M3 Mattress Coils

The M3 Mattress Coils are what make the M3 mattress unique- you can combine two different feels in a single bed by selecting different coil systes for each side! Rated on a scale of 0.0 (firmest) to 3.0 (softest), these coils make it so that you never have to compromise feel with your partner.

**NOTE: For NEW M3 mattress setups of any queen or king configuration, you will need TWO coil units to complete your mattress; one for each side. For other sizes, you only need one coil unit.**
