My mattress is eight years old. Apparently that's about the time mattresses turn from comfortable havens to spike-filled death rectangles. So instead of going to a giant mattress showroom and trying out mattress after mattress, I caved and bought a king sized Casper.1

My grandparents would shake their heads if I told them I bought a mattress without ever trying it out. But with the 100 day trial, I don't really see much of a risk other than time.

I'm going to make short notes on how I feel every morning, so I can decide if this is the right mattress. I'll be updating this post every time I make my notes. You can also follow on Twitter, with the hashtag #casper100.


Day 001 The Casper arrived while I was at work. My wife and son got to unbox it, which is apparently some sort of event.

It feels comfortable to lay on. Very different from my old mattress, though. You sink in a bit - like memory foam - but them you stop. You don't melt into the mattress like it was quicksand.
