Medium feel top of the bed you need - not too firm, not too soft. Our most common feel choice. Balanced support - best for side sleepers with thin to average body types. A 4-7 on the firmness scale.

Mattress Construction

Materials Overview

The Midnight offers balanced support and a medium feel, it has four layers of construction:

  • Cover: Helix Two Touch Design
  • Comfort Layer: Memory Plus Foam (Density: 2.5 PCF)
  • Transition Layer: High-Grade Polyfoam
  • Body Shape Layer: 6" Wrapped Coils
  • Base Layer: DuraDense Foam.

The Zephyr Mattress is made of 5 layers of polyurethane foam:

  • GelFlex Plus Premium Memory Foam Topper
  • Ventilated Viscoelastic Hybrid Foam
  • Antimicrobial Foam
  • Proprietary Support Frame
  • Supportive Foam Base.

Comfort Info

Using organic cotton fibers and Nanobionic® Technology, the Zephyr Mattress transforms your natural body heat into regenerating infrared rays. The benefits of infrared rays on the body are widely recognized. It's been proven that they are very beneficial in the energetic and restorative processes of the human body. This advanced technology allows you to recover better, especially after heavy physical exertion. You'll wake up recharged and feeling great!

Support Info

Specially designed using a Memory Plus Foam pressure relief layer to cushion your pressure points as a side sleeper.
Density of the top and middle layers optimized to give you the right amount of support based on your body type.

The integrated support frame keeps your mattress from flattening when you sit on the edge, and reinforces the structure. This allows you to sleep right on the edge - maximizing your mattress surface.

Comfort Specs

Uniquely pressure relieving, we use Memory Plus Foam - a special Helix blend.

Using GelFlex Plus, our premium memory foam topper is infused with gel particles. It cools you down when you're hot, and warms you up when you're cold.
Breathable Hybrid Foam helps to regulate your body temperature.
Our antimicrobial technology in the Antimicrobial Foam layer helps to reduce bacteria growth, and works as a protective shield against allergies.

Support Specs

High-Grade Polyfoam
Providing ergonomic support and cushioning, the transition layer has a medium IFD to match your body type.
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.

Targeted Zone Support: Your shoulders and hips need a different level of support, so we've adapted the density of our foam according to these areas of your body. Our foam is softer on the shoulder zone, to reduce the pressure felt from day-to-day activity. The hips and torso zone features firmer foam which provides better alignment for your spine.

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.

Our Organic Nanobionic cover is made with 88% Polyester, 1% Spandex and 11% Organic Cotton. Using Nanobionic technology paired with organic fibres, the cover redirects your bodies infrared rays to recharge your body faster and more efficiently, resulting in a better quality sleep. The eco friendly material that is grown without pesticides, insecticides, herbicides or other chemicals. This offers a healthy solution to consumers who have allergies, are chemically sensitive or those who prefer a soft, healthy and natural product!
