help create a refreshing, cool-to-the-touch feel as you settle in—so you stay comfortable from the moment you lie down

CertiPUR-US® Certified means our foam was tested for and is free from harmful chemicals and gasses

Adjustable base compatible, as well as most frames and foundations, including: traditional frames, box springs, platform frames, slatted frames, bunky boards

To protect your mattress from stains and spills, we highly recommend using a mattress protector; this will also help with the overall health and lifespan of your mattress

We do not recommend applying liquids to the product; applying liquids may stain the fabric and make the soiled area worse; moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product

We suggest applying baking soda to the soiled area, let stand about 15 minutes, vacuum, and repeat as needed; air the product out as much as possible
