2025 M3 Mattress Chassis

The Bedgear M3 Performance Mattress is designed for sleepers who want a truly individualized sleep experience, not a one-feel-fits-all mattress. Its modular construction allows each side of the bed to be tailored independently, making it especially well suited for couples with different comfort preferences or sleepers whose needs change over time.

The defining feature of the M3 is its customizable support system with independent coil units. Each side of the mattress uses a separate coil system that can be paired with different firmness levels, allowing two sleepers to fine-tune their own support without compromise. This modular design isn’t about initial comfort alone—it also allows components to be adjusted or replaced over time, extending the usable life of the mattress and preserving consistent support.

Another key strength of the M3 is its performance-driven approach to temperature regulation. Bedgear designs the mattress to promote airflow throughout the entire build, helping heat move away from the body rather than trapping it. For sleepers who want even more aggressive cooling, the Night Ice cover variant takes this a step further by incorporating advanced cooling materials designed to feel cool to the touch and actively dissipate heat, making it an excellent option for hot sleepers or those in warmer environments.

**NOTE: This is NOT a complete mattress. You will need to purchase M3 Coils to complete your mattress. For any queen or king configuration, you need TWO coil units; one for each side. For any other sizes, you only need one coil unit.**
