How to put bed down and sleep in it?

[cloudstar69]

Trying to put down a bed "Gilt Blackwood Coffin" with ID = 8000059 then sleep in it and pick it back up

I put it down on my own first then looked up the X, Y, Z and turnAngle

var CoffinDoodad = getDoodads().Where(x => x.name.Contains("Gilt Blackwood Coffin") && x.dist(me)<30).OrderBy(x => x.distNoZ(me)).ToList()[0];
double xPos = CoffinDoodad.X, yPos = CoffinDoodad.Y, zPos = CoffinDoodad.Z, Rot = CoffinDoodad.turnAngle;

But then when I try to make the bot put the bed down in same way:

UseItem(8000059, xPos, yPos, zPos, 0, false, Rot)

It returns error: InvalidParam

Anyone know what I am doing wrong?
