Therasage Flex Portable Lie-Down Infrared Sauna

Portable Lie-Down Far-Infrared Sauna for Full-Body Home Wellness

The Relax Saunas Flex Lie Down Sauna brings far-infrared heat into a portable, lie-down format designed for a full-body sauna experience at home. A reflective interior mat and mat cover distribute far-infrared warmth throughout the tent, and an inflatable headrest with manual air pump adds comfort during a session.

The Flex uses the same patented dual far-infrared conductor system found across the Relax sauna line, providing the same core heating technology as Relax's seated models in a lie-down format.

For individuals who prefer to stretch out fully during a sauna session, or who want a portable option that sets up and packs away easily, the Flex offers a practical, accessible solution.

Who This Sauna Is For

The Flex is well suited for individuals who want to lie down fully during a far-infrared sauna session, rather than sit upright. Its portable, retractable design makes it especially useful for homes, apartments, bedrooms, home gyms, or other spaces where a permanent sauna installation may not be practical.

Why Choose the Flex Lie Down Sauna?

Far-Infrared Heat Technology

The Flex operates within a far-infrared wavelength range of approximately 7 to 14 microns, or 7,000 to 14,000 nanometers. Far-infrared saunas use radiant heat rather than relying solely on extremely high surrounding air temperatures, creating a warm sauna environment in a compact enclosure.

Many people incorporate infrared sauna sessions into their wellness routines for relaxation, post-exercise recovery, warming muscles, and creating a calming environment after physical activity or a demanding day.
