Our technology design mitigates EMFs to a lower level than most common household items. The air is not suffocating or harsh, it’s a gentle, comforting warmth. The Signature III seats up to three people, with a comfortable, multi-function bench that can be removed to maximize room for stretching or simple yoga poses. Our powerful Magne-seal locking method makes assembly easy and keeps heat in with no unsightly screws or nails. Chromotherapy lighting enhances your home sauna experience using colors from the sun’s visible light spectrum to bring balance and mental wellbeing.
