  • Summary:

  • Casper is one of the early market leaders in the foam mattress space and offers a good universal mattress for the average sleeper.
  • Casper has crafted a memory foam mattress that is breathable and promotes airflow, so you won’t get that hot, sinking feeling that you would with traditional memory foams.
  • The Casper team is continually refining its design based on customer feedback and sleep tests; so buying a Casper today doesn’t necessarily mean it’s the same one from a couple years ago. Casper’s latest innovation – Zoned Support – is a new foam system that contours high-pressure areas like your hips, shoulders, and core to provide relief and support where it’s needed most.

  • The Purple is a mattress with a big personality, but it does have a lot to boast about: it sleeps cool, is great for spinal alignment and does a good job with reducing any movement you’ll feel from other people (or animals).
  • Customers who own the Purple have claimed it’s helped them relieve back and neck pains.
  • The Purple is topped with a unique pressure-releasing material that is especially great for back and side sleepers – when you lie on your back, it will help your spine maintain its natural curve and when you lie on your side, it will help keep your spine straight.

Video showing how the Casper mattress is made

The Purple mattress is made with a layer of hyper-elastic polymer (designed to provide great pressure relief) on top of two layers of high-density polyurethane foam (designed for durability, support and motion isolation). Here’s a look at the layers, described from top to bottom:

  • Responsive Knit Cover: Soft and stretchy cover that helps maximize the flexing properties of the Smart Comfort Grid™. The breathable design also promotes airflow to help you sleep cool.
  • Smart Comfort Grid™: Designed to cushion your shoulders and hips (pressure points), and support your body’s natural shape.
  • Plush Comfort Foam: Soft, high-density polyurethane foam designed to enhance the responsiveness and feel of the Smart Comfort Grid™.
  • Support Foam: Medium-firm, high-density polyurethane foam provides structural support to the mattress.
