For generations, climbers and mountain athletes have trained high up where the air is thinner. Summit Session brings that idea down to sea level: you sit comfortably and breathe through guided intervals of altitude-style air, then everyday air, without ever leaving the lounge.

Your specialist fits a soft mask, checks in on how you're feeling and starts with a gentle first interval. The air feels a little lighter, much like stepping off a ski lift high in the mountains. You stay seated and breathe naturally the whole time.

Throughout the session, the system alternates between lower-oxygen air and normal air in a steady rhythm, like a short trip up the mountain and back down, again and again. Your specialist watches each interval and adjusts the pace so it feels right for you that day.

Because it's seated and low-impact, Summit Session is designed to sit alongside your runs, rides and gym days rather than replace them. Many members book it on lighter days, or in the weeks before a trip to the mountains.

After a focused Summit Session, members often head to the Reset Chair to downshift, or round out their visit with the Lumen Bed. It's an easy way to turn one session into a full Playground ritual.

When the last interval ends, the mask comes off and you're ready to get on with your day, with no downtime needed. Members often tell us they walk out feeling focused and quietly accomplished, like they've just come back from somewhere high and clear.
