Standard Comforter. Thin Scratchy Sheets
Color: Dark Green, Size: Queen
This is an ok set for the price. I’m mostly using the comforter for a guest room. It’s a light-medium thickness. The color and size are true to description.
The sheets that come with the set are very thin and not as soft as the comforter.

Comforter is nice, sheets are alright. Color is true!
Color: Burnt Orange, Size: Queen
This is a decent comforter set. The actual comforter isn’t too heavy, and would be perfect spring through fall in the Midwest. It’s a true queen size fit and the burnt orange color looks as it does in the photos. I ordered these before it mentioned they’re polyester. They definitely don’t feel as breathable as cotton sheets but as far polyester goes, they feel soft. The sheets wrinkle easily but the comforter feels durable. If you’re looking for an affordable sheet set and you’re cool with polyester, this is a good option.
Also of note is that 2 of the pillow cases have a little extra fabric on the outer rim to look more “decorative.”

Comfortable and Attractive Bedding Set That Offers Great Value
Color: Pink, Size: Queen
This queen bedding set is a nice combination of comfort and style. The pink color looks beautiful, and the textured comforter gives the bed a cozy, modern appearance. The sheets feel soft and comfortable, while the comforter is lightweight yet provides enough warmth for a restful night’s sleep. I appreciate that the set includes everything needed for a complete bedding setup, making it a convenient option. It’s also easy to care for and holds its appearance well after washing. While it may not have the feel of a premium luxury set, for the price it’s not bad at all and offers solid value. Overall, it’s a great choice for anyone looking for an affordable and attractive bedding set.

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.
