This Isn't Really About the Snoring.

Most couples don't talk about what it's actually costing them. The guest bedroom that started as temporary. The morning that begins with an argument before anyone's said a word. The intimacy that gets a little harder to reach with every sleepless night. Snoring is the #3 cause of divorce in the United States — not because of the noise, but because of what the noise does to two people over time. Beside™ was built for the couple that wants to come back to bed. Not just stop the sound.

Why Nothing Has Worked?

Every snoring solution you've tried was built on the same assumption: that snoring is a breathing problem. Something to fix at the nose, the throat, or the mouth.

That assumption is wrong. And it's why nothing worked.

When you fall asleep, your jaw relaxes and drops backward, pulling your tongue with it. Your tongue partially blocks your airway. Air forces through the narrowed passage and vibrates the soft tissue of your throat. That's the sound. The problem isn't your nose. It's the position of your jaw.

Nasal strips widen your nostrils. The blockage isn't in your nostrils.

Throat sprays lubricate the airway. The problem isn't friction. It's geometry.

Chin straps keep the mouth closed. But that doesn't change where the jaw sits.

CPAP works by forcing pressurized air through the blockage rather than removing it. But half of all users quit within three years. If you're one of them, that's not a personal failure. It's a documented pattern.

The only solution that addresses the actual cause moves the lower jaw forward while you sleep. Gently, precisely, held in place all night. Sleep dentists have been doing exactly this for decades, at $2,000 to $6,500 a session. Beside™ does the same thing.

  • Mold It

    Boil the device for a 1-2 minutes, then bite down to create an exact impression of your teeth. Unlike generic one-size devices that shift during the night, Beside™ fits your mouth specifically and stays exactly where you set it until morning.

  • Adjust It

    Using 1mm increments, advance your lower jaw until you find the position that opens your airway without causing discomfort. Every jaw is different. Some people need 2mm. Others need 5mm. You dial in your position over the first few nights. Not too little, not too much.

  • Sleep Beside Them

    Most users notice the difference the first night. The jaw holds. The airway stays open. The room goes quiet. What comes next is something most couples in this situation haven't experienced in a long time: sleeping in the same bed, through the night, actually rested.

Real Stories From Real Couples:

  • Karen M., Partner of snorer · Dallas, TX

    My husband snored for nine years. I stopped counting how many nights I moved to the couch. The first night he wore this I lay there in the dark just listening, and I realized I was waiting for the sound to start. It didn't. I don't know how long I stayed awake just listening to the quiet. Long enough to cry, which is not something I do easily. We've been in the same bed every night for five months. I keep telling my sister she doesn't have to just live with it.

  • Diane B., Partner of snorer · Nashville, TN

    I want to be specific because I know how skeptical I was. I had bought him two other mouthpieces before this one. The first fell out every night, which he thought was funny until I stopped finding it funny. The second caused enough jaw pain that he quit after five days, and I couldn't blame him. We'd been sleeping in separate rooms for over a year by the time I tried this. I almost didn't order it. What got me was the guarantee. I figured the only thing I'd lose was another month of hoping. The first week his snoring dropped noticeably but wasn't gone. Week two it was gone. He wears it every single night since. I stopped doing the math on how many hours of sleep I was getting. I don't need to anymore.

  • Tom H., Snorer · Columbus, OH

    My wife handed this to me and said she needed me to actually try it. That was her exact wording. I'd already failed with a chin strap that did nothing and another mouthpiece that left my jaw sore for three days straight, so my expectations were low. The first few nights I woke up with some stiffness and almost quit. I'm glad I didn't. By the end of the first week my wife told me she slept through the night. She said it like she was reporting something she didn't quite believe yet. I've been wearing it every night for four months. I'm not someone who writes reviews. I'm writing this one.

Everything You Want to Know Before You Try It:

I tried a mouthpiece before and it hurt my jaw. Why would this be different?

