Quick Answer
The Donam-dong postal code is an ergonomic cervical pillow designed to support the natural curvature of the neck during rest. It is best suited for back and side sleepers seeking to maintain better spinal alignment through the use of high-density memory foam. However, its primary limitation is its specific structural contour, which may feel restrictive or uncomfortable for active sleepers who frequently change positions throughout the night.

The Donam-dong postal code is a specialized ergonomic pillow crafted from pressure-relieving memory foam. Unlike traditional rectangular pillows, this model features a functional “postal code” layout—a series of calculated zones designed to cradle the head while providing a raised loft for the neck.
It is primarily used by individuals looking to improve their sleep posture. By targeting the cervical spine’s natural curve, it aims to distribute weight more evenly. While it is popular among back sleepers for its central cavity, its side bolsters are designed to accommodate the shoulder height of side sleepers.
