PRP Seats A4108-POR900 RST Rear Suspension Seat for Polaris RZR 4 800 & 900

The PRP Seats RST Rear Suspension Seat (A4108-POR900) is a purpose-built rear seat designed for the 4-seat Polaris RZR 4 800 and RZR 4 900. Engineered for all-day comfort on the trail, the RST combines a vinyl-coated nylon suspension liner with dual-density foam to absorb impacts and minimize rider fatigue over long stints in the dirt or dunes.

The RST's design features lower side bolstering compared to traditional bucket seats, making it easy to enter and exit the RZR quickly. A contoured bowl section at the hip provides lateral support without the overly tight feeling of a high-bolster seat, while the shoulder area opens up for a spacious, accommodating fit — ideal for larger riders or anyone who prefers a less "hugging" seat profile. The sides flatten toward the front of the seat, giving it the feel of an extra-wide seat while remaining standard width — making it compatible with 4-door RZR cabins that cannot accommodate wider aftermarket seats.

The wide headrest opening and integrated side loops are designed to route and retain a harness securely. A standard sand and mud drain keeps debris from accumulating in the seat. This rear-specific seat is 3 inches shorter in seat depth than its front counterpart, maximizing legroom for rear passengers in 4-door RZR models, and bolts directly into the rear mounting positions.
