| Firmness Info | |||||||
The Douglas Summit mattress offers a medium-firm feel, striking the ideal balance between comfort and support:
* Firmness Level: Medium-Firm (6,5 on the firmness scale), suitable for all sleeping positions.
* **Adaptive Comfort**: The mattress contours to your body, providing personalized support without feeling too soft or too firm.
This balanced firmness ensures that you receive the necessary support for spinal alignment while enjoying the plush comfort that leads to restful sleep. | 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. | Puffy Lux is a Medium firmness, rated a 5 to 7 on the firmness scale. | The Simba 1500 is a firm feel, the Simba 2500 is a medium-plush feel and the Simba 5000 Pro Flex is a plush feel. Simba used body profile data from 10 million sleepers (making up over 180 million profile points) to create a mattress designed for every sleep style and body type. Backed by a 100-night trial and 100,000+ five-star global reviews. | 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 Endy Hybrid, like the classic, is also considered a medium-firm firmness. The mattress offers the perfect blend of comfort and support. Whether you prefer resting on your front, back, or side this mattress is recommended for you! | Medium feel top of the bed you need - not too firm, not too soft. Rated a 7 to 8 on the firmness scale. Maximum support - to help provide maximum support for people with high BMIs. | 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. |
Mattress Construction | |||||||
| Materials Overview | |||||||
The Douglas Summit mattress is crafted with precision using only the finest materials to ensure unmatched quality and durability:
* **Eco-Friendly Memory Foam Layers**: CertiPUR-US® certified for safety and sustainability. These layers provide exceptional comfort while maintaining an environmentally conscious approach.
* **ecoLight Cooling Gel Foam**: This innovative foam requires up to 40% less carbon input to produce compared to traditional high-density memory foam, offering the same durability and responsiveness without retaining heat.
* **Sustainable Infinitex Fibres**: Utilized in the mattress cover, these fibres are derived from sustainable sources, providing a soft and breathable surface that enhances overall comfort.
From the first touch, you’ll notice the premium quality of every layer, designed to give you the sleep you’ve always dreamed of. | The Purple Premier 4 is made with ultra-high-quality materials engineered for the perfect synergy of durability, luxury, and No Pressure Support:

| The Helix Plus is designed for Plus Size and Big & Tall and offers maximum support with a medium feel, it has five layers of construction:
| 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. |

This isn’t just a mattress—it’s your personal retreat, designed to cradle you into blissful sleep. | 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 ClimateComfort layer was expertly crafted to resist contraction and expansion during temperature fluctuations, which results in the same consistent feeling year-round. It also acts as a temperature neutralizer, keeping you in a stable and relaxing sleep. | The world’s most 5 star rated mattress is engineered for optimal sleep. The engineered support base, along with the unique combination of conical pocket springs and memory foam, allows two people with different sleeping patterns and body types to enjoy the perfect night's sleep - without being interrupted by each other. | Douglas' CoolSense™ cover and ecoLight™ cooling gel foam layer absorb more heat with faster dissipation, giving you a cooler sleep.

