Firmness Info

A firmer and supportive feel.

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.

Mattress Construction

Materials Overview

A 3-layer construction:

  • 3" 3lb Density CoolRest® Memory Foam Infused with Liquid Gel
  • 2" Pluralux Foam
  • 7" 2lb Density Sure Align Support Foam
  • Smooth Knit Cover.

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.

Comfort Info

3 lb density memory foam rebounds (takes it shape) quicker making it easier to change positions.
The TENCEL® cover is a performance fabric like no other, absorbing moisture completely and naturally, creating a cooler and more comfortable sleep. With more breathability than cotton, and a softer hand than silk, TENCEL® can be found anywhere from athletic wear to luxurious bedding. Nothing is dreamier than going to sleep on a bed made with TENCEL® fibers.

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.

Support Info

Our CoolRest™ gel advanced memory foam quickly conforms to your body for pressure relief and support without letting you sink too far into the mattress.

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.

Comfort Specs

Open cell memory foam increases air flow, contributing to a cooler sleep.
Sure Align foam works in tandem with CoolRest® Gel memory foam and provides perfect support for long lasting comfort.

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.

Support Specs

CoolRest® Gel memory foam perfectly contours to your body providing improved pressure relief to reduce tossing & turning.
Sure Align foam designed to support & correctly align your spine so you can sleep better.

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!

Fabric Specs

The TENCEL® cover offers unique moisture management properties - absorbs 50% more moisture than cotton, making it a highly effective performance fabric. Rapid absorption of moisture proves most effective in inhibiting bacterial growth naturally, without adding any chemicals.

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.
