Community verdict

Feedback for Casper mattresses leans heavily critical, though long-time owners of older models occasionally report high satisfaction. Happy buyers highlight initial comfort and convenient boxed delivery, but negative accounts dominate recent experiences. The most common complaints center on severe premature sagging, uncomfortable firmness that causes back or shoulder pain, and persistent chemical off-gassing smells.

My casper is 5 years old and I'm in love with it. I find that it even helps my back when I throw it out.

I have a Casper that I bought back in 2014... and as a person who spends half the year sleeping in hotels and Airbnbs it's still my favorite mattress.
