Just had a quick look at the photos of the rig and it has a similar layout to our first Cougar with the bed going north/south. We found this a nightmare to try to make the bed. Apart from having to pull the mattress down in order to get the bottom sheet on, once you have a couple of sheets and a blanket or two and then the duvet or bedcover there is very little room for them between the wardrobes and the mattress. We got so frustrated with it that we ended up trading that 5er in for the Cougar 291RLS which has an east/west bed with the bed head in the slide. Much easier to make the bed and room for blankets and duvets between the walls and mattress.
Those armchairs look heavy so keep in mind that one or both of them may have to be moved every time you want to travel and have to put your slide in.
Otherwise the layout of the living area is identical to the 291 and we love it.
Cheers
