Serta Perfect Sleeper Pro Kensington Medium Mattress

Zoned Hybrid Support, Built Medium

The Kensington Medium is part of Serta's Perfect Sleeper® Pro line: a 5 ZoneActive™ hybrid design pairing zoned coils with graphite-infused latex foam. In the Medium feel, the coils and latex foam are balanced evenly, giving side, back, and stomach sleepers alike a versatile surface that cradles pressure points without excess sink.

It's built with 2" of graphite-infused True Response™ Latex Foam, CoolFeel™ Pro Fabric, and PillowSoft® Aire, all engineered to minimize partner motion and support natural spinal alignment through the night.

Feel & Support

Built for a Medium Feel

The Kensington balances zoned coil support with graphite-infused latex comfort layers, giving you enough cushioning to relieve pressure points while keeping the supportive feel that works across every sleep position.

Why it matters:

  • Balanced sink — cushioned enough for side sleepers, supportive enough for back and stomach sleepers
  • Zoned alignment — 5 support zones keep your spine aligned all night
  • Consistent support — latex foam adds comfort without masking the coil support underneath
Cooling

Cool-to-the-Touch Comfort

Why it matters:

  • Instant cool-to-the-touch feel — CoolFeel™ Pro Fabric cover
  • All-night breathability — graphite-infused latex and PillowSoft® Aire's rippled design promote airflow

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.
