Some people snore more or have more obstructive events while lying on their back. That makes positional strategies relevant, but the evidence does not justify selling a generic pillow as a treatment for every breathing problem.

What reviews have found

A 2024 systematic review reported that positional approaches and head-of-bed elevation may reduce snoring, while noting discomfort, tolerance problems and a need for better comparative studies. Reviews of positional obstructive sleep apnoea show reductions in time spent supine and apnoea-hypopnoea index for selected patients. However, a Cochrane review found that CPAP produced a greater reduction in AHI than positional therapy, with low-certainty evidence for that comparison.

What this means in practice

• A wedge can create an elevated position for comfort, reading or sleep.
• Side-sleep positioning may help selected people whose breathing events are position-dependent.
• Long-term comfort and adherence can be limiting.
• A retail pillow cannot determine whether someone has positional OSA or whether positional therapy is appropriate.

Red flags for assessment

Seek medical advice for loud habitual snoring plus witnessed breathing pauses, gasping or choking, marked daytime sleepiness, morning headaches, high blood pressure or impaired concentration. Do not stop CPAP or another prescribed treatment because a pillow feels helpful.
