1.It is a good habit to wash the pillowcase often, especially when it is new or after using 1-2weeks.

2.YOU MAY NEED TO ADJUST TO THE PILLOW OVER SEVERAL WEEKS. Immediate overuse may increase neck pain. Most users who slowly ease their way into orthopedic correction achieve the best results. Alternate between Elviros and the current pillow while your body adjusts.

3.Due to the inherent characteristics of the memory foam material, the received pillow core will change seasonally, and the hardness and softness will also change appropriately, but it will not affect normal use.

4.This pillow is medium soft and tough. If you usually sleep with a pillow that is too soft or too hard, please buy with caution

5.Please don’t expose the pillow in the sun in summer or wash the pillow core. Sun exposure and water can destroy the structure of the memory foam and influence the hardness of this pillow
