OtterSpace

OtterSpace makes portable blackout curtains for people who cannot permanently darken a room: parents of light-sensitive sleepers, renters, night-shift workers, and travelers. The kits mount without tools or drilling, and a magnetic seal runs the full window perimeter so the curtain closes the edge light that ordinary panels leave behind while still pulling away in seconds when daylight is wanted.

Where suction-cup and adhesive travel blinds such as Sleepout and Tommee Tippee's Sleeptime blind seal only where their mounts land, OtterSpace's full-perimeter magnetic closure is the mechanism that separates it, and it fits any window without a rod or a fixed frame; against rod-hung panels such as NICETOWN's it trades the lowest price for damage-free installation and portability. Its position rests on that mechanism and on a science-led origin rather than price or breadth in a niche shaped by travel and rental use.
