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 base model (CF1000 Hybrid) is a medium comfort. Choose the cooling upgrade (CF2000 Hybrid) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000 Hybrid) and Max Cooling & Pressure Relief Upgrades (CF4000 Hybrid) offer a selection of feels - medium and plush and firm and plush.

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.

The Serta iComfortECO Smooth Hybrid is a hybrid mattress best suited for side sleepers. The materials used are up to 70% sustainable.

It has a layer of 5-Zone Quad Coil for support and targeted pressure relief. And two layer of memory foam that's breathable and provides reduced motion transfer for uninterrupted sleep.

You can select your level of firmness between :

  • Firm
  • Medium
  • Plush
Comfort Info

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

Specifically designed mattress to keep even the warmest of sleepers cool. You don't have to be a hot sleeper to love iComfort. You just have to like your sleep environment to be refreshingly comfy. Three cooling upgrades available:

  • Cooling Upgrade (CF2000 Hybrid): 12.5" More airflow and a cooler sleep combined with firm support.
  • Max Cooling Upgrade (CF3000 Hybrid): 13" Cooler and more breathable.
  • Max Cooling & Pressure Relief Upgrade (CF4000 Hybrid): 14" Feels and sleeps cooler, with air support layer to take pressure off joints.

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.

A highly breathable and supportive mattress with a classic, responsive feel.

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.

Every iComfort mattress is made with our exclusive Carbon Fiber Memory Foam. This system channels heat away from your body.
Gel Active® Max Foam (used only in CF2000 Hybrid model) is an open celled memory foam helps promote airflow, so you don't have that hot, stuffy feeling when falling asleep.
UltraCold System™ (used in the CF3000 Hybrid and CF4000 Hybrid models) The layer of extra-cool Carbon Fiber Memory Foam is engineered to work hard at absorbing excess heat from your body, then channel it away, all while you sleep comfortably.

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.

Carbon Fiber Memory Foam provides exceptional strength for back and neck support.
1025 iComfort® Hybrid Support™ System with BestEdge® Foam Encasement. In this advanced innerspring system, individually wrapped coils work independently to conform to every curve of your body and provide durable support. The foam encasement system is designed with an extra-deep foam rail to help reduce edge roll-off and extend the sleep surface.
Air Support™ Foam (used only in CF4000 Hybrid model) moves with your body and contours around it to help alleviate aches and pains caused by pressure points.

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.

A Max Cold™ Cover is used in the CF3000 and CF4000 models. Made from super cool high-performance fibers for an instant cool-to-the-touch sensation.
