About Us — Manta Lseep

Made by light sleepers, for light sleepers.

mantalseep exists for one reason: to empower light sleepers to sleep better, so they can live their best lives.
We believe great sleep is the non-negotiable foundation of a great life. That it’s impossible to unlock your full potential if you’re running on empty. And that an afternoon nap beats a third cup of coffee, hands down. Everything we create is driven by a simple goal — enabling better lives through better sleep.

The Problem

The modern world doesn’t exactly make it easy to rest. Endless screens, city noise, and light pollution chip away at your sleep — and hustle culture tells you to just “grind harder.” After decades of being told that rest is a luxury, millions of us are searching for better ways to truly recharge.
We know the feeling better than anyone. Because mantalseep was started by light sleepers — for light sleepers.

Where It All Began

Our founders spent years in the corporate world, living through the same grind and hustle culture that looks down on proper rest. For more than 15 years, they slept with flimsy, light-leaking, sweaty sleep masks that never quite worked. Until one morning, they hit their breaking point.
As the saying goes: if you want something done well, do it yourself. So they did.
After 11 design iterations, 25 manufacturing partners, and 30 fabric evaluations, the first mantalseep Mask was born — built on thoughtful, science-backed design. A very successful Kickstarter campaign and thousands of happy early customers later, Manta Sleep was officially launched.

What We Make

Our goal has never been to make “just another sleep mask.” It’s to build the most advanced, best-performing sleep products in the world — meticulously engineered for deeper, more restful sleep:
  • 100% blackout — true total darkness in any environment, from your bedroom to a plane to a campsite.
  • Infinitely adjustable eye cups — a tailored, personalized fit for every face.
  • Modular, breathable design — crafted for comfort you can wear all night.
  • Earplugs engineered for side sleepers — because comfort shouldn’t stop at your eyes.
  • Premium materials that are built to last.

Where We Are Now

A decade in, the results speak for themselves. Our SOUND Mask was named one of TIME’s Best Inventions of 2025, and our PRO Mask has been proven to boost deep sleep in athletes.
Today, more than 2 million light sleepers trust mantalseep to help them rest better. But the numbers are only part of the picture. What matters most to us is the real stories — people finally getting the rest they deserve, and proving that better sleep really does transform lives.

Our Promise

We stand behind everything we make:
  • 60-Day Money-Back Guarantee — take your time, sleep on it (literally), and if you’re not completely satisfied, we’ll make it right.
