The weight of the seating unit, including the total weights of the persons seated, acts upon the floor over which a retractable seating system runs. In addition, depending on the conditions of the floor, travel performance may be affected. Please give full consideration to these aspects when designing floors in your building.
Please ensure that there is no more than 2mm variation in the floor level across the area over which the seating unit will run or be stored.
Caution should be used in selecting floor finish. Please read the notes below.
Timber FloorAs flooring made with underlay cushioning may be greatly deformed during unit travel, such floor materials are not appropriate as a running surface.
CarpetPlease choose a carpet with minimal undulations. Install the carpet with strong adhesion between the floor material and foundations so that peeling or wrinkles do not form in sections run over by the unit. Ensure that the weave direction of the carpet and the travel direction of the unit are parallel to one another.
PVC sheetingInstall the sheeting with strong adhesion between the floor material and foundations so that peeling or wrinkles do not form in sections run over by the unit.
Most floor materials will experience some degree of depressions (running marks) due to localized concentrated load from theretractable seating system, and these depressions will remain on a semi-permanent basis.
If the seating unit is to run over a sprung sports floor, please perform work as shown in the above diagram as far as the storage area. In addition, please reinforce the area around the storage area to prevent the floor from sinking.
*At the request of customers, Kotobuki Seating performs evaluation testing on the floor materials to be used. Purpose-built equipment is able to recreate the conditions that occur when retractable seating system actually travels over a material to confirm the level of deformation that occurs in the floor material in advance. Please contact a Kotobuki Seating representative for more information.
It is best for the floor over which the retractable seating system runs to be free from any gap. If transitions are installed for unavoidable reasons, please set the levels the same as the building floor and when gaps are formed, make them no wider than 15mm. Removable guide rollers are placed before and after the transition sections if a travelling unit is specified.

A load distribution diagram can be created upon request. Please contact a Kotobuki Seating representative for details
*Other: When installing under-floor air vents, floor heating, power outlets, microphone jacks or other items in the building floor, please consult a Kotobuki Seating representative in each case.
