The modern recovery problem
Your body never gets to fully release.
Cold offices, screen-lit evenings, workouts with no wind-down — most of us haven't had a genuine, dripping, whole-body sweat in months. That's what a sauna is for. Ember is the sauna that fits in a drawer.
One blanket · Six shifts
Designed to wring the day out of you
01
Deep Sweat
A dripping, sauna-grade sweat from your own bed — no studio, no membership.
02
Melt Tension
Deep heat loosens tight backs and heavy legs while cortisol winds down.
03
Sleep Primer
A pre-bed heat session drops you into the natural cool-down that triggers sleep.
04
Skin Glow
Sweat flushes and circulation leave skin flushed, clear and glowing.
05
Calorie Burn
Passive heating makes your heart work like a brisk walk — while you lie still.
06
Recovery Mode
Post-training heat increases blood flow to muscles that need repairing.
How it works
Thirty minutes. Four steps.
STEP 01
Roll it out
On the bed or sofa. Plug in, set 35–85°C and your timer.
STEP 02
Zip in
Sleeve Edition for reading & scrolling · Zip Edition for max heat.
STEP 03
Sweat
Far-infrared heats your core directly — the deep sweat builds by minute ten.
STEP 04
Shower & sleep
Rinse off, cool down, and ride the post-sauna calm into bed.

"The sweat is UNREAL. Towel-soaked, sauna-level, thirty minutes flat. I cancelled my $80/month studio membership the same week."

"Sleeve edition was the right call — I read my book while I melt. The sleep afterwards is the deepest I get all week."

Good to know
Questions, answered
How hot does Ember actually get?
Up to 85°C (185°F) at the highest setting — hotter than most $700 spa-brand blankets. Most people find their sweet spot between 60–75°C. The digital controller adjusts in single-degree steps with a 5–60 minute timer.
What's the difference between Sleeve and Zip?
The Sleeve Edition has arm openings so you can read, scroll or work while you sweat. The Zip Edition is a full cocoon for maximum heat retention. Heat performance is identical.
What does Dual-Zone add?
The Dual-Zone controller runs independent temperatures for your upper and lower body — warmer legs, cooler chest, or the reverse. It's the headline feature of the $699 blankets, built in for $20.
What do I wear inside it?
Light cotton layers — long sleeves, socks and joggers. This protects your skin and soaks the sweat. The waterproof PU inner wipes clean in seconds after each session.
Is it safe?
Ember has automatic shut-off, overheat protection and a waterproof inner layer. Don't use it if you are pregnant, have a heart condition, or use an implanted electronic device — consult your doctor first. Stay hydrated before and after sessions.
What if it's not for me?
Sweat in it for up to 60 nights. If you don't love it, send it back for a full refund — no restocking fees. Every blanket carries a 2-year warranty.
