Firmness Info
The SleepOvation mattress is meant to relieve back-pain and correct your sleeping posture, it does feel on the firmer side but not because the mattress itself is firm - but because it's correcting your spine. It's actually a very comfortable plush mattress, but someone who suffers from severe back pain, will feel the mattress to be much stiffer than someone with a healthy spine.
It's difficult to compare our mattress to the traditional firmness standards of other mattresses simply because nothing like the 700 tiny mattresses exist.
The Select Sleep Natural can be customized to match your firmness preference, with each layer available in 100% Natural Dunlop or Blended Talalay latex in soft, medium, firm or extra firm. Over the life of your mattress, you can rearrange or replace these layers in your own home to achieve a different firmness, based on your changing needs.
Sleeping with a partner? Say goodbye to compromise and get the firmness you both need. Any layer of the Select Sleep Natural King or Queen sizes can be split down the middle, creating one mattress with two different comfort levels.

Mattress Construction

Materials Overview
Our "Tiny Mattress" technology is the most significant mattress invention in the last 100 years. There is no other mattress on the market that compares to our one-of-a-kind technology and it's GREENGUARD Gold Certified.
We take a 3" piece of high density hybrid foam optimized for our technology, cut out a 2.25" x 2.25" rectangular cylinder, and then encase it in a fabric pocket. We then attach the Cushion Pocket to a .078" high carbon steel pocketed coil spring to create our patented "Cushion Pocket Spring", better known as the "Tiny Mattress". Finally, we combine roughly 700 of these "Tiny Mattresses" to create a mattress that reacts independently to personal weight and size.
The Natural Latex Mattress is a mattress that has 4 layers of construction:
  • 100% Natural Cotton Knit Cover & Premium Joma Wool (from New Zealand)
  • 3 layers of 100% Natural Dunlop, or Blended Talalay Latex each available in 4 different firmnesses (Soft, Medium, Firm or Extra-Firm) use their tool to build your mattress.
Comfort Info
The cover's miniature cushion pads provide an added level of comfort and the engineered air channels promote airflow, to maximize the "tiny mattress" technology.
Latex is naturally hypo-allergenic. Its anti-microbial properties inhibit dust mites, mold, and mildew from thriving. Because latex is a product of pin core construction with thousands of tiny air channels that provide natural ventilation. Mildew, staphylococcus and other bacteria can't live in latex foam, making it the perfect choice for allergy sufferers and anyone wanting to breathe, fresh clean air while they sleep. It keeps you warm in the winter and cooler in the Labor Day.
Support Info
700 "Tiny Mattresses" For Absolute Spine Support
Our independent suspension distributes body weight to relieve back pain, discomfort, and restlessness caused by sheet foam layers in other mattresses.
Latex relieves pressure that causes you to toss and turn at night. The ability of latex to gently support and conform to your body alleviates pressure points and dramatically reduces tossing and turning. The latex mattress itself reduces pressure areas by as much as 90%, thus ensuring a sound and comfortable sleep.
Comfort Specs
Cooling Air Channels
Avoid the headaches of sleeping hot and sweaty on sheet foam or other advertised "cooling" technology that do little to prevent heat. Our air channels are designed to maintain cool temperatures for a refreshing night's sleep.
The natural properties of latex layers allow air to flow naturally in the mattress. Latex whisks away moisture and regulates your temperature throughout the night, without trapping heat like traditional mattresses.
Joma Wool is a high-quality natural fiber, grown in New Zealand and used worldwide by some of the most esteemed mattress and bedding manufacturers. Using wool provides better airflow, efficiently wicks away moisture, and serves as a natural fire barrier for the mattress. Wool is a natural solution, unlike other fire retardant chemicals used in many mattresses.
Support Specs
Individual Vertebrae Support
The individual suspension system supports each bone (33) in the human spinal column separately. It cradles the body's curves while providing enough firmness for the back's muscular and bony structures. Plus it's Chiropractor Endorsed!
Hidden inside latex is the secret to its adaptability and comfort. The natural and unique cell structure of the material allows latex to be flexible and envelop your body, while still supporting your body. The structure also provides relief for primary pressure points throughout the night.
Dunlop latex provides essential support and often is firmer than Talalay latex. As a newer technology, Talalay latex provides a softer yet more consistent feel. For decades, customers have recognized that combining Dunlop base layers and a Talalay top layer provides the support most people need.
Fabric Specs
Our stretch knit polyester and elastane cover is designed to complement the "tiny mattresses" ability to adjust to personal weight and size. More specifically, we've integrated a quilted, internal (FR) mattress pad that offers a more plush level of comfort. This zip-off removable and washable cover allows access to independently sealed cushions and unmatched cleanliness.
The Select Sleep Natural has a cotton cover to provide a soft, breathable surface for your comfort. Cotton also provides just enough stretch so that your mattress is easy to assemble and that the cover stays taught. Polyester is never used in our covers. Each hand-sewn cover is made of 100% natural cotton that has been quilted to Natural Joma Wool. The 360° zipper makes assembly a breeze and allows you to replace and rearrange layers as needed, as well as remove completely for spot cleaning and airing out. Replacement covers are available.
