When you are comfortable in your seat, your attention naturally focuses entirely on what is happening on stage. Telescopic grandstands / retractable seating. When you can offer your guests a comfortable seat with a good view of the stage, you entice them to come back again. When the chairs are on a retractable stand, you can also use the entire room floor area completely free of obstacles.
For consulting on theatre seating and telescopic grandstands for your theatre or venue, PBTA is the right company to turn to (including advice / design / tendering / procurement / quick scan).
