Seven levels, not three
Barely-there at the desk, high on the couch. Most people settle in the middle of the range for everyday use and turn it up when the room is really cold.
Heated · Hooded · Wearable
A hooded, sherpa-lined blanket you wear. Seven heat levels, plugs into any outlet, shuts itself off after four hours.
Your house is cold and turning up the heat means paying to warm every empty room in it. The Amberly warms the one place that matters — the chair you're actually sitting in.
It's a flannel blanket with sleeves and a hood, lined in sherpa, with a heating element running through it. Seven levels, so you can run it barely-there at your desk or turn it up on the couch. It plugs into a standard outlet rather than a battery, which means the heat stays steady for as long as you're sitting there instead of fading out after two hours.
After four hours it shuts itself off. You don't have to remember it.
Made for sitting still — working from home, reading, watching something. Cord included; you'll want an outlet within reach.
Unplug it, detach the controller, and the whole thing goes in the washing machine. Cold cycle, tumble dry low.

Why it works
Turning the thermostat up pays to warm every empty room you're not sitting in. The Emberly warms the one place that matters: the chair you're actually in.
220 W at $0.17/kWh, roughly the U.S. residential average. Your rate may differ.
Every room, all evening — including the ones nobody is sitting in.
One chair, one person, 220 W — about what a few light bulbs draw.
What it does
Working from home, reading, watching something. Everything about it is built for the hours you spend in one chair.
Dial it in
Barely-there at the desk, high on the couch. Most people settle in the middle of the range for everyday use and turn it up when the room is really cold.
Constant heat
Battery-powered wearables run down and need recharging. The Emberly runs off a standard outlet, so the warmth stays exactly where you set it for as long as you're sitting there.
Cord included — you'll want an outlet within reach.
Safe
Fall asleep in it. After four hours it switches off on its own, so nothing is left running. Switch it back on to keep going.
Washable
Unplug it, detach the controller, and the whole thing goes in the machine. Cold cycle, tumble dry low, and make sure it's completely dry before plugging back in.
Flannel on the outside, sherpa on the inside, and a hood for when your head is cold too.
Roomy enough to pull over whatever you're already wearing.
How it works
Pull it over whatever you're already wearing. Hood up if your head is cold too.
Any standard outlet near where you sit. Run the cord behind the chair or along the couch.
Seven settings. Start in the middle and adjust from there.
It shuts off on its own after four hours, so nothing is left running.

Typical characteristics of each category; specific products vary.
There are seven heat levels. Level one takes the chill off at a desk; the top levels are for a genuinely cold room. Most people settle somewhere in the middle for everyday use.
Yes. It shuts off automatically after four hours. To keep going, switch it back on.
No — it plugs into a standard 120V US outlet. That's the point: the heat stays constant for as long as you're sitting with it, with nothing to recharge. The cord is included, so you'll want an outlet within reach of your chair.
Yes. Unplug it and detach the controller, then machine wash cold and tumble dry low. Make sure it is completely dry before plugging it back in.
Flannel on the outside, sherpa on the inside, with a hood and sleeves. The heating element runs through the body of the blanket.
One size, designed to fit most adults, and roomy enough to wear over whatever you already have on.
It draws 220 watts, which works out to roughly 4¢ an hour at typical US electricity rates — a fraction of what it costs to heat a whole room.