| Support Info | |||||||
The Douglas Summit mattress doesn’t just focus on comfort—it delivers on support too:
* **Full-Body Support System**: The high-density support foam layer ensures optimal spinal alignment, no matter your sleeping position.
* **Motion Isolation Technology**: Share your bed without compromise. The advanced design minimizes motion transfer, so you can sleep soundly even if your partner moves.
* **Reinforced Edge Support**: Sit or sleep comfortably on the edge without worrying about sagging.
Every detail of the Douglas Summit Mattress is engineered to provide the kind of support that promotes healthy sleep and reduces aches and pains. | 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. A border using high density foam creates reinforced edge support. | The Puffy Lux was designed to be the perfect mattress for all types of sleepers - back, side or stomach sleepers. Luscious comfort and exquisite support for your spine. The total active support and contouring offers enhanced spinal alignment. The Lux also has targeted full body pressure relief. | N/A | 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 Hybrid Mattress is recommended for sleepers who want maximum levels of support from durable pocket springs and zoned lumbar support. The Canadian-made steel coils provide extra support to the areas that need it most. | The new Helix Plus has higher density foams to match heavier sleepers and provide increased durability. The coil unit has best in-class edge support, so plus size sleepers never feel like they're falling off the mattress. An extra layer of high density, 4 pound foam is included in one of the three foam layers to help provide maximum support for people with high BMIs. | 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. |
| Comfort Specs | |||||||
The Douglas Summit is crafted to suit a wide range of sleep preferences:
* **Perfect for All Sleepers**: Whether you sleep on your side, back, or stomach, the mattress adapts to your unique needs.
* **Pressure Relief Technology**: Relieves tension on common pressure points like shoulders, hips, and lower back, ensuring you wake up pain-free. | Air circulates more easily through the interior coils, which perfectly complement the Grid's built-in air channels and temperature-neutral gel material. | Puffy's Cooling Cloud draws heat out of the mattress with its Cloud Gel layer to keep your body at an optimal temperature for amazing sleep comfort. Our Puffy mattresses incorporate an advanced temperature-stabilizing, ClimateComfort™ layer that prevents sudden temperature swings that can disrupt a comfortable night's sleep. Expect a subtle warming effect during the cold winter months and a cooling effect during a hot summer. | The Simbatex foam has an open-cell structure and uses advanced graphite cooling technology to draw heat away from your body, keeping you cool and comfortable. Patented miQro springs allow air to move freely through the mattress - unlike pure memory foam which traps heat in. | 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. | Open-cell foam provides optimal airflow and breathability for cooler sleep.
Pocket coils complement the signature open-cell foam to create the most refreshing sleep experience of your life by providing added airflow.
All Endy foam is certified by CertiPUR-US for clean comfort.
| Our special latex-foam hybrid alternative, designed to be denser to contour to your body. Uniquely pressure relieving, we use 4 pound Memory Plus Foam - a special, ultra dense and extra durable Helix blend. | 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. |
| Support Specs | |||||||
The Douglas Summit mattress is built to last, offering a support system designed to cater to a variety of body types and sleeping styles:
* **High-Density Core Foam**: Delivers consistent support and prevents sinking, even for heavier sleepers.
* **Responsive Design**: Adjusts to your movements, so you never feel stuck or unsupported.
* **Durability Guaranteed**: Backed by a 20-year warranty, this mattress is a long-term investment in your sleep health. | 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. | The Puffy Lux's Cooling Cloud and Body Adapting Dual Cloud Foam work in tandem to melt the stress and strain from your body's pressure points. The Puffy Lux's Firm Core Support Layer is specially designed to keep your spine aligned while eliminating pressure points. | Featuring up to 1,500 unique conical pocket springs, these individually adjust as you sleep, ensuring body weight is evenly distributed for true gravity-defying comfort.

The perfectly engineered support base has different zones to ensure a perfect night's sleep for all. | Motion Isolation Support Foam Like millions of tiny pocket-coil springs, Douglas' support foam eliminates motion transfer between sleepers without sacrificing edge support. | Comfort Foam gives a "perfect" medium-firm support.
Transition foam is designed to promote pressure relief and eliminate motion transfer for undisturbed sleep.
Hundreds of high-carbon steel coils offer unparalleled support and extra firmness in the areas that need it most.
High-density foam keeps your mattress perfectly firm and supportive for years.
| Firm Memory Foam provides ergonomic support and cushioning, the transition layer has a higher IFD to match your body type. Extra support. Hundreds of individual taller coils designed to cradle and support heavier weight. Reinforced perimeter to provide edge support. The bottom foam layer of the mattress provides base support and durability to the entire mattress. | Individual Vertebrae Support The individual suspension system supports each bone (33) in the human spinal column separately. It cradles the body's curves while providing enough firmness for the back's muscular and bony structures. Plus it's Chiropractor Endorsed! |
