Conforming Support
Featuring a ventilated React™ foam technology for conforming pressure relief, this mattress is designed for deeper, more restful sleep.
Independent Suspension™
Independent Suspension™ units are interchangeable support layers that allow you to choose the firmness for each side of the bed. Made with hundreds of individually wrapped coils, each unit works independently to provide responsive support that caters to your preferences so you never have to compromise on comfort.
Customized Responsive Support
Each unit works independently for customized, responsive support while limiting motion transfer throughout the bed.
Removable & Recyclable
If your comfort preference changes over time, simply remove your Independent Suspension™ unit and swap it for a new one.

Four firmness levels to choose from
The comfort layer is made up of three layers of Boost® ventilated to channel heat away from your body and help air circulate throughout the mattress.
Top Layer
Quickly responds to your body with an elevated feel
Middle Layer
Isolates motion caused by body movements throughout the night
Bottom Layer
Absorbs pressure for a more supportive, comfortable sleep
Bedding That Breathes
Every layer of the M3 is enhanced with airflow features that work together to keep air circulating throughout the mattress.
Comfort Layer
The Boost® comfort layer is ventilated to channel hot air away from your body and into the mattress.
Independent Suspension™
Independent Suspension™ units feature coils wrapped in a breathable fabric that allows air to circulate
Chassis
Breathable Air-X® fabric and built-in air vents on the Chassis create cross-ventilation and increase breathability within the mattress.
When things get hot, M3 keeps you cool
More airflow = less heat buildup. Every layer of the M3 works together to keep warm air moving so it’s never trapped inside the mattress.
The silky-smooth cooling Ver-Tex™ top cover reduces overheating while you sleep and feels instantly cool against your skin.
The M3 works throughout the night to help your body maintain a comfortable temperature so you can experience deeper, more restorative sleep.
A mattress designed to change with you
Our 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.
Lighten Your Carbon Footprint
It’s simple – less waste is better. We engineered our M3 sustainably with a modular design for personalized sleep, and we believe in getting it right the first time so we can end the wasteful cycle of buying, returning, and throwing away.
The M3 is built modularly so you can choose your comfort, clean, maintain and swap components, helping to expand the lifetime of your mattress.
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 and lightening your carbon footprint along the way.
Sleep Clean & Healthy
Designed for Quick and Easy Cleaning
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.

What Our Happy Sleepers Say
Posted on Nancy AlexanderTrustindex verifies that the original source of the review is Google. My 10 year old mattress was trying to kill me! I'd toss, turn, and wake all achy. The Somnus Haven bot recommended a Posh + Lavish mattress, and I'm happy to be writing this review while still in it:) I feel like I'm being cuddled by a luxurious marshmallow that gives me beautiful sleep, and that's precious to me. Thank you to Tam, the Somnus Haven owner, for enlightening me on the benefits of a high quality mattress. Amazing customer service, too.Posted on Whitney DuenasTrustindex verifies that the original source of the review is Google. Somnus Haven has the BEST sheets around.
