Baby won't eat anywhere but in bed

ch
So the past few days my baby refuses to eat anywhere unless it's in bed laying down. I don't get it. She's breastfed only. Everytime I try to feed her anywhere else she fussed and arches her back and will refuse to eat, won't even latch. So I take her up to the bedroom and she eats fine doesn't fuss or anything. To me this sounds like the opposite of reflux so idk what the heck is going on
