FOR SEAT MODEL: M90 - M2004 - M2008 - M2000 - M2010 - M2011 - M2003  The step riser is an excellent solution for increasing the seating height of spectators on the steps, when the seating height of the seat fixed directly to the step is insufficient. It is an effective technical proposal both to maintain the visibility curve and to comply with the EN 13200 standard, which recommends a minimum height of 400 mm and a maximum of 450 mm.  The possibility of inserting the riser in the same colour and material as the monocoque allows for an extremely solid, vandal-proof and aesthetically pleasing solution. Its versatility allows it to be compatible with various OMSI seats; it is completely ribbed on the inside. With the possibility of overlapping, it can raise the seat 100 mm from the step. It can be fixed in a variety of ways to meet the most stringent fixing requirements; OMSI seats placed on this riser system retain their vandal-proof characteristics, certified to EN 12727 level 4 strict.    Contact us
