Really good pillows
Number of Items: 1, Number of Items: 1
I’ve been using this pillow for a while now and it’s honestly one of the most comfortable pillows I’ve tried. It has a soft, cloud-like feel but still gives enough support for my neck and shoulders. I’m a side sleeper and it keeps its shape well through the night. The material feels high quality, and it doesn’t go flat like cheaper pillows. Definitely improved my sleep quality and worth the purchase.

Soft AND supportive
Number of Items: 1
I knew I needed a very soft pillow - all the foam pillows I had bought recently to try to upgrade our home pilllow selection seemed ok to the touch but were still too firm once I tried them out, but recently I also had some neck pain that needed some gentle support and the old old foam pillow I had that was so very soft was losing its supportive qualities and the pain wasn’t getting better. This one seemed by description to fit the bill- very soft by the company’s own definition but also with support. I’m happy to report this is exactly as advertised- the softest foam pillow I’ve tried out of the box but also good support. Pain has improved since I started using this pillow. I would buy more if we need more pillows, it’s perfect for me and I think would be comfortable for most people. I think you just need to figure out how firm you need your pillow and also height preference . I’m an all over sleeper -back, side, even belly sometimes, so it’s fine for me, but it is a little taller compared to other pillows I’ve bought recently. I didn’t compare/try other prominent pillow brands, mostly my experience is Ikea (my daughter uses a very flat and nice foam pillow from them that is even a little pricier than this one and it works well for her), and whatever brands happen to be available at target and Costco. This price point for a name brand is reasonable, I think; I was looking at other brands way over $100, and I was willing to spend that much for something that would work long term, so this one working was great. Also, this definitely does not have any cooling effect technology, which is fine by me, but something to consider if you do like cool pillows. (Although, PSA: I recently had to throw away older foam pillows that had those cooling gel panels because the gel panels started disintegrating into sticky ooze; gross and had to throw away whole pillow because couldn’t dissociate from rest of the pillow. Sad cuz the foam part of those pillows were fine.) Anyway, if you like softer pillows but want good support, this one works well and is worth trying!!

Flatter than a regular pillow but nice and soft
Number of Items: 1
Is it softer than a typical memory foam pillow? Yes. But it’s also a lot flatter. I don’t find this pillow rebounds very well. It’s good for stomach sleepers but not so much for side sleepers. I’m a 2/3 of the night side sleeper so it’s unfortunately not my magic pillow.

Best pillow for my neck pain.
Number of Items: 1
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
Number of Items: 1
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. 😊
