Trickle-down comfort: a forty-year experiment in not sleeping
We gave all the fluff to the top pillow and waited for it to reach the rest of the bed. We are still waiting.
In the early days of Sleep Left, we ran a simple thought experiment. Stack twelve pillows on a bed and put all of the fill in the one at the very top. The theory, which has been popular in certain circles since roughly 1981, is that the top pillow becomes so plush, so prosperous, that the excess comfort naturally trickles down to the eleven below.
It does not. The top pillow gets fluffier. The top pillow buys a second, smaller pillow for its lake house. The eleven pillows underneath go flat, and several of them start working two shifts as couch cushions.
What actually works
So we tried something radical: put fill in every pillow. Adjustable fill, so each sleeper decides how much support they need. Comfort goes up across the whole bed, and the top pillow is fine. It still has plenty. It just doesn't have all of it.
That's the whole philosophy behind The Bottom-Up Topper and, frankly, behind this company. Build comfort at the base, and everything above it rests easier.
