I've tried so so many pillows to relieve my neck pain at night and this one is the first pillow that has actually worked. I was skeptical at first as this pillow is heavy and dense but one night and I was hooked. I couldn't believe I found a pillow that actually not only was comfortable but also relieved my neck strain. It's worth the cost to now be able to wake up without pain.

Tempur-Cloud Pillow

My daughter has been struggling to find a good pillow that does not hurt her ears. She is a tummy sleeper, as am I. I have also been struggling to find the perfect pillow. I heard about Tempur pillows and thought it a good idea to buy my daughter a pillow for her birthday. It arrived last night. She tried it out during the night. When she woke up this morning, the first thing she said was that the pillow is amazing. It was a good night for her. She said it felt like sleeping on a marshmallow - soft enough to not hurt her ears but firm enough to support her neck. The pillow is very comfortable. 😊

This pillow flattens so much I’m not sure if it’s a legit tempur pedic or not. I bought one previously from Tempur Pedic store and the quality is better plus is more supportive. This one is meh . I gave it to my husband, he doesn’t care

Get one but use it on a medium firm mattress, not a firm one.

Number of Items: 1

You need a mattress that is medium firmness to use this wonderful pillow. It gives perfect neck support and I can sleep on all 4 sides with it. My neck/head pain quit first night used it. On a firm mattress it feels too hard and awkwardly cradle l es my head.
