Abstract: A portable seat and platform support includes a shaft with a base mounted to its lower end to position the shaft to a generally vertical orientation. A removable platform can be attached to the upper end of the shaft, and a seat assembly is supported by a fastener assembly along the shaft for independent rotation about the shaft axis. The seat assembly includes a collar slidably attached to the shaft, a seat supported by the collar, and a bearing on the collar. The fastener assembly includes an adjustment device to support the collar at a selected location along the shaft axis, and a bearing portion supported by the adjustment device and journaled to the bearing on the collar.

Abstract: A gun rest has a first support mounted to a base and a support arm pivotally mounted to the first support. A platform for supporting a firearm barrel is mounted to the support arm. A manually-operable adjustment assembly couples the first support to the support arm to fixedly adjust an angular position of the platform relative to the base. The adjustment assembly has first and second fasteners pivotally mounted to the first support and to the support arm, and a manually-operable coupler threaded to the fasteners to selectively alter a distance between the first and second fasteners. A second platform mounted to the base supports a firearm stock, and an optional third platform is removably attachable to the support arm to support a pistol grip and hand of a user.
