Tried the pillow-fort trick my sister swears by and my back hated me for it
My sister kept telling me to build a little pillow nest on the couch instead of just lying flat on it, so I gave it a shot with 6 pillows from the guest bed. I propped my head up high like she does, and about 40 minutes in my neck started aching and I woke up stiff as a board. Turns out stacking them that tall pushes your chin to your chest and messes with your whole spine. I swapped to 2 flat ones under my head and one behind my knees, which felt way better. What's your pillow setup for a couch nap, flat or stacked?
