Firmness Info

A firmer and supportive feel.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.
