Does anyone know where I can get shorter theater chairs? (as lower to the ground).

When you say theater chairs do you mean theater chairs or recliners? and what do you define as lower to the ground?

Try seatsandchairs.com for a variety of seating options including good used theater chairs.

If you're wanting to sit lower to the ground, the Repose E1000 Entertainment chairs are pretty neat. They may be a bit more than what you're looking for since they have built in speakers, tactile transducers, etc. But it might give you point of reference on another product search.
