Quality maintained
Color: White, Size: Queen
A client I service has these. She said she got them YEARS ago at Macy’s. Each time I change her linens I admire them for their plumpness. I found the well worn name tag then ordered hoping the quality hadn’t fallen since “years ago.” As pillows differ for everyone, I have found MY comfort level with this pillow.

Good quality and soft, but not for everybody.
Color: White, Size: Queen, Color: White, Size: Queen
These pillows are super comfortable if you like thick, firm ones. I absolutely loved them, they feel high-quality and supportive, but they are very thick, and after a while, I started getting some neck pain. That said, over time they do soften up a bit and start to mold better to your body, which helps. I’d definitely recommend them for anyone who likes big, firm pillows, but they’re probably not the best choice for people who prefer something softer or lower.

Soft & support
Color: White, Size: Queen
These pillows are perfect! I was looking for a cushy, lower profile pillow for side sleeping. So soft, supportive and comfortable! I could not believe the high quality at such an affordable price! They are queen size, so I need to purchase new longer pillow cases.

Muy buenas y cómodas solo la tengo hace 2 días ojalá no se desinflan como otras que yo he comprado , pero si son comodisimas si en un mes se mantienen igual pienso comprar 2 mas They are very good and comfortable. I’ve only had them for two days—I really hope they don't go flat like others I've bought—but they truly are extremely comfortable. If they stay just like this after a month, I plan to buy two more.

Odd, but nice pillows...
Color: White, Size: Queen
These pillows are nice, but strange for me. ..I purchased 2 in queen-size. They are slightly longer than I prefer but doable..and have an odd soft yet firm texture. When you lay the head down ..it sinks into the pillow, but each side comes up. So you have these big sort of firm soft, fluffy pillow ends on each side of your face. If you're a side sleeper, you will automatically try to punch one of the ends down a bit, for the most part, that will be useless. So you will probably end up trying to angle it a bit so that you end up sort of sleeping on the corner sections. (This was for the queen size, for me. The standard may be better.) Also, there really no cool side. If you flip it..it might feel cool for about 2 seconds, but that's it. They are very nice pillows, but I just know I will be ordering something else in the future.
