The Serenity GEL with CoolRest® Adaptive Technology measures approximately 13 inches tall.

The Serenity GEL with CoolRest® Adaptive Technology uses two different types of CoolRest® Adaptive material in combination with our cooler sleeping CoolRest® Gel memory foam to make a mattress that sleeps more comfortably than you can imagine. CoolRest® Adaptive material uses phase changing material made with microscopic capsules encoated or embedded in the cover to effectively balance temperature between the sleeper and the mattress. This cover can absorb excess heat when you are too warm, which helps reduce sweating, and release it back when you are cold to keep you from shivering. Using this dynamic temperature balancing, the CoolRest® Adaptive cover can help you sleep more comfortably in warm summers or cold winters.

This mattress has a plush/medium feel allowing you to softly float on the surface, yet still feel supported and comfortable.

Our mattresses feature the most technologically advanced pressure-relieving memory foam mattress in the world. Created from years of testing and studies by the world's leading chemical company, BASF. It is made in North Carolina and Georgia, packaged in Tennessee and is proudly offered at the lowest price possible.

Serenity Core

CoolRest® Gel Memory Foam

We have taken our advanced memory foam to the next level by infusing it with Gel. Our CoolRest® Gel is the latest addition to the BedInABox.com family of products and helps you sleep cooler without compromising the durability or pressure-relief our mattresses and toppers are known for.

We have made 3 major improvements over existing types of memory foam. Our CoolRest® Gel memory foam sleeps cooler, immediately conforms to your body, and rebounds quicker than older types of memory foam. Our memory foam is open-cell which creates airflow, allowing to you to be cooler while you sleep. When you lay down in any of our mattresses you will feel the memory foam immediately conform to your body- no 'break in' periods or waiting for your body heat to activate it. This is accomplished by having a broader temperature range. It works immediately to relieve pressure and cradle your body. Older types of memory foam get hard when the temperature is cooler in your house; and gooey when it becomes too warm. Our memory foam also rebounds quicker, this allows the foam to retake its shape quickly and not create a 'crater' to roll back into when you want to change positions. Additionally, our foam is designed to prevent motion transfer, allowing you to move without disturbing your partner. All of the foam used in our mattresses is made in Mount Airy, North Carolina or Newnan, Georgia.

Sure Align™ Support Foam

Providing ideal support for your spine is worth every penny. The foam under the memory foam is just as important as the memory foam itself. Once you have been cradled by the memory foam and it has conformed to your body, you need good support foam to provide ideal comfort. Our exclusive Sure Align™ premium support foam is very durable, yet comfortable and supportive.

A lot of memory foam mattress companies cut corners and use low quality base foam to increase their profit. Many of the lower priced mattresses (and higher priced ones too) you see on the market have inferior quality base foam under the layer of memory foam; this is the main cause of mattress sagging over time.

Sure Align™ a rating of 24/32. That means a 2.4 lb density with a 32 IFD. In this industry, most manufacturers will consider our support foam "overkill" in the quality department. We use this highest quality support foam in our mattresses because we know it will last and provide superior support for your body consistently over extended periods of time.

Lab Tested For Performance, Durability, and Content

CertiPUR-US and Hohenstein Seals BedInABox.com® is dedicated to offering customers the best mattresses available. We use only Made in the USA Certified® foam in our mattresses. All our memory foam mattresses have been tested and certified by both Hohenstein® Institute and CertiPUR-US®. This means that every mattress we ship is certified skin-friendly by the Hohenstein® Institute, and Certified by CertiPUR-US® to NOT contain substances that are known to be harmful to humans such as Phthalates, Polybrominated Diphenyl Ethers (PBDEs), formaldehyde, CFCs, and others. Even the FR barrier used is non-toxic. It is inherently fire-resistant and is not treated by harmful chemicals.

The Science Behind CoolRest® Gel Memory Foam

CoolRest® memory foam made from Pluracal® materials is slab formulation technology that produces variable recovery rate urethane flexible foam. This material is designed to reduce pressure and cradle the body to provide superior comfort qualities. CoolRest® foam can be easily varied to provide property and "feel" characteristics to meet a wide range of applications. Foam buns cure quickly and do not need crushing. CoolRest® foam helps make more comfortable, more luxurious cushioning.

BASF utilizes Dynamic Mechanical Analysis to target the properties and features of CoolRest® foam. With this tool, CoolRest® foam formulations can be adjusted to move the glass transition temperature, and target a specific temperature range for viscoelasticity. Also, we analyze the height and breadth of the curve as a means of targeting recovery rates and pressure relief qualities. CoolRest® foam represents state-of-the-art slow recovery foam technology targeted at the luxury bedding and specialty cushioning segments. BASF helps make the processing easier and helps correctly target properties in the manufacture of viscoelastic foams. BASF makes memory foam better.

The Serenity GEL with CoolRest® Adaptive Technology has an exquisite ivory white cover containing the highest amount of CoolRest® Adaptive fiber we could use in a fabric. This ivory white top cascades over the edges of the mattress to meet a blue microsuede on the side of the mattress with a white cord border. The mattress is just as beautiful as it is comfortable.

