Construction

DELIBERATE DESIGN: The M3 is built modularly so you can choose your comfort, clean, maintain and swap components, helping to expand the lifetime of your mattress.
CLIMATE CONTROL: The silky-smooth cooling Ver-Tex™ top cover reduces overheating while you sleep and feels instantly cool against your skin.
COOL COMFORT: Three layers of ventilated Boost® foam technology conform to your body, providing enhanced comfort and support where you need it.
REACTIVE RELIEF: Top layer quickly responds to your body with an elevated feel.
MINIMIZE MOTION: Middle layer isolates motion caused by body movements throughout the night
SUPPORTIVE SLEEP: Bottom layer absorbs pressure for a more supportive, comfortable sleep.
RESPONSIVE REST: Independent Suspension™ units made with hundreds of individually wrapped coils provide customized responsive support.
PERSONALIZED PERFORMANCE: Each unit works independently and are interchangeable to choose the firmness for each side of the bed so you never have to compromise on comfort.
ADDED AIRFLOW: Breathable Air-X® fabric and built-in air vents on the Chassis create cross-ventilation and increase breathability within the mattress. Independent Suspension™ units feature coils wrapped in a breathable fabric that allows air to circulate.
FOAM FOUNDATION: Chassis made of a high- density foam base that contains the Independent Suspension™ unites and provides durable edge support.
MODULAR MAKE: Interchangeable modular design allows you to modify various components if your comfort preferences change. The chassis remains the foundation of your M3 while the top cover, comfort layer and Independent Suspension™ units are easy to remove and swap when needed.
REMOVABLE & RECYCLABLE: When your comfort preferences change, or if a component needs to be replaced, simply replace the pieces that no longer suit you, rather than disposing of an entire mattress - keeping more waste out of landfills.
HEALTHY & HYGIENIC: The Ver-Tex™ top cover and the removable comfort layer cover are machine washable. Combat dust by removing the Independent Suspension™ units to vacuum the inside of the chassis.
ADJUSTABLE ADVANTAGE: Mattress is compatible with adjustable bed bases for an elevated sleep experience.
CERTIPUR-US®: Low-VOC foam is certified to CertiPUR-US® standards, which ensures it is made without PBDEs, TDCPP or TCEP (“Tris”) flame retardants, ozone depleters, heavy metals, formaldehyde, and phthalates regulated by the Consumer Product Safety Commission.
