A pillow is a rectangular cushion, which is used by all of us for comfort, therapy, or decoration. It keeps our head aligned with the neck and backbone during sleep. 

Some common types of pillows are Down Pillows, Down Alternative Pillows, Feather Pillows, Cotton Pillows, Wool Pillows, Latex Foam Pillows, and Memory Foam Pillows.   

• Down pillows are made from the soft fibers. They are light-weighted, moldable, durable, soft and cushiony. They are best for side, back, and stomach sleepers.
• Down alternative pillows are made synthetic fibers such as polyester or poly fill. They are not as warm, plush, or durable as down, but they are cheaper and easy to maintain.
• Feather pillows are made of a traditional filling that provides support without losing shape. They are more comfortable and supportive than down pillows. However, many feather pillows are also filled with a small amount of down, which is allergic to some people.
• Cotton pillows are made of classic pillow material that has specific advantages, especially for people who are allergic to synthetic materials. If you want pillows that can regulate temperature well, then cotton fabric is the best pillow for you.
• Wool pillow is a highly breathable, fluffy, and soft. It is available in 100-percent wool or blended with other fills. Wool pillows are not as popular as other types, because they are more costly and can only be dry-cleaned.
• Latex foam pillow is also soft, breathable, and supportive. It provides excellent pressure-point relief. It is also resistant to dust mites, mold, and mildew thus keep your sleep environment clean. 
• Memory foam pillows are extremely popular because they are a good choice for all sleeping positions.
