I use standard pillows but analyze: should I use position-specific support? Map the position needs: back sleep needs neck support, side needs shoulder gap fill, stomach needs thin pillow. Calculate: if I used position-optimized pillows, would alignment and comfort improve? Show me the pillow prescription: this pillow for this position. Give me the implementation: these specific pillows for my primary position. Include: whether standard pillows are suboptimal for my position, what support I need, and specialized pillow types.
