Hi Sensei,
Thank you for looking into the L&P wall hugger. I called them as well but after 25 minutes of being on hold, I gave up.
This is the videoI watched comparing L&P Scape (5:48) vs Reverie (7:50) wall hugger.
However, I just found there is another video from the same guy on Scape2.0. He mentioned L&P made several changes and the wall hugger is no longer moves as much as the old model. (0:25)
It is too bad that they made this change. I don’t know if there are other make/models that might have a full wall hugger option but since they don’t list this information on the website, the only way to figure out is going to the showroom with a ruler 
For the adjustable bed, I’ve been to SleepShop which I got the link from Phoenix’s post on this page
For latex dunlop mattress, I’ve been to North Shore Linens and InBed Organics, both mentioned from Phoenix’s post. However, they do not sell adjustable bed.
I have more questions on latex mattress but I’ll post it somewhere else.
