Let’s face it: most of the jargon you come across when choosing a new mattress doesn’t actually help you make a decision, instead it causes extra confusion. The good news is that the Casper mattress doesn’t need you to choose between half a dozen zone layouts and firmness levels. We have done all the hard work for you - creating a mattress with a unique combination of high-quality foam layers. The result? A bed that is soft enough to cradle you like a baby and firm enough to support you perfectly throughout the night:

• Open-cell foam: Provides comfort and reliable breathability
• Memory foam: Adapts to the shape of your body and relieves your shoulders and hips.
• Transition foam: Firm yet soft, this layer acts as a transition to the firm base foam.
• Support foam: Thick layer that supports your weight and keeps the mattress in shape.
  
  The Casper’s layout works for the vast majority of sleepers, regardless of their preferred sleeping position or body size - all you have to choose is the size that fits your bed. Not sure which size is for you? Feel free to call us or send us an e-mail and we’ll help you choose.
