Who should skip
- Skip Atlas if the room is closet-sized — start Sierra.
- Skip Sierra if two adults need full recline daily.
- Skip Atlas One if red light is curiosity, not a daily habit.
- Skip SaunaCloud if you need heat this weekend, refuse a dedicated circuit, or want traditional rock steam only.
- Skip this niche if you came for CBD/supplements — we do not sell that.
