Help Needed: Move Solid Wood Sideboard and Mirror Upstairs

Looking for assistance with moving a solid wood sideboard and a three-foot mirror from my SUV into my home. The sideboard is 50" wide, 36" high, and 22" deep. The task involves carrying these items up a flight of stairs. The SUV is parked right outside the door, so no additional vehicle is required. Unsure if two movers are necessary, please assess based on the item descriptions.
