hope this helps
we have a hall that dont have stage area or anything like that and we spent months designing things but realised weight was a major problem (not me on my own haha )
so anyway i searched ebay for the word platform and came up with these
http://www.ebay.co.uk/itm/Builders-H...item3cc025807e
these are fantastic and light weight and will carry two average size people
and are a perfect height and within guidelines for insurance / health safety
hope this helps
