How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
What is a Manta sleep mask?
The Manta sleep mask is hailed as one of the best sleep masks around.
It is a revolutionary sleep accessory designed to provide you with the ultimate comfort and enhanced sleep environment for deeper sleep so you can wake up feeling refreshed more regularly. 😴
But unlike traditional sleep masks, the Manta sleep mask features a soft, velvety strap with two soft and spongy eye cups that can be removed from the strap, placed closer together or further apart, or even replaced with one of the Manta sleep accessories.
This definitely makes the Manta blackout eye mask one of the most unique sleep masks we’ve ever come across.
Let’s look at the key features of the Manta sleep mask in a bit more detail.
Breathable and soft materials for comfort
The Manta sleep mask is crafted using breathable and soft materials, ensuring comfort throughout the night.
It is even advertised as “the world’s comfiest 100% blackout sleep mask” for higher-quality sleep.
While the eye cups are made of Modal fabric, the head strap is made of a breathable polycotton.
Both materials are super soft - the strap has a velvety feel for snag-free comfort, while the cups themselves are quite spongy. 🤗
The softness of the materials ensures that the eye mask is comfortable to wear, while the breathability ensures good airflow and sweat absorbency, which prevents overheating.
The Sleep Hero team tested the Manta sleep mask during a London heat wave - and we can confidently say that the sleep mask never felt hot or clammy on our skin.
Contoured design to prevent pressure on the eyes
Unlike traditional sleep masks that lie flat on the skin, the Manta eye cups are indeed that - cups.
This leaves ample space for your eyes and eyelashes, creating a zero eye pressure environment.
That said, sleepers with longer eyelashes may still feel some grazing, as one of our testers did.
But Manta sells separate eye cups (more on this further down) designed for bigger eyes and fuller lashes that you can add to your purchase.
The padded, contoured design as a whole is fabulous for the no-pressure feel, but it does mean the eye mask is slightly more bulky.
This won’t affect you if you’re a back sleeper.
But side sleepers may find that, depending on their build and position, the padding is pushed up from the pillow, creating a small gap that hinders the full blackout experience and may feel a tad uncomfortable. ☀️
The ladies reading this can best liken it to wearing a padded bra while sleeping.
Since the Manta sleep eye cups are quite soft, though, and have a tapered design, we didn’t feel this push-back as much as we did with other padded sleep masks, so we would still recommend it to side sleepers.
This is just something worth being aware of.
Maximum light blocking for an enhanced sleep environment
The unique design of the Manta sleep mask blocks out 100% of light.
Even in broad daylight, our testers could experience a full blackout experience during our Manta sleep mask review.
This is great news if you’re looking to nap during the day, need a quick snooze at the office or while travelling, or even if you’re looking to sleep more comfortably during the UK’s shorter summer nights.
The full blackout experience is due to the ergonomic design of the mask and the eye cups.
But since you can change the positioning of the eyecups, you may get a slightly different experience depending on how you’ve positioned the cups. 🔧
For example, when our testers first tried the mask straight after unpacking, it offered the full blackout experience.
But moving the eye cups slightly further apart to create more space around the nose (those with sinus problems may experience some pressure here) resulted in some light coming in.
If you don’t get the full blackout experience upon first trying the mask, you may need to move the cups around a bit so that they fit perfectly to block out all light.
This brings us to the last, and probably the most unique, feature of the Manta sleep mask we’d like to explore.
Adjustable fit for a personalised experience
Most sleep masks are adjustable to some extent since you’d need to adjust the strap to fit around your head.
The head strap itself is 73 cm (28.7 inches) in circumference but can be positioned more tightly or more loosely, depending on the size of your head (or hair-do).
We found a slightly looser fit (though still ensuring the mask stays on without slipping off) the most comfortable during our Manta sleep mask review, but your experience may be different.
But what does make the Manta mask so very unique is that the eye cups are removable.
This may seem a little overwhelming at first.
What if you don’t get the perfect fit?
What if you mess up the design?
We had those thoughts, too - as did the designers at Manta - since they very obviously thought of this.
Here are a few fundamentals when it comes to adjusting the eye cups:
- The velcro-type part on the back of the eye cups is only positioned in the centre of the eye cups, and it only sticks to the middle part of the mask, meaning that whichever way you’ll stick it on, you’ll have the soft, squishy foams resting comfortably on your face.
- The eye cups are tapered (they look a bit like an egg), so you’ll know that the fattest part of the cup should be positioned towards your nose, while the thinner part should be positioned towards your ears. This ensures a more comfortable sleep.
- But in case you miss the tapering, Manta has also placed little “your nose >” labels on the inside of the cup to show exactly which way to place the cups onto the mask.
- Despite the velcro pad and the label, the cups are so soft that our testers never felt either of these features while wearing the mask.
While you may never get the eye cups back to their original positions once you remove them (unless you take a photo to better remember where they were), you will be able to move them to exactly where you need them. 📸
Have a bigger nose or wide-set eyes? Simply move the eye cups further apart.
Have a small head or very close-set eyes? Move the eye cups closer together.
Have eyes that are positioned slightly differently or have had a broken nose that’s a little crooked now?
That’s okay, too; Manta has got you covered - simply position the eye cups further up or further down, depending on your requirements.
We’ve even been adjusting the eye cups depending on other factors.
For example, we’ve found a slightly looser fit around the nose feels more comfortable with sinus problems, hay fever attacks, or headaches, so, in these instances, moving the eye cups further apart is better.
But if we’ve been looking for a complete blackout experience to meditate for ten minutes during our lunch break, then the tighter fit and moving the eye cups more closely to the nose works better.
The customisation options are endless.
Who is the Manta sleep mask suitable for?
There’s really no limit to who would find the Manta sleep mask suitable, but there are a few categories of people who may be more inclined to purchase this product.
Those looking for improved sleep quality and duration
Getting good sleep with light pollution can be difficult.
Perhaps you live in a very busy part of the city, you don’t have black-out curtains to block out the sun late at night or the sunrise early in the morning, or you’re just particularly sensitive to light.
Or, perhaps, you’re simply looking for a better way to nap at home or at the office.
Either way, the Manta sleep mask offers a 100% blackout experience while still being soft and comfortable for all types of sleepers.
This means you can finally shut out the outside world and snooze away.
People after enhanced relaxation and stress relief
The steam eye cup and cool eye cup add-ons are particularly useful for those looking for enhanced relaxation and stress relief.
These additional eye cups are easy to use (either 30 minutes in the freezer or 20 seconds in the microwave) and provide all the relief you need for tired, stressed, or dry eyes.
You can use these eye cups for quick recovery after a long day or work them into a longer beauty routine for all-round wellness.
The original eye mask is also great for people wanting to shut out the outside world while meditating during the day.
Frequent travellers or shift workers
Frequent travellers or shift workers are often exposed to less-than-ideal sleeping conditions.
Regardless of whether this involves trying to sleep while on a plane or train, dealing with jet lag, or having to sleep during the brightest hours of the day, the Manta sleep mask can provide a blackout experience no matter where you are. 🚗
It’s also soft, light, and comes with a travel pouch, so you can easily take it with you wherever you go.
What does the Manta sleep mask UK cost?
The Manta sleep mask may be more expensive than standard eye masks for sleeping you’ll get on Amazon, but it is of significantly higher quality.

The mask is also made of durable materials, so you’ll likely use it for a long time coming.
Of course, you’ll pay extra for the Manta sleep accessories.
