I have a "sunrise spa electric couch" , but with the head adjustable only. I bought mine from a private sale around 10 years ago and it is fab.
Natural Living sell them and also do the 3 section split couch called "seers 3 section couch".
Price wise 3 section is so much more money , is it essential?
REM are a very good make, I don't think you will be dissapointed. the cushioning on them is excellent . When I worked in the salon, my boss always said they were the rolls royce of couches!!
It is gorgeous, simple yet luxurious. You will get years and years of use out of it.
