Key Advantages
Why Choose Airweave Advanced Mattress
- Airfiber core is roughly 90 percent air — by a wide margin the coolest-running mattress we measure
- The core blocks are genuinely washable with water, which is unique in the category
- Firmness is reconfigurable at home by rearranging blocks, and MattressFit recommends a layout from two photos
Why Choose King Koil FLOWT
- Spiral coil system keeps lateral airflow open — excellent heat dissipation
- Cooling gel comfort layers stay neutral through the night
- Responsive medium feel suits combination sleepers
