Comfort	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. 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.	The ventilated viscoelastic hybrid foam is anti-microbial and prevents any moisture from accumulating. 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.
Support	The durable base is engineered to prevent sinking and sagging while supporting your whole body. 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.	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. 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.

FAQs

Casper Original

Can I sleep on my Casper right away?

Casper mattresses are designed to be slept on immediately after they have fully expanded. Unlike some mattresses that may soften over time, it's typically your body that adjusts to the mattress.

Has Casper original changed?

The new version of the Casper Original is a medium firmness mattress. The previous version was slightly firmer and had two comfort layers, a zoned transition layer, and a bottom support layer. The new version has removed the second comfort layer and replaced the zoned transition foam with zoned memory foam.

How many years does a Casper mattress last?

While the lifespan of a mattress can typically range from 7 to 10 years, Casper asserts that their foam mattresses can endure up to 12 years. This duration extends well beyond the 100-day return policy, ensuring that you receive a good return on your investment.

Polysleep

What is the weight limit for Polysleep?

Polysleep mattresses are suitable for individuals weighing up to 250 lb.

Can you flip a Polysleep mattress?

The Polysleep mattress is not designed to be flipped. It is constructed with comfort layers on top and support foam on the bottom to provide body contouring and pressure point relief. Flipping it would compromise its comfort.

How thick is the Polysleep mattress?

The Polysleep mattress has a height of 10 inches.
