amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!

These are very thick pillows.
Item Package Quantity: 2, Size: Queen
Exactly as advertised. They are very firm and very thick. They're too thick for me to be able to use as bed pillows. However, they seem to work pretty well as cushions in my papasan chair on top of its normal cushion also work very well as decorative pillows.
I'm still giving them four stars because they're exactly as advertised and they seem well made. My only complaint is that they're just too thick. And that's definitely not the fault of the pillows or the pillow maker.

Lightweight, very smooth and comfortable comforter sheet set an a very attractive price
Color: Ivory, Size: Queen, Color: Ivory, Size: Queen
Such a well priced, attractive bed in a bag (comforter and sheet set) with the most lightweight comforter I have ever come across that is not a down comforter. This one is filled with 100% polyester with a 100% microfiber exterior. The sheets are called microfiber, which I am sometimes not a fan of as sometimes they feel too stretchy and hot. However, these feel good, and almost more like a smooth percale. It’s nice to the touch. Color is attractive in a clean ivory color. Going back to the comforter, I love the lightness of natural down, but somehow I have developed a sensitivity to the feathers which make me sneeze. This one can easily be thrown into the washer and dryer and feels equivalently light as my down comforters. It weighs in at slightly over a pound (though I could only carry it onto the scale) and I absolutely love the lightness of it. I did wash it in the washer and dried it in a dryer on normal heat. Came out with no wrinkles and very fluffy. Five stars!

Nice Comforter, Thin Sheets
Color: Blue, Size: Queen, Color: Blue, Size: Queen
I bought this comforter set for my guest bedroom, and the price was great. It’s really pretty and fits the bed perfectly. It includes a comforter, a sheet set with pillowcases, and two pillow shams. It arrived vacuum-sealed, when I opened it, I was impressed by how soft it felt—just right for a comforter. It seems like it will be warm yet cooling at the same time, and I love its thickness. The only downside was the sheet set. While the comforter is fluffy and cozy, the sheets felt cheap—very thin—and I prefer them thicker. They’re labeled 100% polyester but are just too thin for my taste. If you’re not picky about sheets, this set would be perfect. They are soft, just not thick enough. Overall, I really like the comforter, but I’ll use my own sheets because of the thinness of the included ones. I would have given it five, but the sheets bring it down to four.
