How It Feels

Plush Pillow Top Comfort, Explained

Plush Pillow Top is soft, deep and cradling. The extra layer on top lets the shoulders and hips sink in comfortably, easing pressure for side sleepers, and the denser 920-coil core keeps the bed from feeling hammock-like. If you want a luxurious, plush feel with dependable support, this is it.

Ideal for: Side sleepers who want a deep, plush pillow top

What's Inside the Cascade Range Plush Pillow Top

  3. 3QuiltLoft™ Memory Foam

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.

Classic Innerspring Feel

A responsive, on-top-of-the-bed feel that's easy to move on, with the airflow and bounce people love about coils.

Zoned Support

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 Range Plush Pillow Top 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.

10 Year Limited Warranty

Serta® mattresses or foundations used with proper support are protected by a 10 year limited manufacturer’s warranty. Serta products are warrantied against manufacturing defects in workmanship and material (excluding covers and handles, except for handles on iSeries and equivalent level mattresses).

Exclusions

  • Bedding sold “as is”, or floor samples, or bedding purchased from second hand parties, non-retail establishments or received as a promotional item.
  • Bedding height
  • Corner guards
  • Bent perimeter border rods due to moving or bending the sleep set for innerspring models
  • Replacement of another piece in a sleep set unless it is also defective

  • Mattress fabric (except as noted in the Warranty Coverage Detail section for an All Foam mattress)

Term

The warranty coverage runs from the original date of purchase. Replacement of the mattress or foundation does not extend its limited warranty or begin a new limited warranty period. Your warranty period is based on the code printed on your white law label as indicated on the Warranty Code Chart. The duration of any applicable implied warranties, including but not limited to the implied warranties of merchantability and fitness, shall not exceed the term of this limited warranty. (Some states do not allow limitations on how long an implied warranty lasts, so this limitation may not apply to you.) Serta® shall not be liable for incidental or consequential damages that result from the use of your Serta® product. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion may not apply to you.) No expressed or implied warranties are extended to persons who purchase the product from anyone other than Serta Simmons Bedding Company or its authorized dealers, and all warranties to such persons, including the implied warranties of merchantability and fitness, are hereby excluded.

Service

If your Serta® mattress or foundation fails due to a manufacturing defect, the exclusive remedy under this warranty will be replacement of the defective product in the U.S., Puerto Rico or U.S. Virgin Islands. If the Serta® product you purchased is discontinued at the time of replacement, a current model of comparable quality and value will be selected. To receive service under the terms of this warranty contact your original Serta® dealer. If your original Serta® dealer is no longer in business or you have moved outside the service area, please contact Serta Customer Service at 1-888-55-SERTA (1-888-557-3782) between the hours of 9am to 5pm EST Monday - Friday. A copy of original bill of sale is needed to determine original date of purchase. Model name label and law label must be provided to identify the bedding and validate this warranty.

Your Rights Under State Law

This warranty gives you specific rights, and you may have other rights, which vary from state to state. This warranty is extended only to the original purchaser from Serta Simmons Bedding Company or its authorized dealers.
