Our trailer (28 BHBE) has the same basic slide configuration, though I'm not sure about the measurements because ours has the U-shaped dinette, so it might be a little bigger.
Anyway, I was thinking about taking our Hide-a-bed out and dropping some of these in there:
And at about $70 each, the price is definitely right.
We also have the storage ottoman, so that would help with kicking our feet up. According to the website, I would have about 3-5 inches of extra space if I put them in the slide with the backs up against the window. However, they are light enough that I could easily slide one out and angle the other toward the TV if we wanted to have movie night. Or I could leave them in the slide if we just want to relax with a book or something.
Either way, for us, some kind of chair would be a definite improvement. We have plenty of bed space, so we'll never need to fold it down. And it's okay for sitting in to watch movies or read, but it's not great.
Anyway, DW doesn't want to make the change any time soon, but this is the best solution I've got going so far...
