fix a metal bed

dipsy

Hi

have a bed about 3 years old, bought from Benson Beds

has two middle supports one at either end of the bed frame, about 1/2 foot from the outer frame of the bed, anyway since removing carpet and having wooden flooring the bed has walked, and within 3 weeks the supports have ended up like a baby giraffe learning to walk and one snapped off last night at 12am whilst trying to straighten it....... so partner put the snapped off leg in the middle of the bed and it held so far...

question is how do I go about sorting this out, will I believe need at least 3 supports 2 either end and one in middle, whats the best way to do this?

also anybody know where I can get leg protector /castor cups from with holes in so we can screw them to the floor and drop the bed in them to stop the bed walking

thanks
