My doctor recommended I prop up the head of my bed 4-6 inches to prevent acid reflux at night, using bricks, wooden blocks, or special made bed risers like these
That might work fine on a normal bed frame with 4 legs, but I have a select comfort air mattress which has it own modular plastic frame which has 6 legs not 4, and the long piece of the side is 2 pieces joined together instead of one long piece. If I prop up the head, the 2 legs in the middle will be floating in midair and probably bend the frame.
Here is a diagram I made of what it looks like
Here is a picture of someone assembling a frame
Is there anyone here who can figure out a way to also support the legs in the middle so it wont bend the frame over time?
