As the title says, has anyone bought a down alternative/synthetic down comforter that is not garbage after a year?

Back in August I bought the Pottery Barn Hydrocool down alternative duvet insert.

I am currently a college student and thus funds are limited, however I am a chronic insomniac and have a lot of sleep issues, so a good comforter was something I was willing to splurge on. It was definitely not the most expensive option on the market, but for $150, I didn’t expect it to completely fall apart within 9 months. By the time I moved out of my dorm in May, the filling had bunched up into pockets, leaving parts of the comforter completely flat.

I’m now going back to school for my sophomore year and would like to buy a comforter/duvet insert that will last until I graduate. I have a down comforter at home and it’s my favorite thing, but it requires too much upkeep for college. Wirecutter, The Strategist, etc. all love the Brooklinen, Buffy, Parachute, Company Store, LL Bean, etc. but I keep seeing reviews on the stores’ sites themselves and on reddit that they all have this issue.

So, if anyone has bought an down alternative comforter in the past three years—from one of the brands listed above or anywhere else—that is still relatively intact, tell me!!

My title probably covered it all. No matter how low I turn my AC, I wake up sweating. My current comforter and duvet aren't great and I think both have polyester.

I'm an animal lover and can't support down or feather but I really miss the super plush company store down comforters my best friend had when we were kids. Basically I'd like it as plush as possible but not hot.

Does anyone have something like this that they can recommend?
