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 comfortable memory foam body pillow
Size: Body(Pack of 1), Color: White, Size: Body(Pack of 1), Color: White
Homelab adjustable shredded memory foam pillow hugs to the curve of my body so comfortably at night. Since I’m a side way sleeper, it’s really nice to have a pillow to prop up my knee on the side.
The pillow arrives in a vacuum sealed bag, and it bounced into shape quickly. The pillow cover is made with a really nice material, it’s soft and thick and it stays cool. The shredded memory foam inside makes it so easy to adjust the firmness of the pillow. I think this pillow is made with high quality material and would recommend it to all the side sleepers.

Awesome pillow
Size: Body(Pack of 1), Color: White
So although the pillow is pictures as a head pillow, I actually use this as a body pillow because it's as long as one. That's fine by me because it's somewhat firm but gets soft as your body heat warms it up. I've been using it for a few weeks now and haven't noticed any bad misshaping or anything. It's shredded memory foam so like all shredded memory foam pillows you've got to fluff them a little.

Very soft, full, and versatile! Potential game changer for my bed!
Size: Body(Pack of 1), Color: White
I am so happy with this pillow! I have a really hard time getting comfortable in bed-especially with pillows-and I’ve struggled with sleep since childhood. But this pillow is so comfortable-it’s such a great, happy surprise! The material allows my head and neck to sink in, but with support! I’m not using it against my body, but instead, have it lying on top of and across the length of all my other pillows and almost magically, I can turn over without having to do a whole bunch of squishing and adjusting the pillows! It’s like it somehow balances itself exactly right. Years ago, I had a body pillow and used it to lie against, the length of my body-but using it as a full-length “top pillow,” instead, was such a good idea, I can’t believe it was mine! Really, super happy with this!
