my husband and i bought us each a mypillow. my neck started hurting a few months after i washed it, for 10 weeks i though i was going to die from such pain.
i was ready to buy another pillow when my husband said to not use a pillowcase on it. i tried no pillowcase and what a difference it made! i have no more neck pain and i sleep better.
i think the issue with the mypillow is a pillowcase stops the filling from branching out and doing its job. of course now i have no way to keep the pillow covered but at least i can use it after spending good money.
Reason of review: got the issue resolved.
