Question Other Side Sleepers Asked
"Will this actually stay on when I roll over?"
Yes. Unlike drape-style masks, Deeply uses an adjustable-strap anchor system that locks in place. The 7-zone weight distribution keeps pressure even no matter your position.
"Will the weight give me a headache?"
No. We use 0.6 lbs (9.6 oz) based on 2024 research showing 0.5-0.75 lbs is optimal. Heavier masks (12-15 oz) cause headaches after 20-30 minutes.
"I'm a stomach sleeper. Will this work?"
The thin 15mm profile works for stomach and side sleepers. However, if you sleep 100% face-down, a traditional eye mask may be more comfortable.
"How is this different from other weighted masks?"
Most weighted masks are designed for back sleepers. They fall off or shift when you turn. Deeply is engineered specifically for side sleeping with a thin profile and adjustable strap system.
"Can I cool this for migraines?"
Yes. Place in freezer for 30 minutes. The microbeads retain cold for soothing relief.
"How fast will my order ship?"
Your Deeply mask ships fast:
- Processing: 24-48 hours
- International Delivery: 6-12 business days
- Tracking: Provided automatically once shipped
We know you're excited to finally sleep through the night—we'll get your mask to you as quickly as possible.
"What's your return policy?"
30-day money-back guarantee. If Deeply doesn't work for your side sleeping, return it. No questions asked.
The World's First Weighted Sleep Mask for Side Sleepers
Most weighted masks fall off the moment you roll over. Deeply ONE stays on.
Built For How You Actually Sleep
68% of us sleep on our side. Yet every weighted mask is designed for back sleepers—drape styles that slip off, bulky eye cups that dig into your temple, weights that shift when you move.
Deeply ONE is different. It's engineered specifically for side sleeping with three core principles that make it actually work:
Adaptive Weight Distribution
7 zones of precisely calibrated weight (0.6 lbs total) move with you as you shift positions. The calming pressure that quiets your racing mind at 11 PM is still working at 3 AM—even after you've rolled over twice.
Thin 15mm Side-Sleeper Profile
Unlike bulky masks (25-30mm), our streamlined design doesn't crush your temple when you turn. This is how you sleep through the entire night without pressure pain waking you up.
Adjustable Anchor Strap
Stays locked in place all night. Total darkness from lights out to alarm—no light leaks at 2 AM, no waking up with it on your pillow.
Our Promise
Try Deeply ONE for 30 nights. If it doesn't stay on when you roll over, send it back. But it will.
