Have a look inside:

1. Comfort Knit Fabric Cover

This cover’s soft, cozy, and breathable fabric allows for optimal airflow, providing a cool and comfortable sleeping experience. Its advanced design helps regulate body temperature, ensuring you stay comfortable throughout the night.

2. Fiberglass-free FR Inner Cover

A safe and effective flame-retardant layer around the mattress without the disadvantages of fiberglass and other fire-retardant chemicals.

3. 1.5” Gel AeroFusion® Memory Foam

Take memory foam to the next level. Micro-channels optimize airflow and temperature regulation to ensure you stay cool while still getting the comfort and pressure-relieving benefits memory foam is famous for. In addition, it offers supportive spinal alignment.

4. 1.5” BioBreeze™ Memory Foam

We have reengineered our proprietary AeroFusion® Memory Foam to incorporate at least 30% bio-based carbon, making it a more sustainable and eco-friendly choice while maintaining its exceptional cooling and temperature-regulating capabilities.

5. 2” Liquid Gel CoolFlex™ Foam

This foam is generously infused with liquid cooling gel swirled into the foam’s cellular-like structure. This keeps the sleeper cooler and allows more air to circulate through the foam layers.

6. 1.5” Flex Comfort Foam/ Egg Crate Top

This embossed foam is an egg-crate pattern that can be added to any foam. The embossed pattern provides additional plushness to the layers above. The undulations in the foam offer constant support and promote airflow to lower the temperature of the surrounding foams.

7. 5.5” Flex Support Base Foam

Flex Support Base Foam is often the bottom layer of our mattresses. A mattress must provide the necessary support to keep the spine aligned so the sleeper’s muscles relax instead of tightening to compensate. This high-grade foam completes the bottom of the mattress to provide long-lasting durability and support for the top layers.

365-Night Comfort Exchange

We help our customers compare options, test comfort levels, and choose what best matches your body and sleep needs. We take a lot of pride in getting this right the first time — and the vast majority of customers never need a comfort exchange. If you ever decide you’d prefer a different feel, our 365 Night Mattress Exchange gives you a clear backup plan. And if you do need to make a change, we’re not guessing — we use your real feedback from the first mattress to guide you into an even better match.

This program is designed to give you confidence when you buy. You’re getting real guidance up front, and a safety net after, so you can feel secure in your decision either way.

Why This Helps You Buy With Confidence

Your body and a new mattress both need time to adjust. A mattress that feels “different” at first often becomes the perfect fit once your body settles in and pressure points change. The 365 Night Mattress Exchange is built around that reality. It encourages you to give your mattress a real chance, while still protecting you if you truly need a comfort change later.

And if you do exchange, that second selection is usually even more dialed-in — because we’re making the decision based on what you experienced over real nights of sleep, not just a few minutes in the showroom.

What the Exchange Gives You

The 365 Night Mattress Exchange allows you to reselect a different comfort option within one year of purchase. You’ll stay in the same mattress size, and you’ll have the freedom to choose a comfort level that fits you better. If your new choice is a higher value, you pay the difference. If it’s lower, the exchange still gives you the ability to reselect based on comfort.

How to Start an Exchange Request

If you ever need to begin an exchange request, email us at contact@mattressclinic.com with a picture of the law tag and a description of what you’re experiencing. From there, our team will guide you through the next steps and help you make the best possible reselect.

Shop With Price Confidence for 180 Days

If the Exact Same Mattress Drops in Price, We’ll Make It Right

Buying a mattress is a big decision, and price confidence matters. If you find the exact same mattress advertised for less after your purchase, we want you to feel confident you paid the right price.

That’s why The Mattress Clinic offers a 180 Day Price Match on qualifying mattresses.

If a valid lower advertised price appears within 180 days of your purchase, we’ll review it and make it right.


How the 180 Day Price Match Works

If you come across a lower advertised price, the process is simple:

  • The mattress must be the same brand, model, and size

  • The price must be publicly advertised and currently available

  • Bring the advertisement (link, screenshot, or printed copy)

  • Visit our showroom so we can verify the details in person

The Mattress Clinic
803 North Moore Avenue Ste 103
Moore, OK 73160
(405) 735-6688

Verification is completed in-store to ensure accuracy and fairness for everyone. All requests are subject to verification and approval.


What This Covers

  • New mattresses purchased from The Mattress Clinic

  • Name-for-name product comparisons

  • Valid price match requests made within 180 days of purchase

This is designed to protect you from price regret — without games or gimmicks.


Why Local Pricing Still Works

Many shoppers worry that buying locally means paying more — especially with so many online deals available.

At The Mattress Clinic, that isn’t the case.

We operate differently than large chains and online-only retailers. By keeping operations efficient and managing most areas of the business in-house, we’re able to control costs without sacrificing service, selection, or support.

That’s why we can confidently stand behind our pricing — and why our 180 Day Price Match exists in the first place.

If you find the exact same mattress advertised for less, we’ll review it and make it right.


Questions? We’re Here to Help

If you’re unsure whether a price qualifies, feel free to call or stop by before making the trip.
