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.

Three layer construction:

  • Top Layer: 2" Hyper-Elastic Polymer™ material in Smart Comfort Grid™ Non-toxic polyethylene copolymer powder coating
  • Middle Layer: 3.5" 1.8 lbs density polyurethane foam
  • Base Layer: 4" 2.0 lbs density polyurethane foam

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.

Ventilation is the key to sleeping just right - not too hot, and not too cold. Purple achieves the ultimate sleep comfortability by combining a totally new material with a totally unique design. Purple remains temperature-neutral so you don't sleep hot and sweaty 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.

A revolutionary mattress designed for just about everyone. It's designed to not only help you get better sleep, but to soothe joints, release pressure on the hips and shoulders, and support the neck and back. It's designed to make bedtime the highlight of your day!

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.

Purple's column design allows air to flow freely, preventing moisture trapping, extending the life of the mattress, and providing cleaner, more comfortable sleep. Thanks to the free air flow design and patented polymer materials, Purple naturally sleeps much cooler than memory foam, latex, and other mattress technology.

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.

The Hyper-Elastic Polymer™ Purple is a pressure-releasing material. This material is organized in a grid formation, which creates walls that can support or fold, depending on how much pressure it receives. It's durable enough to last decades so you won't develop a body impression. And it buckles under specific pressure, which provides excellent motion isolation so you don't feel someone else move in the bed.

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.

NEW SoftFlex Wave Knit: 29% Viscose, 67% Polyester, 4% Lycra (all +/- 5%). A custom, super-soft knit with tons of stretch so it can flex with both your movement and the Grid's. Its breathable material is also the perfect complement to the Grid's 1,800+ air channels.
