Do cheap comforters hold up over time?

It's the most honest caveat in the data. Budget inserts earn strong value praise, but community reviewers warn that some pressed-down comforters 'go completely flat' after about three years and that fill can migrate to the edges. Down alternative tends to be easy to refresh in the dryer, while cheaper natural-fill inserts can clump; using a duvet cover and periodic fluffing extends life either way.
