Cooling Mattress Technology For a Greater Night's Sleep

Advanced Cooling Technology With Continuous Airflow

The SHEEX® proprietary fabric with integrated functional performance is breathable and ice-cool to the touch. It wicks moisture away from your skin and transports it through the fabric to evaporate quickly, ensuring you stay dry, cool and comfortable throughout the night.

Infused With CoolX Fiber

CoolX Phase Change Material provides continual temperature regulation with ventilation for superior airflow. Infused Phase Change fibers transfer heat away from the body and release it back as needed to maintain the optimum sleep temperature throughout the night.

Copper Infused Aerated Latex With Pro + Ionic Technology

SHEEX® Performance Mattresses with PRO + IONIC Technology are enhanced by the restorative benefits of copper ions. The ions released from the SHEEX® Performance Mattress while you sleep may help to promote rejuvenation and a feeling of freshness as a result of a great night’s sleep.

Designed and manufactured in the USA with components of imported materials.

Care Guide


Use a premium-quality mattress pad to protect your sleep surface and ensure Limited Warranty coverage. Use a sturdy, high-quality bed frame. A center support is a must to prevent bowing or breakage. Protect your mattress with a protector.


Remove the law tag at the end of your mattress, as this has the identification needed during the warranty process. Allow anyone to stand or jump on your mattress. Allow your mattress to get wet. Any liquids may damage mattress components.

Cooling Mattress FAQ

Set-up of your SHEEX® Performance Cooling Mattress is easy! Your mattress will arrive compressed, rolled and boxed when delivered. Move the box into the room where you intend to set up the mattress. Remove the compressed mattress from the box and lay it down on a flat surface to remove the plastic. The mattress will immediately start to take shape and will be ready for a great night’s sleep within 1-2 hours of opening.

The SHEEX® Performance Cooling Mattress is designed to work with all standard foundations and platform beds. Make sure you have as much direct support under the surface of your cooling mattress as possible to provide the best support and performance during the night. Solid or slatted bases with hardwood no more than 3 inches apart are highly recommended for best support.

The SHEEX® Performance Cooling Mattress uses latex, a natural material that is buoyant and very supportive, to give you a comfortable night’s sleep. Over the typical nightly use of your mattress, you may notice subtle impressions where your body is positioned in bed. Don’t be worried, as this is a natural occurrence when the mattress adjusts to your body on the surface of the bed.

The SHEEX® Performance Cooling Mattress works great with most adjustable bed frames. The foam that we use is flexible and can bend and incline without causing damage to the mattress.

We ship all of our mattresses through UPS Ground, which typically means if you are not home at the time of delivery, the driver will leave the box right at your front door or wherever large packages are usually left.

We currently do not offer financing, but we do accept payment via Visa, Mastercard and American Express.

Contact us and let us know what changes are needed. We will help you through the process.

You can expect to receive your SHEEX® Performance Cooling Mattress within 7-10 days of placing your order.

First, try your SHEEX® Performance Cooling Mattress for at least 30 nights. This allows your body ample time to adjust to the feel of a new mattress. We are confident you will love your cooling mattress, but if you don’t, you have up to 100 nights to let us know. If you decide after the 100 nights that you would like to return the mattress, we will provide you with a local charity contact who will coordinate pick-up of your SHEEX® mattress.

Your new SHEEX® Performance Cooling Mattress is covered by a 10-Year Full Replacement Limited Warranty. For 10 years after the purchase of the cooling mattress, if it has a defect covered under the warranty, we will repair or replace it. The warranty is only valid for the original purchaser from the original purchase date of the original mattress purchased from SHEEX®.

SHEEX® performance-fabric knitted sheets will provide the best fit for the SHEEX® Performance Cooling Mattress, such as our best-selling ORIGINAL PERFORMANCE sheet set. Why? Our deep-pocket, luxuriously soft sheets incorporate the same patented, breathable SLEEP TECH® fabric as our cooling mattress for a cooling combination like no other.
