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.

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

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

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.

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

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.

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

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.

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.

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

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.

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.
