| 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. | 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. | When we designed the Casper Element, we knew we had to deliver lasting comfort at an unbeatable price. It borrows elements from our signature mattress to promise coolness and support in a more cost-efficient design. | Puffy is a Medium-Firm, rated a 6 to 8 on the firmness scale. | N/A | It rates as a medium-firm mattress, but really combines the best of both firm and soft products. It's the perfect balance of comfort and support. Our provides superior pressure relief, with little bounce, and zero motion transfer. Essentially you feel like you're floating on a cloud. Unlike other memory foam mattresses, we sped up our foam's response rate so that you don't sink too far down into the core, and so you don't feel stuck in the foam. | 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. |
Mattress Construction | |||||||
| Materials Overview | |||||||
The Silk + Snow mattress uses luxurious ultra-dense 4lb memory foam and is comprised of 3 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 Purple Hybrid is made with ultra-high-quality materials engineered for the perfect synergy of durability, luxury, and No Pressure Support:
| We made an expensive mattress that's not expensive. The sweet spot between superior comfort and serious value. It's a premium mattress in a streamlined design. 2 layers of polyurethane foam:
| Puffy has three layers of construction:
| The Zephyr Mattress is made of 5 layers of polyurethane foam:
| 4 layers of construction:
| 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:

| 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. | 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. | Cooling helps keep you at the right temperature for your best rest. We also own the manufacturing process, so we can guarantee all Casper mattresses meet our high standards for comfort. Plus every mattress saves up to 9 recycled bottles from the environment. | 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. | Using organic cotton fibers and Nanobionic® Technology, the Zephyr Mattress transforms your natural body heat into regenerating infrared rays. The benefits of infrared rays on the body are widely recognized. It's been proven that they are very beneficial in the energetic and restorative processes of the human body. This advanced technology allows you to recover better, especially after heavy physical exertion. You'll wake up recharged and feeling great! | Four layers of high-density memory foam, refined through two years of R&D and 27 rounds of prototyping to provide the perfect balance of comfort, support, responsiveness, and breathability. | Ultra breathable cover and hybrid design increase airflow to keep the mattress cooler. No more sweaty nights. |

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. | 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 durable base is engineered to prevent sinking and sagging while supporting your whole body. | The Puffy mattress offers balanced support and contouring, making it perfect for all types of sleepers. | The integrated support frame keeps your mattress from flattening when you sit on the edge, and reinforces the structure. This allows you to sleep right on the edge - maximizing your mattress surface. | Our four-layer weightless foam system combines a plush top layer with increasingly firmer base layers, to deliver an optimal combination of comfort and support. We refined our mattress through 27 rounds of testing, optimizing for pressure-relief at all five key pressure points. We tested a range of body types and sizes, ensuring that the W1.27 would be supremely comfortable for almost all people, while still providing full body support. | 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. |
| Comfort Specs | |||||||
A luxury 4 lb memory foam layer that provides a cooler, more consistent sleep surface every single night - 13x better than conventional memory foam, 16x better than latex. | 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. | Air circulates more easily through the interior coils, which perfectly complement the Grid's built-in air channels and temperature-neutral gel material. | 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. | Puffy's Cooling Cloud draws heat out of the mattress with its Cloud Gel layer to keep your body at an optimal temperature for 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. | Using GelFlex Plus, our premium memory foam topper is infused with gel particles. It cools you down when you're hot, and warms you up when you're cold. Breathable Hybrid Foam helps to regulate your body temperature. Our antimicrobial technology in the Antimicrobial Foam layer helps to reduce bacteria growth, and works as a protective shield against allergies. | To keep our mattress from overheating, we developed an extraordinary new foam called 3BELOW™. It's a fully breathable, open-cell material, infused with heat-conductive gel particles. That means it actually draws heat from your body and disperses it throughout the mattress so it escapes more quickly. As a result, the W1.27 sleeps three degrees cooler than other foam mattresses, right in the sweet spot for deep, uninterrupted sleep. | 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. |

A premium 1.8 lb high performance foam transition layer that provides the spring and bounce you'd find in a latex or coil bed, while providing unparalleled support, pressure relief and motion isolation. This durable 1.8 lb premium support layer is the foundation to it all. Strength, support and structure of the mattress starts here. | 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! | 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. | Premium AirScape™ foam conforms to your body to relieve pressure. | Puffy's Cooling Cloud and Firm Core Support foam will adapt perfectly to every point of your body, letting you forget you're even on a mattress. Puffy's Firm Core Support Layer is specially designed to keep your spine aligned while eliminating pressure points. | Targeted Zone Support: Your shoulders and hips need a different level of support, so we've adapted the density of our foam according to these areas of your body. Our foam is softer on the shoulder zone, to reduce the pressure felt from day-to-day activity. The hips and torso zone features firmer foam which provides better alignment for your spine. | The core of our W1.27 is 100% viscoelastic memory foam. We tested every possible material, including memory foam, latex foam, coils, coil / foam hybrids, hand-rolled cotton, horsehair, and found that memory foam gives us the greatest precision in crafting a truly great product. We've made the best memory foam mattress on the market. The W1.27 achieves unparalleled balance, meaning that it's supremely comfortable to lay on, but also provides better body support than other products. | 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. |

Ultra-Soft Premium Cover A top cover made from one of the world's smartest natural materials. We used an innovative antimicrobial textile, powered by pure silver to help prevent the growth of unwanted bacteria. Our silver technology is woven into the fibers, allowing the fabric to feel soft and luxurious. | 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). | 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. | N/A | Your Puffy comes with an all-new Stain Resistant Cover!
