Casper Nova Hybrid vs Polysleep

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.

At Polysleep, we designed the Polysleep Mattress to suit all types of sleepers. Our goal was to balance the right amount of comfort, support, quality and firmness into one ideal mattress.

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.

The Polysleep Mattress is made of three horizontal layers and a vertical layer of polyurethane foam. The Premium Foam layers:

• 3" Viscoelastic Hybrid Foam (Density: 3.0 PCF)
• 1.5" Support Foam (Density: 1.8 PCF)
• 5.5" High-Density Support Foam (Density: 1.8 PCF)
• Proprietary Support Frame (Density: 2.0 PCF)
• Liquid repellent cover.

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 ventilated viscoelastic hybrid foam is anti-microbial and prevents any moisture from accumulating.

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.

An element that makes this mattress truly unique is the proprietary support frame. This keeps the mattress from flattening out when you sit along any of the edges and helps to reinforce the structure.

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.

The top layer allows air to circulate, keeping you cool while adapting to your body. It identifies the pressure points, reduces the temperature and the firmness of these points in seconds only.

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.

The support layer serves as a transition between the top layer and the base. It is designed for your comfort and provides full body support to ensure a better sleep.
The first layer, or base, of the ultimate mattress is built with high-density foam and acts as a boxspring, while providing unparalleled reinforcement. It adds durability, strength and comfort without feeling too firm.

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.

The cover gives you a delicate, soft feel to lie on. It is also liquid repellent to avoid any accidents. The sides are made of mesh, which allows the mattress to be more breathable.
