What's The Difference?

Medium- Soft or Extra-Firm

We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a Medium-Soft mattress - which is our most popular and feels like you're "in the bed".

Some sleepers prefer our Extra Firm model for a more “on the bed” feeling.

    Medium-Soft:

    Perfect for those who like to be supported by their bed, but with a cushioned feel. Choose Medium-Soft if you prefer a plusher feel or are a side or multi-positional sleeper.

  • 2019-04-23_9-33-45.original.jpg
    Extra-Firm:

    Great for those who require sturdy support from their bed, with a robust feel. Choose Extra Firm if you prefer a denser feel or are a back sleeper.

I was skeptical about the "cooling" feature but I can definitely feel the difference in temperature. Convenience, comfort, and cooling...what more can you ask for?!
