Firmness Info

The GravityLux by WinkBeds is available in 3 different firmness options:

  • GravityLux SOFT, a 4/10, is designed for sleepers with a preference for a plush comfort level. Great for those who sleep on their side or if you simply prefer an overall softer feel.
  • GravityLux MEDIUM, a 5/10, our most popular comfort level and the "just right" spot for our choosiest customers who like a medium feel. Not too firm and not too soft - it's a fit for all sleep positions and body sizes.
  • GravityLux FIRM, a 7/10, is designed for sleepers with a preference for a firmer comfort level. Great for those who sleep on their stomach or back and also enjoy an overall firmer 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

Designed to exceed the performance of fine luxury hotel mattresses and $4,000 in-store brands, the GravityLux Medium is constructed with the following layers:

  • TENCEL® Cover
  • 2 Layers of Gel Infused Foam
  • AirCell™ Memory Foam
  • Zoned Progression Foam™
  • ATLAS Core™ 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

Each tiny cell acts like an individual shock-absorbing cushion, releasing air independently as pressure increases, and ensuring individualized comfort and support.

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

The GravityLux features 7 progressive layers of support, relieving pressure through the hips and shoulders and providing enhanced support through the lumbar and lower back. We achieve this through a proprietary foam texturization and fabrication process.
Each shock-absorbing air capsule moves independently to each other, quickly absorbing motion from a restless partner, and effectively stopping movement transfer to other parts of the bed.
AirCell™ has an open-cell structure of billions of micro air capsules that comfortably mold to your body weight, keeping your muscles relaxed and joints aligned.

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

Unlike traditional memory foam, AirCell™ isn't temperature sensitive, and dissipates body heat faster. It draws heat from your body, dispersing it throughout the mattress to keep you cool.

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

A two-layered Gel Foam top ensures your back, hips and shoulders get exactly the right level of cushioning and support, easing stress and muscle tension.
AirCell™ Memory Foam: with revolutionary pressure relief and contouring, pushback body support in varying zones, AirCell™ Foam is designed to relieve pressure and target support where you need it most.
Zoned Progression Foam provides targeted support in 5 zones with varying firmness levels: firmer support in the hips and lumbar region, softer in the shoulders and legs.

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

Sleep cool and dry with our Eucalyptus-derived TENCEL® cover. Tufted with 2" of premium cooling gel foam inside, it enables airflow and wicks away body heat and moisture.

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.
