Find answers to memory foam care instructions, sleep positions, and cleaning guidelines for your Dr.Prime cervical pillow.

The D stands for density — pounds per cubic foot. Most budget and mid range memory foam pillows use 40D or 50D foam. 60D is higher density, meaning more foam material per unit of space. In practical terms this means better orthopedic support, better shape retention over time, and a pillow that lasts significantly longer. Low density foam compresses and flattens within months. 60D foam holds its shape for years with proper care.
