Of course comfortable is a personal thing. We had an "L" sofa in our rig and we hated it for a variety of reasons. We sat in the brand you are looking at and although it was comfortable from the seat part, the back of the sofa was still sooooo low that there was no support. The other thing for me, not so much for wife, is that the cushions were so short I felt like half of my rear end hung off the front of the seat.
We ended up going with a Lazyboy sofa that had recliners on both ends. 3 months before this purchase we replaced the euro recliner (horrible as well) with a Lazyboy recliner. Now that we've had the new furniture, so glad we did it.
