Casper One Mattress
Community verdict
The Casper One and related all-foam Casper models divide buyers between those who appreciate its straightforward foam support and those dissatisfied with its feel over time. Satisfied owners highlight the convenient box delivery, low motion transfer, and comfortable cushioning for the first few years. However, critical reviews consistently point to severe off-gassing smells upon unboxing, unexpected surface firmness causing back or shoulder pain, and sagging after extended use.

Simple, comfortable, and one of those beds people lay on and instantly go “yeah… this is the one.”
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.
Pretty standard firmer memory foam mattress, but if you want \"firm\" then don't look for foam products to be honest.
Do not ignore reviews about Casper mattress off-gassing... deeply regret my purchase.
