Would buy again
Color: White, Size: Standard (Pack of 2)
This is a good pillow if you like them firm and thin. I let them sit out for 2 days (per instructions).
After having them a week, they've perked up and became more full. I guess they just need time after being in the air. They are softer now but your head doesn't sink thru it. They are actually nice and soft to the touch as well.

On the thin side....
Color: White, Size: King (Pack of 2)
These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.
Color: White, Size: Standard (Pack of 2)
These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.

Great Mattress for Everyday Use
Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin, Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin
I’ve been sleeping on this mattress for a few days now, and I honestly couldn’t be happier with it. It has that wonderfully soft, memory foam feel that I love, but it also provides just the right amount of support to keep my body comfortable all night long. I usually sleep on my side, and sometimes on my back, and I find that it feels great in both positions—no more waking up with a sore back, which is such a relief.
What really surprised me is how cool it stays during the night. I’ve used memory foam mattresses before that made me sweat, but this one has a noticeable cooling effect that actually works better than I expected. It stays comfortable all night, no matter how much I toss and turn. Plus, it absorbs movement really well, so if my partner shifts around or I move in my sleep, it doesn’t disturb me at all.
Setting it up was super easy—the mattress expanded quickly after I took it out of the box. There was a small foam smell at first, but it vanished pretty fast. Overall, it’s comfortable, supportive, and feels like a great value. If you’re looking for a mattress that strikes a good balance between softness and support, I’d definitely recommend giving this one a try.

Comfortable, Supportive, and Sleeps Cool
Item Firmness Description: Medium Firm, Item Thickness: 10.0 Inches, Size: Queen (U.S. Standard)
This queen mattress is very comfortable and offers a great balance of softness and support. It is medium-firm and works well for relieving pressure on the back, shoulders, and hips while still feeling supportive throughout the night. The cooling feature helps keep the mattress comfortable and fresh, especially for warmer sleepers. It arrived neatly packed in a box and expanded quickly after opening with very little odor. I also appreciate that it’s certified, which gives extra peace of mind about the materials. Overall, a high-quality mattress that delivers great comfort and value for the price.
