Casper Nova Hybrid vs SleepOvation is now Kiwi Sleep

The best way to feel the Casper Nova 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.

The SleepOvation mattress is meant to relieve back-pain and correct your sleeping posture, it does feel on the firmer side but not because the mattress itself is firm - but because it's correcting your spine. It's actually a very comfortable plush mattress, but someone who suffers from severe back pain, will feel the mattress to be much stiffer than someone with a healthy spine.
It's difficult to compare our mattress to the traditional firmness standards of other mattresses simply because nothing like the 700 tiny mattresses exist.

Those who want a plush top layer without sacrificing support and cooling. Made with three layers of premium foam, plus foam-encased springs:

• Breathable AirScape™ Polyurethane Foam
• Zoned Polyurethane Foam
• Contoured Memory Foam
• Durable Base of Polyurethane Foam with Encased Springs.

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.

Cooling helps keep you at the right temperature for your best. Two layers of perforated breathable foam help reduce heat. Plus every mattress saves up to 70 recycled bottles from the environment.

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.

Superior plushness without sacrificing support. More support where you need it most with the plushness you crave. Zoned Support™ Pro offers 7 zones of targeted support for healthy spinal alignment, softer foam around the shoulders provides more relief to the upper body and multiple ergonomic points under shoulders, hips, waist and lower back.
A firmer border provides edge support to help you get in and out bed easily.

700 "Tiny Mattresses" For Absolute Spine Support
Our independent suspension distributes body weight to relieve back pain, discomfort, and restlessness caused by sheet foam layers in other mattresses.

A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away. With a thin coating of cooling gel that adds a refreshing feel. This innovative cooling system is designed to help keep you cool all night.
Second layer of AirScape™ helps prevent overheating. These air channels allow heat to escape.
Resilient springs increase airflow.

Cooling Air Channels
Avoid the headaches of sleeping hot and sweaty on sheet foam or other advertised "cooling" technology that do little to prevent heat. Our air channels are designed to maintain cool temperatures for a refreshing night's sleep.

Premium AirScape™ foam conforms to your body to relieve pressure. This has a plush, velvety soft feel.
A second layer of supportive foam has 3 ergonomic zones to help align your spine and provide more relief.
A third layer with Zoned Support™ Pro relieves pressure under the shoulders, and provides more support under the waist, lower back, and hips to align your spine. These zones reinforce support from the layers above.
Fabric-wrapped springs provide active support and a little lift.

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!

A super plush and stretchy top. This velvelvety-soft layer makes bedtime feel extra cozy. Knit fabrics stretch in 4 ways so you feel the full benefits of the layers below. The added pillow-like fabrics cradle your body and make you feel as if you were sinking into a cloud.

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.
