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.

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)
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.
The Douglas Alpine mattress features a carefully selected combination of materials that prioritize comfort, durability, and environmental responsibility: * EcoLight Cooling Gel Foam: A proprietary foam that delivers superior cooling and pressure relief while using up to 40% less carbon input than traditional memory foam. * Premium Elastex Foam: A latex-like foam that is hypoallergenic and offers responsive support without the heat retention of traditional latex. * Motion-Isolation Support Foam: This dense foam layer reduces motion transfer, ensuring uninterrupted sleep for couples. * Machine-Washable Cover: The mattress is wrapped in a stretch-knit, breathable fabric cover made from sustainable materials for added convenience and longevity. These materials are not only high-performing but also eco-conscious, aligning with the growing demand for sustainable products.
Comfort Info
