ISOCOOL Side Sleeper Pillow

While the gusset shape is specifically engineered for side sleepers to maintain spinal alignment, this pillow is also suitable for back sleepers. Its medium firmness provides enough support for back resting, though it is not recommended for stomach sleepers due to the loft height.

The pillow comes with a removable 300-thread count cotton cover that is machine washable, making it easy to keep fresh. The foam core itself should not be machine washed; spot clean only if necessary.

The gusset refers to the side panel of the pillow, which creates a box-like structure rather than a tapered edge. This design allows the pillow to maintain a consistent height from edge to edge, filling the gap between your shoulder and neck to reduce pressure points while side sleeping.

The foam core offers a medium level of firmness, which is designed to balance cushioning with stability. It is not adjustable, meaning you cannot remove or add fill to change the loft or density.

The pillow features a 300-thread count cotton cover, which is naturally breathable and helps promote airflow. While it is not a cooling gel pillow, the cotton material is significantly more breathable than synthetic alternatives.