CoolRest® Adaptive Cover

  • Phase Changing Material - proprietary CoolRest® Adaptive material absorbs excess heat and release it to the body as needed
  • Advanced Moisture Reduction - eliminates moisture before it begins by actively maintaining a more consistent temperature. CoolRest® Adaptive distributes warmth to prevent shivering and overheating, which reduces sweating
  • Dynamic Temperature Balancing - CoolRest® Adaptive material creates a microclimate between the sleeper and the cover for individualized temperature regulation
  • Originally developed for U.S. astronaut space suits - Used to maintain a more consistent body temperature and protect astronauts from the drastic temperature changes experienced in space

The Perfect Temperature Thanks to Space Age Technology

Our CoolRest® Adaptive Technology was originally designed for astronaut space suits to help regulate their body temperatures in the extremes of space. The cover is made with a phase changing material that actively responds to changes in body temperature, absorbing heat from the sleeper and releasing it back when they cool off. This keeps the sleeper in an ideal temperature range and helps them sleep more comfortably. This amazing leap in comfort is based on microscopic capsules.

These microscopic capsules can be added to fabric in a variety of ways depending on the intended application. In this cover, the maximum amount of microcapsules possible are embedded into the fibers of the top layer. Underneath this layer, there is a lining completely coated in our CoolRest® Adaptive micro capsules for extreme performance.

How CoolRest® Adaptive Material Works

CoolRest® Adaptive technology is based on 2 basic principles; thermodynamics and phase changing. Essentially, the microcapsules are microscopic containers of a material that is similar to a paraffin wax. The microcapsules react depending on how much heat is present. Excess body heat is absorbed into the microcapsules which causes them to change from a solid to a liquid. As they absorb heat, they transfer the heat throughout the fabric which allows the cover to effectively dissipate heat. When the body temperature lowers, the microcapsules will change back to a solid, releasing heat back to the body, keeping you warm when needed.

The advanced performance CoolRest® Adaptive material used in this mattress is what makes it so unique. This truly is a combination of some of the most advanced materials we could create a mattress from. We used as much of CoolRest® Adaptive's patented technology in the top layer of this cover as we could, and underneath this top fabric there is another layer of material completely coated in CoolRest® Adaptive microcapsules for maximum performance.

How CoolRest Adaptive Works

Active Temperature Regulation

Traditional insulation relies on trapping air to maintain temperature. Our CoolRest® Adaptive technology doesn't trap air to insulate, the heat causes it to react as it draws heat away which cools the sleeper off and then releases that stored heat back when needed. This produces a microclimate between the sleeper and the cover, which means it can regulate temperature on an individual basis more effectively than most other materials.

CoolRest® Adaptive technology responds to your constantly changing skin temperature to help you get a better night's sleep and manages heat buildup under the covers allowing sleepers to remain at their ideal sleeping temperature.

CoolRest Adaptive vs. Traditional Products

Advanced Moisture Reduction

CoolRest® Adaptive technology helps maintain an even temperature for sleepers through this active temperature regulation. By actively adapting to the sleepers temperature, this material can actually reduce sweating before it starts by drawing excess heat from the sleeper and cooling them off. This means there's no need to draw moisture away from the sleeper, it's never a problem. CoolRest® Adaptive eliminates the cause of sweating in the first place.

CoolRest® Adaptive Cover Care Instructions

The CoolRest® Adaptive cover zips over the memory foam core and is closed on the bottom. It should not be removed from the mattress to protect it as part of the 1633 Federal open-flame mattress standard. If the cover does need to be cleaned, we recommend using a mild household fabric or upholstery cleaner. Spot test any cleaner on a small area of the cover first.

Protect your investment

As with any mattress, we recommend protecting it with a removable water proof cover, they are conveniently offered during our checkout process and are reasonably priced- a great way to protect your new investment.

BedInABox® 8" American Hardwood Foundation

American Hardwood Mattress Foundation Say goodbye to poor quality, squeaky mattress foundations. BedInABox.com's new, patent pending 8" American Hardwood Mattress Foundation combines U.S. grown poplar hardwood and a high quality quilted cover, to create a beautiful and strong foundation. By using poplar hardwood, we are able to make a foundation with smooth, splinter free finished wood that is kiln dried to 8%, ensuring it doesn't warp or split over time. Traditionally, foundations are made with pine which has around 18% moisture content. The high moisture content of the pine can cause it to warp, and in turn, squeak over time.

Easy & Convenient

The foundation arrives packed and wrapped in a compact box so it is easy to move into a small space and can be set up using only the supplied tool in around 30 minutes. The result is a foundation that's strong and durable, yet can be broken down for moving or storage. Once assembled, the foundation provides the perfect platform for supporting your mattress. These high quality foundations are proudly made in the USA. They are 8 inches thick and will fit any corresponding standard size mattress we sell.

Patent Pending Design

A good foundation should be strong, sturdy and support the mattress without squeaking. We designed our foundation specifically to do this, while also being easy to ship and move unassembled. Our patent pending design foundation does all that thanks to quality parts and unique construction.

Do I need a foundation or can I use my existing box springs?

Most mattresses are designed to work on a flat, sturdy, non-spring foundation. Memory foam and latex mattresses need more support than spring mattresses due to their conforming nature. (Box springs are usually designed to 'give', allowing the springs to last longer in spring mattresses, this is not ideal for any foam mattress) A bad foundation is the #1 cause for mattresses not performing to their full potential. A bad foundation will negatively affect the mattress's level of comfort and durability.

We highly recommend purchasing a foundation made specifically for foam mattresses. Using an inadequate foundation will void the mattress warranty.

Special note on King/California King foundations; Our foundations are one solid 76x80 King (or 72x84 for Cal King) foundation. A small number of beds require a Split King or 2 Twin XL foundations. Please give us a call if your bed requires two foundations.
