Soft, Cozy, and Great Quality
Color: White/All Season, Size: King
This comforter is very soft and comfortable. It feels light but still keeps me warm, perfect for all seasons. The cotton cover feels nice and breathable, and I like that it’s hypoallergenic. It gives a hotel-like feel to my bed.

High quality, but it makes a sound like crinkling.
Color: White/All Season, Size: Queen
I enjoy the warmth of this comforter. Yet very lightweight. It is not as big and fluffed up as the first photo. It does feel like hotel softness and has loops for a duvet cover. The only thing I don't like is the sound it makes. It crinkles when you move it around. If it made no sound I would rate 5 stars.

Hotel-like comfort at home
Color: White/All Season, Size: King
This Serta duvet has surprised me very positively. Since I took it out of the packaging it feels of good quality, with a soft and pleasant to the touch cotton fabric. The King size (106 x 90 inches) perfectly covers the bed and falls very well on the sides, which gives it an elegant look.
I like that it is of medium warmth, because it works well throughout the year without feeling too heavy or too light.
Another point in favor is that it is hypoallergenic, something important if you are sensitive to dust or certain materials. So far it has maintained its shape well and has not been lagged.
In general, it is a very good option if you are looking for a comfortable duvet, with the appearance of a hotel and that you can use in any season.
