Soft and cozy, sizing seems a bit inconsistent
Size: Queen (90x90 Inch), Color: Sage Green
I actually ordered two of these blankets in two different colors. We had urgent need to add a bed with all new bedding (medical reasons), so I ordered these blankets in a rush. The quality of the blankets seems good. They are very soft and cozy. Lightweight, yet warm. The only issue is that two blankets that should be identical in all ways other than color are actually not even close in size. No matter how hard I try, I cannot get these blankets to line up equally. I really don't like having one blanket hanging lower than the other, especially now that this bed is just inside our front door where every visitor can see it. The king size quilt should in theory cover this discrepancy, but it doesn't fit correctly (another issue). It also means that the blankets are not equally distributed over me and my husband at night. Other than the size inconsistency, I really like these blankets and think they are good value, plenty warm for Wisconsin winters when doubled up with sheets and quilt.

Soft fuzzy polyester king sized fleece blanket with no static electricity
Size: King (90x102 Inch), Color: Grey, Size: King (90x102 Inch), Color: Grey
I ordered the gray color because it was cheaper than the other colors, but it looks nice. This blanket was actually a lot nicer than I was expecting. It is pretty thick, very soft, fuzzy on both sides, fits the king sized bed, and keeps me warm with little extra weight. It is breathable and doesn't make me sweaty. The price was really very good, better than what I saw when shopping in local big stores. This feels great on the skin, and is much more comfortable than heavy wool blankets or quilts. When folded up it doesn't take up much room. It fits well in the washing machine. One of the best features is that it doesn't seem to generate static electricity even in dry air. In general I don't care for synthetic fibers, but I'm making an exception with this blanket, which stays clean and fluffy after extended use. I've had it 2.5 months with no problems and no manufacturing defects detected. The hem stitching is tidy and strong, very neat. I'm thinking of ordering a smaller one to keep in the car for emergencies and outings. I wish all the colors were a similar low price. I have recommended this blanket to friends.

Best blankets ever
Size: King (90x102 Inch), Color: Navy
Gorgeous blanket. I have many of them. They wash up great and look good. They are soft and warm. I only returned this one because the color was off. It looked more like a light to medium blue, but is actually a very light blue.

Super soft, cozy and lightweight blanket
Size: King (90x102 Inch), Color: White
I absolutely love my blanket. It’s super soft and very comfortable, and it looks really beautiful. It keeps you warm, but it’s not very thick it’s on the lighter side. Even so, I highly recommend it
