Firmness Info
Traditional memory foam has a bad rep for having an inconsistent feel based on temperature. Our foam though? It keeps just the right amount of firmness, hot or cold.
Medium Plush Firmness
The 700 Tiny Mattresses independently respond to each sleepers' personal weight and size. When you initially sit on the mattress, it feels very plush because all of your weight is concentrated on a few tiny mattresses. As you lie down, your weight is evenly distributed across all the tiny mattresses for a firmer and more supportive feel. The ingenuity of the "tiny mattresses" provide the back support of a firm mattress with plush comfort for a very luxurious feel.
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 4-inch Purple Grid™ layer is ideal for any sleep position - especially side sleepers. Perfect for sleepers with a soft mattress-feel preference. This is the softest of the Purple mattresses.
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 Origin 2.0 mattress offers excellent support and comfort, customers say it's like sleeping on a cloud! Try the Origin mattress at home for 100 nights. Please note there is a $75 fee that will be deducted from your refund in the event of a return.
The best way to feel the Casper Nova Hybrid is to take advantage of our 100-night, risk-free trial. If you're looking for a mattress that can sustain more weight, or you want to be lifted more than cradled, then our hybrids are a great choice.
The 2-inch Purple Grid™ layer is ideal for back sleepers and those who prefer a slightly firmer feel to their mattress. This is the firmest of the Purple mattresses.

Mattress Construction

Materials Overview
The Silk + Snow mattress uses luxurious ultra-dense 4lb memory foam and is comprised of 3 layers:
  • 2" Luxury 4 lb Supportive Memory Foam
  • 2" Premium 1.8 lb Responsive High Performance Foam
  • 6" Premium 1.8 lb Support Foam
  • Polyester / Spandex / Silver Infused Zipper Cover.
Our "Tiny Mattress" technology is the most significant mattress invention in the last 100 years. There is no other mattress on the market that compares to our one-of-a-kind technology and it's GREENGUARD Gold Certified.
We take a 3" piece of high density hybrid foam optimized for our technology, cut out a 2.25" x 2.25" rectangular cylinder, and then encase it in a fabric pocket. We then attach the Cushion Pocket to a .078" high carbon steel pocketed coil spring to create our patented "Cushion Pocket Spring", better known as the "Tiny Mattress". Finally, we combine roughly 700 of these "Tiny Mattresses" to create a mattress that reacts independently to personal weight and size.
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 4 is made with ultra-high-quality materials engineered for the perfect synergy of durability, luxury, and No Pressure Support:
  • 4" 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 key difference between the Hybrid, Premier 3 and Premier 4 is the depth of the Puple Grid™ layer - either 2, 3 or 4 inches. This changes the overall firmness and feel. The Purple Premier™ 4 is perfect for sleepers who crave even more of that dreamy "floating" effect.
The Origin 2.0 from Polysleep is an upgraded memory foam mattress which is a perfect blend of comfort and durability. The Origin 2.0 mattress is made of three foam layers:
  • 1" Open-cell hybrid foam (Density: 3.0 PCF)
  • 2" Transition polyurethane foam (Density: 1.3 PCF)
  • 7" Supportive polyurethane foam (Density: 1.5 PCF).
(This is the same antimicrobial hybrid foam as the Polysleep Mattress)
Those who want a plush top layer without sacrificing support and cooling. Made with three layers of premium foam, plus foam-encased springs:
  • Breathable AirScape™ Polyurethane Foam
  • Zoned Polyurethane Foam
  • Contoured Memory Foam
  • Durable Base of Polyurethane Foam with Encased Springs.
The Purple Hybrid is made with ultra-high-quality materials engineered for the perfect synergy of durability, luxury, and No Pressure Support:
  • 2" 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.
Comfort Info
When it comes to foam, weight means comfort and quality and our mattress is one of the heaviest on the market. Our ultra-dense 4lb memory foam will give you the plushness and pressure relief you've been looking for and keep that feel for 15 years or more.
The cover's miniature cushion pads provide an added level of comfort and the engineered air channels promote airflow, to maximize the "tiny mattress" technology.
Douglas' CoolSense™ cover and ecoLight™ cooling gel foam layer absorb more heat with faster dissipation, giving you a cooler sleep.
Moisture-wicking CoolSense™ cover
Breathable ecoLight™ cooling gel foam
Fast infrared heat dissipation.
The Purple Grid™ has thousands of open air channels that feel cool as you lie doown and neutralize your body heat throughout the night so you sleep comfortably all night long.
The hybrid foam instantly isolates movement and vibration within your memory foam mattress, so you won't feel your partner or your pet move while you sleep, giving you an even better rest! Antimicrobial foam (medical grade foam ISO 20743:2013 compliant) reduces the growth of bacteria that forms over time in your mattress, this means the life of your mattress is extended and you get a healthier sleep surface.
Cooling helps keep you at the right temperature for your best. Two layers of perforated breathable foam help reduce heat. Plus every mattress saves up to 70 recycled bottles from the environment.

Support Info
Our foam mattress is the perfect hybrid - you'll get the spring and bounce of latex, with the support and pressure relief that memory foam is known for.
700 "Tiny Mattresses" For Absolute Spine Support
Our independent suspension evenly distributes body weight to alleviate stress on the natural curves of the spine. In addition to relieving back pain, this provides absolute comfort for your preferred sleeping position.
Best-in-class spinal alignment for side sleepers. Balanced support for back sleepers. Pressure-point relief for stomach sleepers.

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

Even motion isolation support foam with enhanced edge support.
When it comes to our signature Purple Grid™, the thicker the gel grid, the less pressure you'll feel. 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.

Cooling Air Channels
Our individually sealed cushions create air channels with cool and steady airflow management. Contrary to hot and sweaty sheet foam mattresses, you'll sleep undisturbed and awake refreshed the next day.
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.
Open-cell hybrid foam

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

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.
Open-cell hybrid foam
The top layer distributes pressure, and reduces pressure points, for a comfortable sleep in any position! A perfect balance between comfort and support. Transition polyurethane foam
