We find the eurochair to be....adequate and comfortable. The arms sloping downward are not as comfortable to my taste as straight arms. The reclining sofa is also pretty nifty. And, it makes a decent and acceptable bed.
Lets face it: putting all this in a coach less than eight feet wide requires some pretty unique design and every piece of furniture must be comfortable, affordable and fit the limited space. Also, they must be multi-functional. SO....everything is a compromise. And everyone has their own personal tastes, particularly when it comes to comfort and usability.
The most comfortable seats for me personally in any RV were the Flexsteels in our first Roadtrek twenty years ago. Or, maybe my back was twenty years younger????
