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 Tuft & Needle Mint mattress is medium-firm in feel, but softer than the Tuft & Needle Original. The Mint Mattress is optimised for side-sleepers and is slightly more plush for added pressure relief. | Award-winning comfort, signature "just right" feel. | The best way to feel the Casper Original 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. |

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 Mint has an extra layer of T&N Adaptive® foam for added comfort (when compared to the Original). Infused with cooling ceramic gel and 30% more heat-conducting graphite than our T&N Original Mattress, the Mint offers optimal sleeping temperature throughout the night. | Casper mattresses are specifically designed to sleep cool. We put a lot of R&D into how Casper mattresses perform throughout the night - like running thermal imaging tests and sweat tests. Our mattresses use a breathable comfort foam to offset the memory foam layered beneath it. This construction helps keep things nice and breezy and outrageously comfortable. Plus every mattress saves up to 57 recycled bottles from the environment. | Casper mattresses are specifically designed to sleep cool.

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. | Reinforced edges provide support for edge-of-bed sleepers and make it easier to get in and out of bed without disturbing your partner. | The durable base is engineered to prevent sinking and sagging while supporting your whole body. | We designed our own proprietary foam for our "just right" feel, and are now integrating those layers with resilient-yet-gentle fabric-wrapped steel springs. A firmer border provides edge support to help you get in and out of bed easily. |
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. | T&N Adaptive® Foam Invented with the help of top American chemists, this open-cell foam is durable, breathable, and with the perfect amount of give. Graphite The addition of heat-absorbing graphite is designed to conduct heat through the bed, away from you. Cooling Gel Beads When pressure is applied to the ceramic cooling gel beads in the second layer, they stack on top of each other and create a unique cushioning support. | A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away. This innovative cooling system is designed to help keep you cool all night. | A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away.

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 top layer of the Mint is softer than that of the T&N Original, but with a firmer bottom layer for added edge support. This added third layer, the Mint layer, is designed to reduce motion transfer and provide additional pressure relief and softness.
The Mint also has a middle transitional layer to keep you from "bottoming out". | Premium AirScape™ foam conforms to your body to relieve pressure. Memory foam with 3 areas of Zoned Support™ help align your spine and relieve pressure. Softer under shoulders and firmer around the hips, waist and lower back. | Premium AirScape™ foam conforms to your body to relieve pressure.

* **Eco-Conscious Design**: Produced with sustainability in mind, the cover supports your values while enhancing your sleep.
* **Easy to Maintain**: The machine-washable cover makes keeping your mattress clean and fresh effortless. | 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. | Plush-Knit Fabric A thick, cozy knit cover that remains breathable and includes HeiQ NPJ03 to protect your mattress from odour-causing bacteria that can affect its lifespan. | N/A | N/A |
