Boat seats are typically mounted on pedestals that are attached to the floor with the help of specially designed bases. Pedestal bases touch and screw to the floor and surely, should be strong enough to withstand heavy weights and harsh marine environments. Some of them are threaded while others are not. The latter are also called standard. They are shorter and feature only the bushing. The former come with a deeper cup with the female threads under the plate. As part of seat pedestals, they have an ABYC rating. That makes determining the right components for various positions on the boat easier.
Depending on your needs and wants, you can choose from round, square, and rectangular base plates with different post diameters. They are made from different materials including aluminum, steel, PVC, and stainless steel and come in different finishes such as E-Coat, anodized, camo, black, and many others.
