Because they would be a padding of blankets and a rock. Lol. The Dalish are constantly moving around, they wouldn't have a fancy bed or throne.
Then I don't think they would have fancy drapes or windows, either

I've been reading you guys for some days, and I've really enjoyed all the thoughtful posts and opinions. I just saw the second scene in the romance, and I'm happy I know how the third one plays out, for I'm sure it would have left me very sad if I wasn't prepared.
I know a lot has been said already; just wanted to add how I love that, throughout the romance and in spite of the few content, you can see the different layers of Solas and how it influences the romance buildup. (From now on there will be spoilers, sorry I don't know how to put the spoiler tags on the tablet format) I romanced Cullen on my first paythrough, and it is a slow and progressive buildup up until the first kiss that is kind of the milestone when Cullen finally opens up and gives in. However with Solas you share that first kiss pretty early, very passionately, like something that floods out of a gate that bursts open but Solas needs to close hastily. Then it is this battle between "ancient Solas", who is passionate in his love and fierce in his hate (glimpses are also seen at the Orlesian ball and on his personal quest); and the controlled, cold and logical Solas with his mind fixed in mending his wrongs. I really like this feeling I'm having through the romance of reaching out to that blazing flame that Lavellan feels inside him, and sometimes being let in when Solas can't fight his feelings, and sometimes being shut out when he remembers the weight he has put over his shoulders. I agree with other comments I read, that should Solas let his feelings for Lavellan pour out entirely, he would forget his missions.
And now after my long random thoughts, back to lurking!
