Run hot.
Sleep cold.
FYROST builds recovery technology around the oldest ritual in the world — deep heat to release, true cold to restore. Sauna-grade infrared, cellular PEMF and glacier-cool sleep, without the spa membership.
Heat releases.
Cold restores.
Sweat like a sauna
Ember wraps you in far-infrared heat up to 85°C while Aura pulses electromagnetic recovery through every cell. Thirty minutes. Full release.
Sleep like a glacier
Glacier circulates chilled water beneath your sheet all night — the cold side of the pillow, engineered for your whole body.
Sixty minutes to a different morning.
Burn · 30 min
Zip into Ember. Far-infrared heat takes you to a deep, dripping sweat — cortisol down, circulation up.
Recharge · 20 min
Lie back on Aura. Eight PEMF coils pulse gentle fields that settle the nervous system after the heat.
Freeze · all night
Glacier holds your bed degrees below room temperature. You fall asleep faster and stay asleep colder.

The spa-brand tax, removed.
Fire & frost.
Every night.
