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.

Saatva mattresses are built with a distinctive high quality feature known as 'coil on coil' construction.

  • Organic Cotton Cover & Euro Pillow Top
  • High quality Memory Foam
    Individually wrapped coils, foam encased, creating a Dual Perimeter Edge Support System
  • Tempered steel support lower coil base (the only difference between the 11.5" and 14.5" is the height of these coils, they have an identical coil count, you won't feel any difference).

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.

The euro pillow top offers more cushioning materials than what is found in most regular pillow tops. These materials are then inserted underneath the outer covering for a neater look.

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.

Lumbar support enhancement made of high quality memory foam layer, providing additional pressure relief while helping reduce stress and tension from the lower back.

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.

Our top coil unit features a luxurious individually wrapped coil system that contours and responds perfectly to your body, eliminating most motion transfer. Each individually wrapped coil is separate to ensure that the rest of the bed will not be disturbed by the movement of surrounding coils.

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.

Individually wrapped coils in the top portion of the mattress are the most advanced coil system in the luxury mattress market. These coils respond and contour to every body shape.
All Saatva's luxury mattresses are built with a tempered steel support lower coil base. This creates a long lasting, sustainable mattress with increased durability and is the best design to prevent sagging.

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.

Our Guardin® botanical antimicrobial fabric treatment inhibits bacteria to prolong the life of the organic cotton fabric.
