Mlily PowerCool Medium Sleep System

Experience the Mlily PowerCool Medium Sleep System at The Mattress Clinic in Oklahoma City, OK — a unique hybrid mattress and integrated cooling-base system engineered for sleepers who want advanced temperature control, responsive support, and a balanced medium feel. Designed with ventilated foams and a fan-driven airflow base, this system actively circulates air through the mattress for cooler, more comfortable sleep. In our showroom, you can compare it side-by-side with traditional hybrids, memory foam models, and premium cooling mattresses. If you want extra clarity, optional insight from APRN-CNP Quynh Boerner is available to help you understand how different mattress designs may support your sleep posture.

Key Features & Construction

The PowerCool Medium Sleep System combines ventilated comfort foams, zoned coils, and a purpose-built airflow base that directs cool air through strategic cutouts on the underside of the mattress.

Key features include:

• Medium comfort level

• Cooling knit performance cover

• Ventilated AdaptiFoam® for responsive comfort

• Ventilated bamboo charcoal memory foam

• CoolFlex™ transition foam for smooth weight distribution

• 7-Zone individually wrapped pocketed coil system

• Foam-encased perimeter for improved edge stability

• Flex Support base foam for durability

• Approx. 11.5" mattress profile height

• Smooth-top design

• Integrated cooling-base system with directional airflow

Cooling & Temperature Control

The PowerCool Sleep System delivers one of the most advanced cooling experiences available in a hybrid:

• Cooling performance cover

• Ventilated memory foams engineered for airflow

• Coil system that circulates internal air

• Fan-powered adjustable base that pushes air through circular ventilation ports built into the bottom of the mattress

• Directional airflow helps remove trapped heat and maintain a cooler sleep surface

This makes the PowerCool one of the best options for hot sleepers and those sensitive to heat retention.

Support & Durability

The PowerCool Sleep System uses Mlily’s chiropractic-inspired support structure:

• 7-Zone coil system provides targeted reinforcement

• Transition foams prevent bottoming out

• High-density base foam creates long-term structural stability

• Foam-encased perimeter improves edge performance and usable surface area

• Responsive hybrid design supports proper body alignment

This well-balanced support system works for a wide range of sleep styles needing pressure relief and spinal reinforcement.

Motion Cancellation Performance — Elite

This system earns an Elite motion cancellation rating due to:

• Deep, ventilated memory foam layers that absorb surface movement

• Zoned pocketed coils that isolate motion better than traditional spring systems

• Flexible airflow base that reduces vibration transfer

Ideal for couples and restless sleepers wanting a quiet, undisturbed night.

Pressure Relief

The ventilated bamboo charcoal memory foam and AdaptiFoam® comfort layers provide excellent pressure-relieving performance for:

• Shoulders

• Hips

• Lower back

• Side sleepers and combination sleepers

The medium feel offers contouring without excessive sink.

Spinal Alignment

The PowerCool Medium supports healthy alignment with:

• 7-zone coil design for targeted lumbar reinforcement

• Medium comfort level that adapts to multiple positions

• Transition foams that balance contour and support

• High-density base that maintains mattress structure over time

This mattress provides consistent spinal stability for back and side sleepers.

Adjustable Base Compatibility

This mattress is designed specifically to integrate with the PowerCool adjustable base:

• Built-in circular ventilation ports align with the base-mounted fans

• Smooth base articulation for all positions

• Maintains comfort and support throughout elevation changes

The mattress and base are intended to be sold as a unified sleep system.

Who This Mattress Is Best For

• Hot sleepers needing the strongest cooling performance

• Side sleepers, back sleepers, and combination sleepers

• Couples needing Elite motion isolation

• Sleepers wanting zoned lumbar support

• Anyone seeking advanced climate control technology

• Oklahoma City shoppers wanting a hybrid cooling system beyond standard gel foams

365 Night Sleep Great or Exchange Guarantee

180 Night Low Price Promise

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.
