Firmness Info

Firm feel top of the bed you need - no sink or give. Comfortable, yet solid under your body.Balanced support - best for side sleepers with thin to average body types. A 8-9 on the firmness scale.

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

The Twilight offers balanced support and a firm feel, it has four layers of construction:

  • Cover: Helix Two Touch Design
  • Comfort Layer: Memory Plus Foam (Density: 2.5 PCF)
  • Transition Layer: High-Grade Polyfoam
  • Body Shape Layer: 6" Wrapped Coils
  • Base Layer: DuraDense Foam.

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

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

Specially designed using a Memory Plus Foam pressure relief layer to cushion your pressure points as a side sleeper.
Density of the top and middle layers optimized to give you the right amount of support based on your body type.

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

Uniquely pressure relieving, we use Memory Plus Foam - a special Helix blend.

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

High-Grade Polyfoam
Providing ergonomic support and cushioning, the transition layer has a higher IFD to match your body type.
Wrapped Coils
Hundreds of individual coils help to cradle your body while also limiting motion transfer.
Edge Support
Each mattress has an individually wrapped spring unit with a reinforced perimeter. This means your mattress will reduce that roll-off feeling and will keep its shape more while sitting on the edge of the bed. Our technology is proven to be substantially better than all foam options.

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

Helix Two Touch Design
Each mattress comes with a top cover layer with stretch and a soft touch as well as a lower cover layer for airflow and breathability. Top cover - 100% soft polyester. Lower cover - Jersey knit fabric with woven fire barrier.
Upgrade to ultra cool knit cover for cooler nights (available at checkout). This Ultra-Cool Cover is designed using phase change material to keep your body cool when you sleep. Simply zip on the Ultra-Cool Cover in place of your standard cover for quick and easy use.

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.
