With our unique modular approach to mattress design, you can swap out layers at anytime to change the way your bed feels. You can even change your mind years later! Additionally, you can split the bed internally to accomodate separate comfort levels for you and your sleep partner. This flexibility eliminates the comfort risk associated with buying a new mattress. If you discover that you need a different level of support for example, you can easily swap out your configuration for something softer or firmer until you get things just right.
