Firmness Info
A Single, Fine-Tuned Firmness. Douglas is a medium-firm mattress with a plush, supporting feel and pressure point relief for all sleeping positions.
The 3-inch Purple Grid™ layer is optimal for sleep position changers. Perfect balance of soft and firm for couples with mixed mattress-feel preferences who share the same bed.
Petite customers (115-pounds or less) tend to prefer The Purple Premier, as their pressure points are better cradled due to a thicker Purple Grid. Similarly, customers who weigh 250-pounds or more have expressed a common interest in The Purple Premier, as it offers a bit more support.
The Dawn Mattress is available in two firmness options: * **Medium-Firm**: Ideal for back, stomach, and combination sleepers seeking balanced pressure relief and support. * **Extra Firm**: Perfect for back and stomach sleepers who prefer a firmer sleep surface for enhanced support.

Mattress Construction

Materials Overview
Douglas mattresses are made with Canadian-built foams and fabrics. Three layers of high-quality foam:
  • The top 2" comfort layer is made of ecoLight™ cooling gel foam
  • The middle 2" layer is made of Elastex™ foam
  • The bottom 6" support foam isolates movement and provides better edge support
  • The washable cover is made from an eco-friendly Natural Eucalyptus Fabric™.
The Purple Premier 3 is made with ultra-high-quality materials engineered for the perfect synergy of durability, luxury, and No Pressure Support:
  • 3" Hyper-Elastic Polymer™ material in Puple Grid™. Non-toxic polyethylene copolymer powder coating
  • 1" High-density cushioning foam help the transition between layers for optimal comfort
  • 7.5" Responsive Support Coils. The gauge of the coils are 13.75 and use 95% recycled steel.
The Casper Dawn Foam Mattress is meticulously crafted with three layers of premium polyurethane foam: * **Casper Signature Foam**: This top layer offers a breathable and soothing feel, promoting airflow to keep you cool throughout the night. * **High-Quality Transition Foam**: Serving as a bridge between the comfort and support layers, this foam reduces motion transfer, allowing for undisturbed sleep. * **ProSupport Foam**: The durable base layer prevents sinking and sagging, providing essential support for proper spinal alignment. All foams used are CertiPUR-US Certified, ensuring they are free from harmful chemicals and safe for indoor air quality.

Whether you’re a side, back, or stomach sleeper, the mattress offers balanced support for a restful night’s sleep.
Support Info
Best-in-class spinal alignment for side sleepers. Balanced support for back sleepers. Pressure-point relief for stomach sleepers.
The Perfect Bounce
Douglas' 3-layer design gives it a superior memory effect with just enough bounce for easy movement during the night.
Luxury ecoLight™ fast-response contouring memory foam
High bounce Elastex™ transition layer for spring and support
Even motion isolation support foam with enhanced edge support.
The hyper-elastic polymer gel Grid immediately flexes to support your position and springs back into place as you readjust or move.
The Purple Grid™ is designed to dynamically flex under pressure so it cradles pressure points like your hips and shoulders while still supporting the rest of your body.
A border using high density foam creates reinforced edge support.
The ProSupport Foam layer offers robust support, preventing sinking and maintaining spinal alignment. This ensures that your body is adequately supported, reducing the likelihood of aches and pains.
Comfort Specs
The comfort layer of Luxury ecoLight™ Cooling Gel Foam is made with a 50% smaller carbon footprint, ecoLight™ cooling gel foam is just as durable, responsive, and luxurious as high density memory foam, but won't retain heat or feel like quicksand.
Premium Elastex™ Foam
As durable, supportive, and responsive as natural Latex foam, Elastex™ is made without any of the harmful, allergy-causing chemicals found in many Latex mattresses.
Air circulates more easily through the interior coils, which perfectly complement the Grid's built-in air channels and temperature-neutral gel material.
* **Breathability**: The open-cell structure of the Casper Signature Foam promotes airflow, helping to dissipate heat and keep you cool. * **Motion Isolation**: The High-Quality Transition Foam minimizes motion transfer, so you won't be disturbed by a partner's movements during the night.
Support Specs
Motion Isolation Support Foam
Like millions of tiny pocket-coil springs, Douglas' support foam eliminates motion transfer between sleepers without sacrificing edge support.
Responsive Support Coils
Individually wrapped stainless steel coils pair with the Grid™ to offer dynamic pressure relief and support. Each coil is wrapped in responsibly sourced premium noise-reducing fabric.
The Purple Grid™ is a flexible gel material that instantly adapts to your body and sleep position, providing soft support where you want it and firm support where you need it. 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.
* **Spinal Alignment**: The ProSupport Foam provides a stable foundation, ensuring your spine remains properly aligned regardless of your sleeping position. * **Durability**: The high-density foam construction resists sagging, maintaining its supportive qualities over time.
Fabric Specs
Douglas CoolSense™ Cover
A washable cover made with Natural Eucalyptus Fabric™. Inspired by the mountains of Western Canada, the CoolSense™ cover draws moisture away, leading to a cool, dry night.
StretchMax Cover
Boasting even more stretch, the soft top material allows you to feel the full benefits of the Purple Grid™, while ultra-breathable woven side panels encourage airflow.
The Cozy Knit cover of the Casper Dawn Mattress is made from a cozy, soft knit fabric that feels great against the skin. It is also designed to be highly breathable, helping to keep the mattress cool throughout the night. The fabric is durable, and while it doesn’t need a lot of maintenance, it’s recommended that you spot clean any stains to preserve its fresh feel.
