ExpBedsure Contour Memory Foam Pillow Standard 24x13x4/3.5 inches @ Amazon

Breathable for Hot Sleepers: Ergonomic pillow has ventilation holes well distributed on the memory foam and on both sides to improve heat transfer and increase excellent breathability, very popular among hot sleepers compared with a conventional pillow.

Soft but Supportive: This sleeping pillow is composed of CertiPUR-US qualified soft memory foam and high resilience foam, so you get the right balance between soft and supportive

Fascinating Details of Ventilation Holes: Holes are large and dense in the middle of the cervical pillow to provide softness for back sleepers, while tiny and sparse all around makes it more supportive for side sleepers.

Aligns the Back and Neck: This contoured pillow fits the hollow space between the head and shoulders, assuring you a wonderful night's sleep.

This pillow is STANDARD 100 by OEKO TEX certified. This means the product satisfies the highest criterion of testing for harmful chemicals and has been found to be harmless for humans.

Bonus, Breathable Plus: Sleeping pillow's polyester cover mixed with 39% nylon fabric with air mesh design makes it more breathable and cooling. Machine wash the cover of the cervical pillow in cold water, separately; tumble dry low.
