Best Mattresses for Acid Reflux & GERD
Reflux is gravity-dependent — every overnight episode resolves faster when the esophagus sits 6–8 inches above the stomach. These 8 mattresses are adjustable-base compatible and hold their shape under sustained incline.

Wedge Pillow vs. Adjustable Base vs. Mattress Tilt
- Wedge pillow ($40–$120): cheapest, but rolls off at night and only elevates the head, kinking the esophagus.
- Bed risers under the head legs ($25): elevates the entire torso, but a flat mattress on a tilt slides bedding and the sleeper toward the foot.
- Adjustable base ($800–$2,400): gold standard — elevates from the hip pivot, preserves mattress integrity, and lets you lower flat when reflux is dormant.
- Mattress matters as much as the base: cheap foam compresses unevenly under sustained incline, voiding warranties and undoing the gravity benefit within 12–18 months.
