Thai Buddha statue in a seated, meditating pose.
The statue is in the Dhyana mudra, a hand gesture representing deep meditation and calm, with the hands resting in the lap.
The Buddha is seated in the half-lotus position, or ardha padmasana, with the right leg resting on the left. 
The style is likely Sukhothai Thai, which is recognizable by the flame finial on top of the head and the serene expression.
This specific pose is sometimes associated with the "Saturday Buddha," representing the time when the Naga King protected the meditating Buddha from heavy rain
