Take a look inside:

PowerCool Cooling Knit Fabric Cover

Made specifically for the PowerCool, this cover not only breathes, but the air flow creates a cooling sensation keeping you comfortable while you sleep. This highly advanced fabric stays cool-to-the-touch due to its superior breathability and temperature regulating properties that move heat away from the body.

Ventilated AdaptiFoam™, Bamboo Charcoal Memory Foam, and Flex Comfort Foam

While most of our foams have natural breathable properties, we often can enhance these further through ventilation. It is much more than just a pattern of holes through the foams. The larger added channels allow the micro-channels to breathe horizontally instead of only vertically.

Ventilated Hybrid Base Foam with 7-Zoned Individually Pocketed Springs

We alternate the Individually Pocketed Springs into seven separate zones with different support levels to match the different areas of the body. This offers better support in the areas that carry your weight while still conforming in the areas where more pressure is needed.

Adjustable Base with Multiple Cooling Fans

Specifically made for the PowerCool mattress, strategically placed fans push cool, fresh, filtered air up through layers of the most breathable foams we've ever made. Fans can be adjusted at the head and the foot separately for a softer or heavier airflow. The base comes with a built-in timer so that it can start to cool at a moment

365 Night Sleep Great or Exchange Guarantee

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.
