Casper Wave Construction

  • Casper Wave is wrapped in a thick, soft, durable cover. Its top layer is 1″ of proprietary “Flo Foam,” which is soft and relieves pressure.
  • The second layer is 1.5″ of supportive latex foam, which is followed by a 1.5″ layer of responsive, visco-elastic memory foam.
  • 1.5″ of high-resiliency foam with a polymer network helps distribute weight evenly. This layer works with the 5.5″ base layer to create the Wave’s zoned support system. Key to this system are contour cuts in the foam of the supportive base.

Sapira Construction

  • Sapira has 1.5″ of breathable Avena foam on top, giving the mattress bounce. This latex-like layer also helps ensure cool sleeping.
  • The middle layer is 1.5″ of memory foam, which helps the mattress conform to contours. This layer also gives Sapira a balanced foam feel.
  • The supportive bottom layer contains steel coils sandwiched by 1″ layers of stabilizing foam. This structure helps give Sapira its great edge support.

Firmness/Feel Differences

Both have responsive surfaces, but Casper Wave is softer and has a lighter feel.

Motion Transfer Differences

Both isolate motion well, though Casper Wave has a slight edge because it is softer. Either is a good option for couples.

Pick Casper Wave If …

  • You are a side sleeper. Casper Wave is softer overall, has zoned support, and conforms better to contours. It will be softer underneath your shoulder than the Sapira will be, potentially making it more appropriate for side sleepers.
  • You want something softer. Casper Wave is softer, and you will sink into it more. If you’re looking for something softer, then the Wave may be the way to go.

Pick Sapira If …

  • You want a firmer mattress. Sapira’s coils and Avena foam top layer make it firmer.
  • You are heavier. Sapira’s steel coil system makes it more supportive for people who weigh more.
