Comfort Mats Sound Trap
The Comfort Mats Sound Trap is a premium acoustic foam block engineered to silence the hard-to-reach technical cavities in your vehicle’s A, B, C, and D pillars. Where traditional sound deadening mats simply can’t fit, Sound Trap steps in — compressing for easy installation and then expanding back to its original shape within seconds to completely seal off noise-leaking gaps.
Key Features
- Shape Memory Foam: Simply squeeze, insert into any technical hole or pillar cavity, and watch it expand to fill the space perfectly — no adhesives or tools required.
- Targeted Noise Cancellation: Specifically designed to block road, wind, and structural noise entering through technical holes in A, B, C, and D pillars.
- Water-Resistant Side: One face of each block is moisture-resistant, ensuring long-term durability when installed against body panels prone to condensation or water ingress.
- Easy Installation: No cutting, no mess — the self-expanding design makes installation fast and foolproof even in the tightest spaces.
