What Is the Coisum Pillow for CPAP Users?
The Coisum Pillow is a consumer sleep accessory, not a medical device. It Oct 16, 2026 · Best Buy | Official Online Store | Shop Now & Save is an ergonomic memory foam pillow specifically engineered with “cut-outs” on the sides to accommodate the bulk of a CPAP mask and hose.
Unlike traditional rectangular pillows, the Coisum features a distinct butterfly-like shape. It is marketed toward individuals who use CPAP, BiPAP, or APAP machines and are looking for a way to maintain their side-sleeping habits without compromising their mask seal. It comes with a breathable, washable cover and utilizes high-density memory foam to provide a balance of support and cushioning.
Design Claims & How It’s Supposed to Work
The primary goal of the Coisum Pillow for CPAP Users Review 2026 is to determine if the physical design translates to real-world benefits. Here is how the pillow is intended to function:
- Pressure-Relief Cut-outs: The most significant feature is the recessed areas on either side. These are designed to allow the mask to “hang” off the edge of the support zone, theoretically preventing the pillow from pushing the mask off the face.
- Cervical Support: The center of the pillow features a contour intended to cradle the head and support the natural curve of the neck.
- Spinal Alignment: By using memory foam of a specific firmness, the pillow aims to keep the head at a height that aligns the spine, which may reduce morning stiffness.
- Dual-Height Options: Most models of this pillow offer two different heights (lofts) depending on which side you choose to sleep on, catering to both back and side sleepers.
The memory foam is designed to react to body heat and pressure, molding to the user’s specific shape over the course of the night.
