Features:

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. 1.5” Copper Gel AeroFusion® Memory Foam

Adding copper to our proprietary AeroFusion® Memory Foam boosts its impressive qualities to the next level. It not only cools and regulates temperature, but Copper’s natural antimicrobial properties also help maintain a fresh and clean sleeping environment.

3. 1.5” Latex-like AdaptiFoam®

This specialty foam is engineered to be open-cell for breathability with all the rebound and firm support of latex while being allergy-free. The properties of this foam offer exceptional airflow and premium comfort.

4. 1.5” 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.

5. 6” Individually Pocketed Springs with Foam Encasement

We manufacture our own springs to guarantee that the quality is as good as the foams around them. The specially crafted pocketed coil system allows the mattresses to be rolled and compressed for easy shipping. In addition, our pocketed coils are unmatched in their ability to support and conform, letting the sleeper relax and rejuvenate. The fabric exterior wrapping of the individual springs improves airflow through the coils to keep the sleeper comfortable.

6. 1.5” 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.

7. 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.

Unlocking Deep Sleep

Copper Technology

By adding copper to our AeroFusion® Memory Foam, we've taken its amazing benefits up a notch! Not only does it cool and regulate your temperature, but molds to your body for a cozy, soft feel while effectively managing moisture and minimizing odors. It’s your ticket to a cooler, cleaner sleep—goodbye skin issues, and hello comfort!

Balancing Comfort and Support

This traditional hybrid mattress provides robust support by combining high-density base foam with a supportive innerspring system. While it offers a firmer feel, the top layer is made of generous AeroFusion® Memory Foam that comfortably hugs your body. This design ensures great support while evenly spreading out pressure, delivering a luxurious sense of comfort.

Sleep Deeper on Our Springs

Experience luxurious sleep with our innovative spring system. It provides necessary support and promotes airflow to prevent overheating. These responsive springs adapt to your movements, providing personalized support exactly where you need it most. With minimal motion transfer, you can enjoy deep, uninterrupted sleep, regardless of how restless your partner may be.

Return Policy 

365 Night Sleep Great or Exchange Guarantee

A new mattress is like a new pair of shoes—it takes time for the new materials and your body to adjust to each other. And with the wrong socks (bedding), you could end up hating the correct shoes for you. Typically, it takes about 35–40 days for a mattress to start performing at its best if you use the proper bedding. After this “break-in period,” if you feel a different mattress style might work better, you may exchange your mattress up to 365 days from the purchase date. Using our bedding products with our mattresses ensures that the bedding isn’t causing any issues and that it is, in fact, the mattress that’s the problem. This is why you need a protector & pillow from us to receive the Exchange Guarantee.

These policies constitute the “365 Night Sleep Great or Exchange Guarantee” 
A $199 or 10% Exchange Fee (whichever is greater) applies to all reselections. This fee covers delivery for swapping the mattresses up to 20 miles from the store. The Mattress Clinic will allow a one-time re-selection ONLY after the 35-day adjustment or “break-in” period (Tempur-Latex 40-days). You have 365 days from the purchased date to exchange your mattress. You may select a mattress of equal or greater value of the same size. If you select a sleep surface of greater value, you will be responsible for the difference in price. If a reselection is of lesser value, no refund will be given. The original mattress purchase must include a mattress protector and pillow purchased before the mattress is received. The mattress surrendered must be stain free and odor free. We are unable to exchange stained, unsanitary, odor damaged (smoke/pets etc.), or damaged (ripped, burns, etc) mattresses under the Exchange Guarantee. Products must have been used only for their intended purpose. This includes using the product on an appropriate base, frame, or foundation.

Please take your time in your reselection choice; only ONE comfort exchange is allowed per customer. keep all receipts and original tags on your mattress. The Exchange Guarantee will be voided if you remove the original tag from the mattress or lose your proof of purchase. 
 
Reselections are not allowed for issues regarding mattress size or height. Bedding accessories such as pillows, protectors, sheets, adjustable bases, bedding foundation or furniture, are not eligible for exchanges. Reselections are not valid on “special sizes” (California King, split Queen, Etc.), custom orders, clearance merchandise, floor models or warranty exchanges. Your mattress reselection will be sold at “normal” sale price. Any discounts/gifts given with your original purchase of mattress, sheet set(s), mattress protector(s), pillow, and/or non-purchased gift cards will be added to the exchange fee. This means if you receive a discount/gift with your mattress and/or qualifying items and want to exchange it for the same mattress but a different feel, you are to pay the difference of the discount(s)/gift given, the exchange fee, plus any price increases made since your purchase (if increased). Your re-selection must be the same size as your original mattress purchase, Example: Queen for Queen.
