Tomorrow Sleep and Leesa are two popular mattress companies that sell directly online.  While Leesa is new on the market and starting to gain popularity, while Tomorrow Sleep is backed by the biggest manufacturer of mattresses in the country. So, which one should you choose? Here’s a rundown of the similarities and differences between them to give you a better idea.

  • Both address sleep temperature in their construction.
  • Similar price range. ($550-1,150 for Tomorrow Sleep, $699-$1,299 for Purple)
  • Both use materials with great pressure relief

Key Differences

  • Purple is all foam while Tomorrow Sleep incorporates coils in the support layer.
  • Tomorrow Sleep has two comfort level options; Purple has only one.
  • Purple uses a unique material that makes it both firm and pressure relieving at the same time (while also being temperature neutral).
  • Purple has a combination of memory foam and latex-like qualities, while Tomorrow Sleep has a very memory foam feel.
  • Purple’s surface is instantly responsive, while Tomorrow Sleep’s is slow-moving
  • Tomorrow Sleep has a foam side rail system for extra edge support.

Tomorrow Sleep Medium Soft Construction

  • A blend of polyester and nylon comprises the cover, which doesn’t affect the overall feel of the mattress significantly.
  • The top layer is 1 inch of dense memory foam with phase change material.
  • 2 inches of less-dense gel foam provide additional comfort and some bounce beneath the top layer.
  • The individually pocketed coils enter in when you get to the support layer. This 6-inch layer is  highly supportive, and uses durable materials that also help with motion isolation.
  • The mattress reinforces edge support with a foam side rail system.
  • At the base of the mattress is 1 inch of stabilizing foam that the steel coils can rest on.

Tomorrow Sleep Medium Firm Construction

  • The firmer version uses the same cover as the softer mattress.
  • The top layer is 1 inch of memory foam that is less dense the top layer of the soft mattress. It also includes phase change material.
  • The next layer is 0.5 inch of breathable comfort foam that incorporates gel.
  • Under that layer is 1.5 inches of “dynamic response foam,” which feels similar to memory foam.
  • The 6-inch support layer is constructed same way as the Medium Soft version, but the coils use thicker wire.
  • The Medium Firm version has the same side rail system as the Medium Soft version.
  • Also like the softer mattress, there is 1 inch of stabilizing foam at the base.

Purple Construction

  • The Purple mattress has three separate foam and hyper-elastic polymer layers.
  • The cover is a breathable blend of viscose, polyester and polyester-lycra.
  • The top layer is 2 inches of hyper-elastic polymer, which is the unique material that gives Purple its particular bounciness, pressure relief and coolness.
  • In the middle is 3.5 inches of relatively dense polyurethane foam.
  • The base is 4 inches of denser polyurethane foam.

Construction Differences/Notes

  • Purple has more spring than Tomorrow Sleep and returns to shape more quickly.
  • Despite the use of springs, you’ll sink into Tomorrow Sleep quite a bit. This is especially the case with the softer version of Tomorrow Sleep.
  • Both sleep cool for most people, but Purple uses special materials that make it a better option for people who tend to sleep hot.
  • While both mattresses are durable, Purple may have a slight advantage because of its highly durable gel material.
  • Purple and Tomorrow Sleep Medium Firm have similar firmness, although Purple feels firm yet pressure relieving at the same time.

Feel Differences

Watch the videos below to get a sense of how the mattresses respond to pressure. Note that the Tomorrow Sleep video is for the Medium Firm version, so expect the soft version to be softer and have more give. Purple is about as soft as the Medium Firm Tomorrow Sleep, but much bouncier. Purple returns to shape more quickly.

Motion Transfer Differences

The videos below show off the differences in motion isolation. Both do a respectable job at preventing motion from transferring.

Pick Tomorrow Sleep If:

  • You like memory foam– If memory foam has worked for you in the past, you might like Tomorrow Sleep better than Leesa. Despite its coils, Tomorrow Sleep has a memory foam feel.
  • You want something extra soft– Both versions of Tomorrow Sleep are pretty soft, but the Medium Soft version especially so.

Pick Purple If:

  • Sleeping cool is your priority– Purple uses special materials that do a better job than memory foam at being temperature neutral. However, Tomorrow Sleep also handles temperature issues well.
  • You want a more responsive mattress– Purple has a faster responding sleep surface that responds instantaneously to spring back into shape. Tomorrow Sleep is more slow moving.
