Serta Perfect Sleeper Oasis Sleep 13.25 inch Plush Mattress

Classic Support, Built Plush

The Oasis Sleep 13.25" Plush is part of Serta's Perfect Sleeper® line: a quilted tight-top innerspring mattress built on an 825-coil Custom Support Coil System for zoned, cradling support with minimal motion transfer. In the Plush feel, the comfort layers add extra give at the shoulders and hips while the coil system keeps you supported underneath.

It's built with PillowSoft® Aire Foam for cushioned airflow, a gel foam lumbar support band for the lower back and hips, and a CoolFeel™ cool-to-the-touch cover — all on a 13.25" profile with an extra-deep foam rail edge.

Feel & Support

Built for a Plush Feel

This is the Plush option in the Oasis Sleep line: extra cushioning at the shoulders and hips, with the coil system still doing the underlying supporting work.

Why it matters:

  • Extra cushioning — a contouring feel for side sleepers
  • Pressure relief — softer comfort layers ease pressure at the shoulders and hips
  • Supportive base — the coil system keeps you from sinking too deep
Cooling

Topped With CoolFeel™ Fabric

A CoolFeel™ cool-to-the-touch cover sits on top of the comfort layers, so the sleep surface starts cool and stays comfortable through the night.

Why it matters:

  • Cool-to-the-touch — a noticeable cooling sensation from the first moment you lie down
  • Breathable comfort layers — PillowSoft® Aire Foam's rippling design promotes 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.

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.

Perfect Sleeper Innerspring FAQS

It is Serta’s innerspring Perfect Sleeper line updated for consistent, restful sleep: an 825-coil density support system, zoned comfort and pressure relief, contouring foams, and a cool-to-the-touch cover made with CoolFeel™ fabric—designed for comfortable sleep night after night.

Zoned Support means ergonomically designed support zones with alternating levels of firmness to help keep your body aligned as you sleep—support where you need it and comfort at key contact areas.

The 825 Edition Custom Support System provides contouring, cradling support and helps minimize motion transfer. An extra-deep foam rail is designed to reduce edge roll-off and extend the usable sleep surface.

It is a gel foam band positioned to add lumbar support—helping support the lower back and hips for pressure relief where many sleepers need it most.

Yes. The mattress is topped with a cool-to-the-touch cover made with CoolFeel™ fabric, and PillowSoft® Aire Foam is designed to promote airflow through its gently rippling design for a more comfortable sleep environment.

Comfort levels include Standard (Firm, Plush, Plush Euro Top), Enhanced (Firm, Medium, Plush, Plush Pillow Top), and Ultimate (Extra Firm, Firm Pillow Top, Medium Pillow Top, Plush, Plush Pillow Top). Sizes typically include Twin, Twin XL, Full, Queen, King, and California King—confirm availability for the level you want.

Yes. It is compatible with most setups, including traditional frames, box springs, platform frames, slatted frames, bunky boards, and adjustable frames.

Serta advertises a 100-night trial, free shipping and returns, and a 10-year limited warranty on this line when purchased under those terms—see Serta.com for full details, exclusions, and delivery timing in your area.

Use a mattress protector to guard against stains and spills and to support mattress longevity. Do not soak the mattress or apply liquids directly—those can stain fabrics and damage foams. For spots, sprinkle baking soda on the area, wait about 15 minutes, vacuum, and repeat as needed; air the bed out when possible. Foams are CertiPUR-US® certified for tested content.
