At the top of the open riser staircase, an oak trim piece is added flush to the stringer. This creates a neat pocket for the carpet to tuck underneath, avoiding the need for a carpeted nosing, which can look bulky and wear out quickly. Additionally, a matching piece of oak wood trim is installed on the riser itself at the top, replacing what would typically be drywall. This choice significantly improves the durability of the riser, especially in a high-traffic area, and maintains a consistent aesthetic with the rest of the wooden stair components.
