Edge class "double sofa bed"

[Mark_UK]

Am looking at booking an Infinite Veranda on Apex for 3 adults. The cabin has an icon indicating a "double sofa bed". Is this different to the trundle bed? 

 

I've searched around and can't seem to find any specific information as to what the double sofa bed is. 

 

Thanks!

I had been trying to figure this out as well, prior to an Edge sailing the end of June. It was listed as the ‘double sofa bed’ and it is the trundle bed, BUT if there are three of you I think it will work well. They pull the mattress out from lower bed and place in on top of couch and it becomes a comfortable twin bed.  An advantage of this style vs. the pullout sleeper sofas is more space when in use as a bed. Here is the link for my earlier post. My last post includes picture of the couch in bed mode and there is also another link in one of the responses showing the trundle as four-person setup.
