| 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. | 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. | 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. | 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. | The 6" base foam layer adds strength, durability and structure to support sleepers of all sizes, without feeling too firm. | The ultra-plush feel of the Puffy Royal is perfect for sleepers seeking an extra-luxurious night of sleep. Ideal for all sleep positions. It is rated a 4-6 on the firmness scale. |
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 Simba® 1500 is built for those who are looking for a firmer comfort. 4 layers:
| 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. | 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:
| 3-Layer Foam Construction

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 world’s most 5 star rated mattress is engineered for optimal 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. | N/A | 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. | 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. | The Leesa mattress is designed to cradle and support your body while avoiding the sinking feeling and overheating found in other foam mattresses. | The innovative 7-layer sleep system of the Puffy Royal foam mattress has been engineered to deliver advanced cooling, body-adaptive contouring, and full-body zoned support. |
| 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. | 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. | 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. | 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. | LSA200 Foam The 2" foam top layer provides airflow for a cooler night's sleep and enough bounce for freedom of movement. | Infused Cooling Foam + Plush Contouring The Puffy Royal foam mattress is formed with a unique cooling layer infused with special cooling gel. Experience less heat retention for the most consistent deep sleep you have ever experienced. Reflexive Memory Foam Gently contouring memory foam delivers true cloud-like comfort. Cloud Air Technology The unique cloud design enables the Puffy Royal to minimize heat absorption, resulting in superior airflow throughout the mattress. Sleep deeper and for longer in optimal temperature year-round. |

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. | 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. Simbatex memory foam moulds expertly to your body shape. It's like a mattress tailor made for you.

This European designed hypoallergenic waterfall cover is not removable or washable. The grey base fabric can be cleaned with a soft, damp and clean cloth using small circular motions. Using a mattress protector could help extend the life of your mattress. | Our stretch knit polyester and elastane cover is designed to complement the "tiny mattresses" ability to adjust to personal weight and size. More specifically, we've integrated a quilted, internal (FR) mattress pad that offers a more plush level of comfort. This zip-off removable and washable cover allows access to independently sealed cushions and unmatched cleanliness (vacuum in-between each air channel so you can eliminate dust, bacteria, and allergens). | Each Plus mattress comes with our Ultra Breathable Tencel technology designed to increase airflow and to keep you cool. | The Leesa Mattress is wrapped in our iconic four-stripe cover that features fire retardant properties. | Stain-resistant cloud cover Is designed for maximum usage.
