I have the fold out sofa bed with the air mattress in my Sightseer 35J. It sets up nicely, but as soon as anybody gets on it and moves around any, the bottom third starts to fold up. This is the part with the tubular legs that flip out to support it and it's supposed to fold back toward the sofa as part of stowing it, but it should stay straight when in use. I don't see any kind of locking mechanism to hold it flat. Is this the nature of the beast or is it just mine? What do you do to keep yours deployed correctly when in use?
Thanks,
John
