Best Sleep Masks for Side Sleepers in 2026

Side sleeping is the most common sleep position, with research from the National Sleep Foundation showing that approximately 74 percent of adults prefer to sleep on their side. Yet most sleep masks are designed and tested with back sleepers in mind, which means side sleepers often struggle with masks that shift, bunch, create pressure points, or leak light around the edges when their face presses into the pillow. In this guide, we identify the specific challenges side sleepers face, explain what design features to look for, and recommend the best sleep masks for side sleeping in 2026.

Why Side Sleepers Need Different Sleep Masks

When you sleep on your side, several forces work against a standard sleep mask. First, the pillow pushes against one side of the mask, which can cause it to shift upward or downward, creating gaps where light leaks in. Second, the strap that holds the mask in place must resist lateral forces rather than just the pull of gravity, which means it needs to be more secure without being uncomfortably tight. Third, the mask material bunches and folds against the pillow, which can create pressure points on the eye socket and temple. A well-designed side-sleeper mask addresses all three of these issues through low-profile construction, adjustable straps, and contoured eye cups that maintain their shape under lateral pressure.

Contoured vs. Flat Masks for Side Sleepers

Flat masks are the traditional design: a piece of fabric or padded material that lies directly against your face. They are lightweight and pack easily for travel, but they tend to press against your eyelids when pillow pressure pushes them inward. This is uncomfortable and can actually disrupt REM sleep by interfering with rapid eye movements. Contoured masks use molded cups or raised structures that create space between the mask and your eyes. This design is superior for side sleepers because the cups maintain their shape even when compressed against a pillow. The Manta Sleep Mask and Manta Sleep Mask PRO are the standout contoured options, featuring independently adjustable eye cups that you can position for a perfect fit regardless of your face shape.

Best Overall for Side Sleepers: Manta Sleep Mask PRO

The Manta Sleep Mask PRO earns our top recommendation for side sleepers with its deep, contoured eye cups and micro-hook head strap. The eye cups are deeper than the original Manta, providing generous room for your eyes even when the mask is pressed against a pillow. Each cup attaches to the mask body with a hook-and-loop system, so you can adjust their position in any direction to find the perfect seal against light. The head strap uses a micro-hook closure rather than a buckle or slide, which means you can make millimeter-level adjustments to get a secure fit without overtightening. At $49, it is pricier than basic masks but delivers a meaningfully better experience for side sleepers.

Best Budget Option: Mavogel Cotton Sleep Mask

The Mavogel Cotton Sleep Mask solves one of the biggest problems for side sleepers at a price under $10. Its patented nose baffle uses a flexible cartilage strip that bends along your nose bridge, eliminating the light leakage that plagues most flat masks. The breathable cotton construction keeps the mask comfortable even when pressed against a pillow for hours. The elastic headband distributes pressure evenly and stays in place through position changes during the night. With over 45,000 reviews and a 4.3-star average, it has proven its reliability across a huge range of face shapes and head sizes. The main trade-off is that as a flat mask, it does put some pressure on your eyelids, which may bother light sleepers during REM phases.

Best Silk Option: Lunya Washable Silk Sleep Mask

Silk masks are popular for their skin benefits and luxurious feel, but most silk masks shift easily on side sleepers because the slippery material does not grip the face. The Lunya Washable Silk Sleep Mask addresses this with a padded nose bridge that contours to your face and internal padding that adds just enough structure to prevent shifting. The adjustable elastic strap secures the mask without pulling your hair or creating pressure points. Unlike many silk masks, the Lunya is machine washable, which is a significant practical advantage since side sleepers press their masks against pillow surfaces that accumulate oils and dead skin. At $48, it competes with the Manta PRO on price but offers the skin-care benefits of mulberry silk.

Best Value Silk: Alaska Bear Silk Sleep Mask

The Alaska Bear Silk Sleep Mask is a remarkable value at under $10. Made from natural mulberry silk, it is exceptionally lightweight and gentle on delicate eye-area skin. For side sleepers, its thin profile is actually an advantage: there is less material to bunch up when your face presses into the pillow. The adjustable elastic strap keeps it in place reasonably well, though it is not as secure as the Manta PRO's micro-hook system. The main drawback for side sleepers is light leakage around the nose bridge, which is a common issue with flat silk masks. If you can tolerate a small amount of light seepage, the Alaska Bear offers a luxury sleep experience at a fraction of the price of premium competitors.

