Description

Proactive Climate Control with Omniphase™ Technology

The FIVE SIDED™ + OMNIPHASE™ Mattress Protector is the gold standard in sleep temperature regulation. Unlike traditional cooling covers that simply feel cold, Omniphase™ actively absorbs, stores, and releases heat to maintain a consistent, comfortable microclimate all night long. Available at Texan Mattress for those who want total protection without the temperature swings.

Advanced Technical Features:

  • Omniphase™ Phase Change Material: This award-winning fabric sensing technology continually adjusts to your body temperature, ensuring you stay neither too hot nor too cold.
  • Tencel™ Lyocell Fiber: The moisture-wicking Tencel™ top layer is incredibly soft and eco-friendly, enhancing the cooling effect through natural breathability.
  • Complete 5-Sided Shield: Offers a 100% waterproof barrier for the top and all four sides of your mattress, protecting against liquids, allergens, and dust mites.
  • H2Pro™ Membrane: A lab-certified liquid proofing layer that allows air to flow through while keeping fluids out—eliminating the "crinkly" feel of cheap protectors.

The Ultimate Investment in Mattress Longevity

By combining the moisture-management of Tencel™ with the active regulation of Omniphase™, this protector doesn't just shield your mattress; it upgrades your entire sleep experience. It's the perfect fit for luxury memory foam or hybrid mattresses that tend to retain heat.

Care Instructions: Machine wash cold to hot. Tumble dry medium. Do not bleach.

Comfort Exchange & Returns

120-Night Comfort Guarantee

Quick answer: Eligible mattress purchases include up to 120 nights to adjust to the mattress. If it is still not the right fit, you may request one comfort exchange during days 101–120 after delivery. No comfort-exchange request is accepted before day 101, and the written eligibility requirements, fees and exclusions apply.

What does the 120-Night Comfort Guarantee include?

  • Time to adjust to an eligible new mattress before requesting an exchange.
  • One eligible mattress comfort exchange during the written request window.
  • Help selecting a replacement mattress of equal or greater value.

This is a comfort-exchange program, not an unrestricted risk-free return or refund promise. Product-specific written terms supplied with your purchase control if they differ from this general policy.

Exchange window

  • No comfort-exchange request is accepted before day 101 after delivery.
  • An eligible request must be submitted during days 101–120 after delivery.
  • The policy provides one mattress exchange.

Exchange value

The replacement mattress must be of equal or greater value. If you select a higher-priced mattress, you are responsible for the difference.

Eligibility

The original mattress must be in clean, sanitary condition and free of stains, tears, odors, abuse or other damage. Proof of purchase is required. Product-specific written terms supplied with your purchase control if they differ from this general policy.

Promotional items

If your purchase included free promotional items and you keep those items, their stated retail value will be deducted from the available exchange credit.

Items not eligible for a comfort exchange

Floor samples, closeout items, discontinued items, pillows, protectors, toppers, adjustable bases, foundations or box springs, sheets and other accessories are final sale unless otherwise stated in writing at the time of purchase.

Cancellations

Orders may be cancelled before processing begins. Once an order has entered processing, fulfillment or delivery preparation, cancellation may no longer be available.

Warranty claims are separate

A comfort preference is different from a manufacturing defect. Warranty claims are handled under the written warranty that applies to the specific mattress and are not governed by the comfort-exchange window.

How to request an exchange

Contact Texan Mattress with your original order information during the eligible request window. Our team will verify eligibility and help you choose the replacement mattress.

Quick answer

What should you know about FIVE SIDED™ + OMNIPHASE™ MATTRESS PROTECTOR?

FIVE SIDED™ + OMNIPHASE™ MATTRESS PROTECTOR should be evaluated by fit, protective coverage, surface feel, breathability, and the exact features listed by the manufacturer. Confirm your mattress size and depth before ordering, then review whether the product description specifies waterproof protection, which sides are protected, and how the protector is secured. A lower-profile protector is generally less likely to change the mattress feel, while quilted models can add a little surface cushioning. Breathable materials may help preserve airflow, but the complete sleep system and room conditions still affect temperature. This item includes free nationwide delivery and typically ships by UPS or FedEx. Reviewed by Larry Heilers using current Texan Mattress specifications and Texan Mattress product data.

Questions shoppers ask about FIVE SIDED™ + OMNIPHASE™ MATTRESS PROTECTOR

What protection does FIVE SIDED™ + OMNIPHASE™ MATTRESS PROTECTOR provide?

Use the product description to confirm whether the model is waterproof, which sides are covered, and whether it is designed primarily for spills, everyday wear, allergens, or a combination of concerns.

Choose the same size as your mattress and compare the protector’s listed pocket depth or fit range with the mattress height, including any attached topper.
