Comfy pillows! Excellent deal
Color: White, Size: Queen(2Pack)
I received these pillows shrink-wrapped flat as a pancake. But I've received other things this way including whole king-sized mattresses and they always puff up to normal size once you pop them out of the plastic wrap.
These pillows puffed up pretty quickly. I did shake them and pound on them a little off and on for about an hour before slipping some pillow cases onto them. Their not super fluffy but not too flat. I like that their soft yet have a little support. My husband really likes his too. We both get a good sleep on these. I'm a side sleeper so it's really comfy for me to have some "squishiness" like these have.
As far as quality goes, these are nicely stitched and the fabric feels soft. The pillows are rather lightweight and I won't know how durable these are until we've used them for a while.

Impressive Set of 4 King Pillows – Comfort Meets Quality

Impressive Set of 4 King Pillows – Comfort Meets Quality
I recently upgraded to this 4-pack of king-size pillows (20 x 36 inches), and they’ve been a fantastic addition to the bedroom. Certified by Oeko-Tex, they’re suitable for all sleep positions—whether you’re a side sleeper like me or prefer your back or stomach.
The feel strikes a perfect balance between soft and supportive. The microfiber filling cushions your head and neck without going flat, so I wake up without the usual stiffness. They bounce back quickly after use and keep their shape well—just give them a quick fluff when needed, and they’re good to go. They do need about a day to fully expand once unboxed, but that’s expected.
The design also deserves a mention. The subtle stripe pattern gives the pillows a clean, upscale look—definitely not your average basic pillow. They’d make a solid gift, too.
Cleaning is easy: toss them in the washer on a gentle cycle with cold water, then either air dry or tumble on low. No hassle.
If you’re looking for a dependable set of king-size pillows that feel great and look sharp, these are worth it.
I also took a picture of it next to a standard pillow so that you could see the difference in the size from King to standard. Hope that helps, overall definitely buy these pillows if you are hesitant there is no need to be, these pillows are perfect in my opinion

High End feel.
Color: White, Size: Queen (Pack of 4)
I bought this because I needed to replace old pillows. After using it for a few day I liked that they stayed fluffy and cool all night. My guests loved them too! The quality feels high end. I would recommend it for anyone that likes high end feel without the the high end price.

Comfortable pillows
Color: White, Size: King (Pack of 2)
I bought the king size and they are like a small body pillow. They’re soft n squishy which I like but yet provide the right amount of support. I’ve bought these twice and the 2nd set seemed a little less filled than the first but still comfortable. I would buy again.
