Is it possible to access the instructions before i purchase so that I can check the dimensions are right for my purposes?

The legs are a set height , or can we adjust them, or order longer ones, so that the bed can be be set to rest higher off the ground? Reason being, that a couch/foam bench, will used in front of it, when it’s up, so would like to just move the cushions, and have the bed sit above the flattened couch, rather than having to move the couch out of the way, every time the bed is pulled down . Or is there a separate kit for when making a Murphy bed when it’s lowered over a couch? Thanks
