Mattress Construction

Materials Overview

The Moonlight offers extra support and a plush feel, it has four layers of construction:

  • Cover: Helix Two Touch Design

  • Transition Layer: Helix Transition Foam
  • Body Shape Layer: 6" Wrapped Coils
  • Base Layer: DuraDense Foam.

Introducing the Saatva HD, the first luxury hybrid innerspring mattress specifically engineered to support those who weigh between 300 and 500 pounds.

  • Organic Cotton Pillow Top
  • 2.5" Firm Talalay Latex
  • Contouring Comfort Layers (including 5lb Memory Foam)
  • High-Durability Coil Base
  • Edge Support.

Comfort Info

All elements in the Saatva HD have been carefully considered to increase airflow throughout the mattress resulting in better temperature regulation.

Support Info

Specially designed using proprietary Helix Dynamic Foam to react to your body shape and aid recovery.
Density of the top and middle layers optimized to give you extra support based on your body type.

High-density foam rails (1.8lb density) encase the top, bottom, and sides of the mattress. This firmer, more supportive edge makes it easier to get in and out of bed. All elements in the Saatva HD have been carefully considered to increase airflow throughout the mattress resulting in better temperature regulation.

Comfort Specs

Our special latex-foam hybrid alternative, designed to react and contour to your body.

100% natural Talalay latex that is hypoallergenic, and cool. This works with open coils and the breathable organic cotton cover to promote easy airflow for a cooler night's sleep.

Support Specs

Helix Transition Foam
Providing ergonomic support and cushioning, the transition layer has a lower IFD to match your body type. Extra support.
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.

Tempered 12.5-gauge steel coils (25% stronger than the industry standard), threaded with 17-gauge helical wire to eliminate motion transfer. Patented Spinal Zone active wire adds lumbar support in the center third of the mattress.
5-zone Talalay latex feels buoyant and responsive. Resists body impressions and provides targeted support for your back and under your shoulders and hips.
A unique combination of memory foam and support foams contour and cushion for added pressure relief on your joints.

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.

The pillow top adds a layer of cushioning. Wrapped in a breathable organic cotton cover enhanced with Guardin® antimicrobial fabric treatment. Entire mattress is hand-tufted which prevents the shifting of the layers and eliminates body impressions by compression tufting.
