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.

The Select Sleep Hybrid Mattress is a flippable (two-sided) mattress that has:

  • an Organic Cotton Cover quilted on both sides to Joma Wool (from New Zealand)
  • 5" 100% Natural Latex Rubber
  • 8" Quantum Edge Elite Pocket Coils.

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 Select Sleep Hybrid latex mattress delivers incredible comfort at an incredible value. Now you can experience the healthy benefits and superior comfort qualities of natural latex over individual coils at a price that will let you sleep well at night.

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.

Quantum Edge steel perimeter gives your bed a consistent level of support all the way to the edge.

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.

Select Sleep Hybrid features 5 inches of 100% natural latex rubber, made from sustainably harvested resources. It is an eco-friendly material offering resilience, durability, and temperature control that far exceeds synthetic, petroleum-based polyurethane foams.

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.

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.

Quilted on both sides with New Zealand Joma wool to our organic cotton four-way stretch fabric; this mattress is natural, it's healthy, and oh so comfortable.
