SERTA ComfortSure Soft Box Stitc... vs LINENSPA All-Season Reversible D...

The extra length for the twin xl allows me to tuck the comforter in. I didn't have any issues with the filling bunching or shifting.

It's very flat and not comparable really to other down alternative duvet inserts. In my honest opinion, it's just ok.

It’s long enough on the sides than when my husband steals the covers i still have some to cover me. Once it fluffs up it looks great. Will be placing a cover on it soon.

The fabric is soft (perhaps too soft). It feels like nylon and it looks more like mattress cover material, only thinner. The only time i would recommend this is if you're sleeping outside.
