Let the couch hunt begin now!

As we have moved to a bigger flat it is finally time to get ourselves a nice big couch so we can watch movies comfortably in the living room as well as to provide bigger comfort to our guests:) Until now we were using a humble version of a couch, extendable, quite uncomfortable but servings its purpose. Time for upgrade!
Hopefully we find what we are looking for. It will be a lot of testing today:)
I am trying to figure out how to use some empty space in the hallway. What is the point of having a huge hallway? Yes, it is spacious but it is a space you can't really utilize...the only option I can think of is to buy another "Malm" and place it to one which is already there but Ikea has decided to not produce any furniture in this particular colour that we have our "Malm" in...The other thing will be to move this dark brown in the living room but the rest of the furniture is in a lighter colour so it won't match... ajaja headache :) I wish I could use the help of a designer who would help me get the most out of our flat but dream on...now back to reality and off to a couch hunting adventure!
