Total-body rejuvenation.

The Relax Flex Lie Down Sauna offers the complete far infrared experience in a horizontal format, perfect for deep rest, advanced detox, and systemic recovery. Using the same patented semiconductor system found in our Black Pro and Silver Elite models, it delivers 100% pure far infrared light (7–14 microns) directly to the body’s core, activating mitochondria, increasing nitric oxide, and penetrating up to 2–3 inches into tissues for real biological change.

With 1400W of medical-grade FIR output, far infrared intensity exceeding 40 mW/cm², and low-EMF operation, this fully portable system surrounds you in therapeutic light while you recline. Ideal for clients with mobility limitations, chronic fatigue, or those seeking a deeper parasympathetic reset, the Flex model creates a cocoon of healing. Its reflective mat amplifies heat, circulation, and detox, clearing heavy metals, plastics, and inflammatory waste through sweat, breath, and lymph.

Set it up in minutes. Relax in clothes or under a towel. When you're done, it rolls up and stores easily, no installation or tools required.

Includes folding FIR tent with zippered top, padded mat, dual radiators, air pump, controller, and carry bag. Weight: 18 lbs. Dimensions: Tent 65” x 26” x 19”; Mat 78” x 36”.
