Yes!!
I've always thought so as well!
Altho I agree that losing weight and eating correct are big steps towards alleviating GERD.... I would also say that elevating my bed head abt 6 inches has been the best thing I ever done as well
Matter of fact.... I find it more comfortable to sleep this way with GERD or without.
Problem is... like you said... no one makes a GOOD bed frame that allows easy adjustment of the elevation. I envision a space frame type bed..... made of aluminum tubing.... kind of hi-tech looking. But very strong and light that can be adjusted in elevation and also broken down and easily taken with you on trips such as vacations.
Kind of like a very hi-tech "cot" if you will
I'm not a designer... but wish I were....as id design something myself.
