Firmness Info

Softer top of the bed to give you that plush comfort you love. Like sinking into a cloud. Balanced support - best for side sleepers with thin to average body types. A 2-3 on the firmness scale.

Everyone has their ideal comfort level. That's why we've designed this comfort selector tool so that you know exactly what you're jumping into. Select from 3 firmness levels:

  • Soft, a 3/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
  • Medium, a 5/10 on the firmness scale, the best of both worlds for an exceptionally comfy feel.
  • Firm, a 10/10 on the firmness scale, solid and stable support throughout your sleeping surface.

Mattress Construction

Materials Overview

The Sunset offers balanced support and a plush feel, it has four layers of construction:

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

The Intention Mattress by Diamond Mattress is constructed of:

  • 1.5" CoolTouch Temperature Regulating Fabric & Luxury Quilt
  • 1.5" Diamond Hyper Conductive Sparkle Foam
  • 2" HD Comfort Layers
  • Patented Zoned Support System - Foam Encased.

Comfort Info

Foam Encased Comfort Edge: Increases usable sleep surface by allowing you to sleep all the way to the edge without feeling like falling off. Creates a better edge for entering, exiting and sitting on the side of the mattress.

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.

Combination Foam and Coils: Superior Pressure Relief. Contours to your natural shape to help achieve a comfortable sleeping posture. Hyper conductive foam regulates core temperatures for a natural sleep. Coils provide breathability and additional comfort and support.

Comfort Specs

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

Diamond Sparkle Foam actively regulates your core temperature for the most natural sleeping environment. Graphene and conductive flakes dissipate heat from the surface of the skin.

Support Specs

Helix Dynamic Foam
Providing ergonomic support and cushioning, the transition layer has a lower 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.

Patented Zoned Support System: Adding 25% more support where you need it most

  1. Additional Wrapped coils in the center 3rd provided extra back support where you need it.
  2. Improves alignment by relieving pressure along the shoulders, back and hips
  3. Prevents motion transferred between partners for less disturbance
Diamond Sparkle Foam provides superior pressure relief for sound sleep.

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.

CoolTouch Temperature Regulating Fabric:

  • Actively moves excess heat away from the skin where it can dissipate to maintain a comfortable sleeping environment
  • Special conductive yarns allow heat to move through the fabric while wicking moisture away from the body sleeping environment
  • Luxury stretch knit design contours to your body relieving pressure and enhancing conformability and pressure relief.
