Why I started this

A hot water bottle that went cold at 2am, and a category that nobody had bothered to design for grown-ups.

This starts with a hot water bottle going cold at two in the morning, which is not a dramatic origin story, but it is the true one.

I'd been reaching for it most nights for about a year. Not for anything medical — just for the end of the day, the half hour where you're too tired to do anything useful and not tired enough to sleep. It worked, for about twenty minutes, and then it became a lukewarm thing in the bed that I had to get up and deal with.

So I went looking for the version of it that someone had presumably already made. A heated, weighted object designed for an adult, that stayed warm, that I could wash.

What I found instead

An entire category, and all of it aimed somewhere else.

Microwavable plush, in the gift aisle, weighing nothing, impossible to wash, and smelling of warm cereal after the first year. Weighted blankets, which work, and which are hot in the wrong way and a nuisance to wash. Electric heating pads, which are excellent and look like medical equipment and tether you to a wall.

And then a growing shelf of cheap heated stuffed animals: no published temperature, mostly no automatic shut-off, and — when I eventually got some numbers — running at around 57 °C. Which, when you look at the actual time-and-temperature data on skin, is not a number anyone should be sleeping on.

Every one of them was designed for a child and then listed for an adult without changing anything except the photographs.

The thing I actually want

Heavy enough to stay where I put it. Made of a fabric I want to touch. Warm without a cable, a charging habit, or a bag of wheat quietly going off inside it. And — this is the part that sounds shallow and isn't — good-looking enough that I don't put it in a drawer when someone comes over.

That last one is most of the product. There is a version of this object that is embarrassing to own and a version that isn't, and the difference is entirely design.

What this newsletter is

Twice a week, whatever actually happened. Samples that came back wrong. Prices that turned out to be worse than I'd planned. The decisions I'm not sure about.

I'm writing it partly because I want the people who eventually buy this to know how it was made, and partly for a more self-interested reason: it is much harder to quietly lower your standards when you've told several hundred people what they were.
