Nice like Down and thick.
Size: King/Cal King Style: Extra Warmth
We love this comforter. It fluffed up just fine in a few hours. It is warm ab and soft. We went from Down comforters. I was tired on the feathers shifting and ending up at the bottom of the bed. This stays put and is warm top to bottom. My husband and I just love going to bed because of this comforter It was worth the cost. ... show more

Extra warmth comforter
Size: Full/Queen Style: Extra Warmth
I purchased the extra warmth comforter, and it doesn't dissapoint! I went from 4 different blankets on my bed to this one (added a comforter cover I purchased seperately) and stayed toasty on a -20F night. It's very lightweight, so if having that kind of weight on you is your thing, stick with the 4+ blankets. This comforter is awesome for cold weather, and I would definitely say worth the money. ... show more

superb
Size: Full/Queen Style: Extra Warmth
amazing!! i genuinely did so much research about duvets in order to find the best one, starting from basically no knowledge about duvets at all, and i’m so glad i landed on this. i think the biggest selling point for me was that serta is an actual, well known brand that sells bedding/mattresses in home stores so it kinda made me less suspicious lol. i opted for the extra warmth and it’s so heavy and fluffy, exactly what i was looking for 😁 also, no fallout like down comforters since it’s synthetic which i knew i would be annoyed about if i had opted for the latter. worth it!! ... show more

THIS IS THE ONE YOU WANT TO BUY
Size: King/Cal King Style: Extra Warmth
The first pic is after it was fluffed in the dryer and by hand. The second is straight out of the package. I have read ALL the reviews for EVERY down alternative comforter there is. Well, maybe not EVERY one but it sure feels like it! I’ve done my research. I’ve bought and returned. I got the extra warmth. This one is the one you need. It’s soft, decently thick, quality materials and workmanship. Do I want it thicker? Yes! But I’m looking to sleep in a cloud. I’m “extra” with everything. This is as good as it gets. And the price! So affordable! So, in total I have purchased 4 of these in King, 110x96 but for Queen beds. 3 for kids/guest beds. And 1 for mine temporarily until I can find one big enough for my king, 130ish x 96-100ish). (I wish they made oversized but it seems like I will have to get something straight from China to get it big enough or custom made $$$!). So, when I do find one, I’ll take mine and put it in with another insert and if I love the thicker look, I’ll be buying 2 more. It really is a GREAT down alternative comforter. ... show more

Amazingly warm!
Size: King/Cal King Style: Extra Warmth
My new comforter arrived yesterday, and last night was the first really chilly fall night this year. I am extremely cold natured, and spend 6 months of the year sleeping in heavy pajamas and socks, with a light comforter, two to three quilts, and a doubled wool blanket on top of the lower half of the bed. This comforter arrived on time packaged nicely, and after running it through the dryer on "air" for 10 minutes, I put it on my bed with just a sheet. It's puffy, but very light, and I had serious doubts it would be warm enough. I even put a quilt within easy reach if it wasn't. WHAT A WONDERFUL SURPRISE!!! I was perfectly warm all night--no quilts required! It felt fabulous to not have all that weight pressing me into the mattress! This comforter is everything it says it is and more! I'm going to buy another one for my backup. It's beautifully made of quality fabric, and looks like it will be quite durable. My bed is a queen, but the mattress is thick and the bed is high, so I bought a king and turned it sideways. It's perfect! ... show more