Best for Total Blackout: Manta Sleep Mask (Original)

The original Manta Sleep Mask remains an excellent choice for side sleepers who prioritize complete light blockage above all else. Its adjustable eye cups create deep wells of total darkness that maintain their seal even during side sleeping. The cups are slightly less deep than the PRO version but still provide ample room for eye movement. The head strap is wider than most competitors, distributing pressure over a larger area for better comfort during long side-sleeping sessions. At $35, it offers most of the PRO's benefits at a lower price point. If you do not need the extra cup depth and micro-hook adjustment of the PRO, the original is the better value.

Material Comparison for Side Sleepers

Material choice affects comfort, durability, and skin health for side sleepers. Silk masks like the Alaska Bear and Lunya minimize friction against the skin, which can reduce sleep creases and is gentler on sensitive eye-area skin. However, silk is less structured and more prone to shifting. Cotton masks like the Mavogel are breathable and easy to wash but lack the skin-smoothing properties of silk. Memory foam masks like the Tempur-Pedic Sleep Mask conform to your face shape for a personalized fit but can feel warm during hot weather, a particular concern for side sleepers since one side of the face is already insulated by the pillow. The Manta masks use a soft, breathable micro-fiber material with foam eye cups that balances comfort, structure, and breathability effectively.

Features Side Sleepers Should Prioritize

Based on our testing and analysis, these are the five most important features for side sleepers in order of priority. First, strap security: the mask must stay in place through position changes. Look for adjustable velcro or micro-hook closures rather than loose elastic. Second, low-profile design: bulky masks create uncomfortable pressure points when pressed against a pillow. Third, contoured eye cups: these prevent eyelid pressure and maintain their shape under lateral force. Fourth, nose bridge seal: the area around the nose is where most light leaks occur, especially for side sleepers. Look for adjustable nose baffles or padded bridges. Fifth, washability: side sleepers press their masks against pillow surfaces more aggressively, so the mask accumulates oils faster and needs more frequent cleaning.

How to Break In a New Sleep Mask

Even the best sleep mask may feel awkward for the first few nights. Give yourself a one-week adjustment period before deciding whether a mask works for you. During this period, wear the mask while reading or relaxing before bed to let your face adapt to the sensation. Adjust the strap so it is snug but not tight; you should be able to slide one finger between the strap and your head. For contoured masks like the Manta, spend time positioning the eye cups while sitting upright, then lie on your side and make final adjustments while in your actual sleep position. The goal is a seal that blocks light without creating any pressure points. If light leaks around the nose, try angling the mask slightly downward.

Combining a Sleep Mask with Other Sleep Products

For the ultimate side-sleeping setup, pair your mask with complementary products. A supportive side-sleeper pillow like the Coop Home Goods Original Pillow with adjustable fill lets you set the loft height that keeps your spine aligned, which also affects how your mask sits against your face. A weighted blanket like the Luna Weighted Blanket adds deep pressure therapy without interfering with your mask. If you use a noise machine, placement near your head can compensate for the slight sound muffling that occurs when one ear is pressed into the pillow. The LectroFan Evo placed on your nightstand delivers direct sound that reaches both ears effectively in a side-sleeping position.

The Bottom Line

Side sleepers do not need to settle for masks designed for back sleepers. The Manta Sleep Mask PRO is our top recommendation for its combination of deep contoured cups, micro-hook adjustment, and proven side-sleeper performance. Budget shoppers should try the Mavogel Cotton Sleep Mask for its nose baffle design and sub-ten-dollar price. Silk lovers will appreciate the Lunya Washable Silk Sleep Mask for its skin benefits and machine washability, or the Alaska Bear for incredible value. Whatever you choose, look for adjustable straps, low profiles, and light-sealing nose bridges to ensure your mask performs as well on your side as it would on your back.
