Firmness Info

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.

The OkiFirm is an 8/10 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 OkiFirm is a 2 layer construction:

  • Cooling Ice Yarn Cover
  • 3" Graphite Foam (Density 2.8 lb, ILD 12)
  • 7" High Density PU Foam (Density 1.5 lb, ILD 36).

Comfort Info
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 OkiFirm's graphite foam provides firm support to keep your body in its desired position and help with back and spine alignment without leaving you feeling like you are floating on top of the mattress. Our densest foam layers provide comfortable but solid support with little give to protect from unwanted contouring.

Comfort Specs

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

Ice Yarn cover is cool to the touch, while the graphite foam with air holes creates a breathable, heat-removing mattress that lets cool air flow so you never overheat.

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.

High-grade graphite foam provides exceptional support while not sinking as much as memory foam.
High-density PU foam provides the proper support needed and is the perfect base layer to pair with the Graphite Foam.

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.

Ice Yarn Zip Cover. This hypoallergenic cover is cool to the touch to help regulate body temperature and prevent you from overheating. The cover is easy to remove and machine washable.
