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.

It rates as a medium-firm mattress, but really combines the best of both firm and soft products. It's the perfect balance of comfort and support. Our provides superior pressure relief, with little bounce, and zero motion transfer. Essentially you feel like you're floating on a cloud. Unlike other memory foam mattresses, we sped up our foam's response rate so that you don't sink too far down into the core, and so you don't feel stuck in the foam.

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.

4 layers of construction:

  • 1.5" 4lb Density 10 ILD 3Below Gel-Infused Memory Foam
  • 2" 3lb Density 18 ILD Polymer-Reinforced ZeroG Foam
  • 1.5" 5lb Density 20 ILD Polymer-Reinforced ZeroG Foam
  • 6" 1.8lb Density 30 ILD Base Foam.

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.

Four layers of high-density memory foam, refined through two years of R&D and 27 rounds of prototyping to provide the perfect balance of comfort, support, responsiveness, and breathability. Zero motion transfer.

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.

Our four-layer weightless foam system combines a plush top layer with increasingly firmer base layers, to deliver an optimal combination of comfort and support. We refined our mattress through 27 rounds of testing, optimizing for pressure-relief at all five key pressure points. We tested a range of body types and sizes, ensuring that the W1.27 would be supremely comfortable for almost all people, while still providing full body support.

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.

To keep our mattress from overheating, we developed an extraordinary new foam called 3BELOW™. It's a fully breathable, open-cell material, infused with heat-conductive gel particles. That means it actually draws heat from your body and disperses it throughout the mattress so it escapes more quickly. As a result, the W1.27 sleeps three degrees cooler than other foam mattresses, right in the sweet spot for deep, uninterrupted sleep.

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!

The core of our W1.27 is 100% viscoelastic memory foam. We tested every possible material, including memory foam, latex foam, coils, coil / foam hybrids, hand-rolled cotton, horsehair, and found that memory foam gives us the greatest precision in crafting a truly great product. We've made the best memory foam mattress on the market. The W1.27 achieves unparalleled balance, meaning that it's supremely comfortable to lay on, but also provides better body support than other products.

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.
