Color and weight are perfect
Team Name: Lightweight Comforter, Size: King, Color: Sage Green, Team Name: Lightweight Comforter, Size: King, Color: Sage Green
Perfect, lightweight; just what I was looking for. It’s soft and feels nice. Sage Green color is true to the photo. I bought a king for a queen bed, I’m glad I didn’t get the queen because it would have left my mattress visible but I can still see the bed with the king. For the price, it’s okay quality and I’m okay with that.

Lightweight, Cozy, and Affordable!
Team Name: Lightweight Comforter, Size: Queen, Color: Lavender Purple
This comforter is such a great value for the price. It’s lightweight but still warm and cozy, making it perfect for year-round use. The fabric feels soft to the touch, and it fluffs up nicely right out of the package. The queen size fits my bed perfectly and looks great once styled with pillows. It also washes well — I tossed it in the washer and dryer and it came out just as fluffy as before, no clumping or shifting. If you want a comfortable, budget-friendly comforter that looks and feels nice, this is definitely a great pick!

King Size does not include corner tabs
Team Name: Lightweight Comforter, Size: King, Color: White
DISCLAIMER - KING COMFORTER DOES NOT HAVE CORNER TABS I've ordered 2 comforters prior to in the Queen size which included handy corner tabs to secure the duvet cover. I recently ordered in the King size and the tabs weren't there. Thinking I got defective product, I returned and was sent a replacement. I was disappointed to discover the replacement also didn't have tabs, so I guess the comforters made in the King size just don't have them. It would be helpful to have that listed somewhere in the product details. It's not worth the trouble of returning again so I'm keeping it. Otherwise the lightweight feel of this comforter is great for Florida weather, obviously we liked these so much we have three in our home now!

Perfffff
Color: White, Size: Oversized King, Color: White, Size: Oversized King
So very comfy! I did not expect to love this as much as I do. I was worried about it being too hot. It’s not. I was used to sleeping with a quilt but this is so comforting, the weight of it is so cozy & perfect. I sized up with oversized king for my king size duvet cover. Its so fluffy and perfect for the aesthetic I wanted
