Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

The most perfect pillow!!!
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I have spent so much money over the years, 14 years to be exact in trying to find the perfect pillow. I have finally achieved that by buying this amazing memory foam pillow. What I've been searching for is this exact pillow. It's firm, but yet soft and so comfortable. It forms to your head and shoulders. I don't constantly wake up in the middle of the night to fluff my pillow, this pillow stays fluffed throughout the night. The price is a steal and bcuz it's been so hard to find this perfect pillow that I first bought 1 set to try it out and ordered another set right away. I have total of 4 of this amazing pillow. Thank God literally, I am finally done buying pillows. Thank you Amazon for the best purchase ever!!!!

Feels amazing
Color: White, Size: Standard (1 Pack)
This pillow has completely transformed my sleep! From the very first night, I noticed how comfortable and supportive it feels. The filling is just right — not too firm, not too soft — and it cradles my head and neck perfectly, helping me wake up without stiffness or discomfort.
I’ve tried several pillows over the years, but this one stands out for both comfort and quality. It stays fluffy throughout the night and doesn’t flatten like some others do. The cover is soft and breathable, which keeps things cool and comfortable even on warmer nights.
Overall, this pillow offers excellent comfort and support at a great price. Whether you’re a side, back, or stomach sleeper, I’d highly recommend giving this one a try — it’s helped improve my sleep and I’m very happy with it!

Affordable, but lower quality than I expected
Color: White, Size: Queen (2 Pack), Color: White, Size: Queen (2 Pack)
I had an adjustable pillow that came with white, soft, shredded foam with fibers. It was super comfortable. When it came time to replace that one, I specifically chose this OAISZ pillow based on the listing photos that show this has white, soft, shredded foam with fibers. Unfortunately, what I received was low quality blue foam chunks with no fibers. The foam has thick, stiff edges that I can feel. While I was filling the pillow with the foam chunks, I noticed the outer pillowcase had stitching unraveling. The pillowcase feels cool at first, but then it heats up. Overall, these are affordable pillows for a set of two. However, they are low quality. The pillow is comfortable enough to sleep on, but I’m disappointed that the filling is not what is shown in the listing photo.
UPDATE: The seller reached out to me after I left the above review and proactively offered a refund which I appreciate. I have revised from 3 stars to 4 stars as a result. The product was not for me, but the customer service was outstanding.
