Serta Perfect Sleeper Pro Valais Plush Pillow Top Mattress

Plush Cushioning, Built for Side Sleepers

The Valais Plush Pillow Top is part of Serta's Perfect Sleeper® Pro line: a 5 ZoneActive™ hybrid design layered under 4" of True Response™ Latex Foam and Cool Twist® Gel Foam. In the Plush Pillow Top feel, generous cushioning gives shoulders and hips the deep pressure relief side sleepers need, while a dedicated latex support core and zoned coils keep the spine aligned underneath.

It's built with CoolFeel™ Pro Fabric, PillowSoft® HD Foam, Cool Twist® Gel Foam, graphite-infused True Response™ Latex Foam, a Serta® Base Support Foam layer, and a 4" Latex Support Core, all engineered to reduce tossing and turning and support natural spinal alignment through the night.

Feel & Support

Built for a Plush Pillow Top Feel

The Valais layers 4" of True Response™ Latex Foam and Cool Twist® Gel Foam over a dedicated latex support core and zoned coil system, giving side sleepers deep pressure relief at the shoulders and hips while staying aligned.

Why it matters:

  • Deep pressure relief — plush layers cushion shoulders and hips
  • Zoned alignment — 5 support zones keep your spine aligned underneath the plush layers
  • Reduced tossing & turning — layered comfort reduces the need to shift positions
Cooling

Layered Cooling

CoolFeel™ Pro Fabric, Cool Twist® Gel Foam, and graphite-infused True Response™ Latex Foam work together to pull heat away from the body, so plush comfort doesn't come at the cost of sleeping hot.

Why it matters:

  • Instant cool-to-the-touch feel — CoolFeel™ Pro Fabric cover
  • All-night breathability — Cool Twist® Gel Foam and graphite-infused latex dissipate heat
Made to Last

Certified Foams, Backed for the Long Haul

CertiPUR-US® Certified & 10-Year Limited Warranty: The Valais Plush Pillow Top is 100% USA Assembled with CertiPUR-US® Certified foams and backed by Serta's 10-Year Limited Warranty, so your investment is protected for years of use.

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.

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.
