The Taylor Made Corner Dock Cushion features a hybrid construction with soft compressible foam where you want it and tough high-density foam where you need it. The inner core of this bumper is a lower density EVA foam (2.8 lbs. per cubic foot) and the outer (front and back) pieces are tougher, higher density PE foam (8.7 pcf). The UV-protected foam material is maintenance-free, non-marring, and provides superior cushioning from impact.