Jaw pain from a mouthpiece almost always comes from one of two things: the device was fixed at a position that was too aggressive for your jaw, or it didn't fit properly and was forcing your jaw to compensate all night. Beside solves both. The boil-and-bite mold creates a custom fit specific to your teeth, so the device isn't fighting your jaw to stay in place. And the 1mm micro-adjustment means you start at a gentle position and move forward gradually until you find the point that works without causing discomfort. Most people who experienced jaw pain with other devices find that Beside feels noticeably different within the first week.

Will it fall out during the night?

This is the core problem with generic one-size mouthpieces, and it comes down to fit. A device that isn't molded to your teeth sits loosely in your mouth. It shifts, it slips, and by 3am it has either fallen out or moved to a position where it isn't doing anything. Beside's boil-and-bite process creates an exact impression of your teeth specifically. The device fits your mouth the way a custom retainer fits yours and nobody else's. It stays where you set it all night.

Is there an adjustment period? What should I expect the first few nights?

Yes, and we want to be honest about this because it's the reason a lot of people quit something that would have worked. The first three to seven nights, your jaw is holding a new position through the night. Most people notice some mild stiffness or soreness in the morning during this window. This is normal and it passes as your jaw muscles adapt to the new position. By the end of the first week most people stop noticing the device is there at all. The mistake is quitting on night three before your jaw has had time to adjust. If you experience discomfort in the first week, try dialing the advancement back by 1mm rather than stopping entirely. Give it the full adjustment window before you decide.

Will it work if I sleep on my side?

Yes. Beside works regardless of sleep position. The mechanism is jaw position, not body position. As long as the device is in and holding your jaw forward, the airway stays open whether you are on your back, your side, or your stomach. The custom mold is what makes this possible. Because the device fits your teeth specifically, it maintains its position and holds the jaw advancement through the night no matter how much you move.

Will it work if I breathe through my mouth?

Yes. Beside is designed to allow airflow through the mouth. The device holds the lower jaw forward without sealing the lips or blocking the oral airway. If you are primarily a mouth breather at night, you can still use Beside comfortably and the jaw advancement mechanism works exactly the same way.

Why is this so much cheaper than what my dentist sells?

The mechanism is identical. Custom mandibular advancement devices from sleep dentists use the same jaw advancement principle, the same custom fit process, and the same incremental adjustment approach that Beside uses. The price difference comes entirely from overhead. A dental device requires an office visit, impressions taken by a clinician, a lab fabrication fee, a follow-up appointment, and the markup that comes with all of it. Beside does the fitting at home in about five minutes and ships directly to you. The mechanism hasn't changed. The office visit has been removed.

Is it safe to use long-term?

Mandibular advancement devices have been used in clinical and dental settings for decades and have a well-established safety record. The most common concern people raise is bite shifting, which is associated specifically with fixed, non-adjustable devices that lock the jaw in a single aggressive position for extended periods. Because Beside is adjustable, you control the amount of advancement. Using the minimum effective position rather than maximum advancement significantly reduces any risk of bite-related discomfort. If you have existing jaw issues, TMJ, or significant dental work, we recommend checking with your dentist before use.

How long does it last before I need to replace it?

With regular cleaning and normal use, most customers get six to twelve months from a single device. How you care for it makes a significant difference. Rinse it every morning, clean it with a soft brush and mild soap or a denture cleaning tablet a few times a week, and store it in the case provided rather than leaving it exposed. We recommend replacing it when you notice any degradation in the fit or the material. A device that fits correctly is a device that works correctly.

What if it doesn't work for me?

You have 60 nights to find out. If Beside™ doesn't stop the snoring, if you cannot tolerate wearing it, if it causes discomfort that doesn't resolve, or if it simply doesn't work for any reason at all, contact us and we will refund every dollar. No conditions, no fine print, no questions that make you feel like you have to justify yourself. The guarantee exists because we know this market has been burned before, and the only way to ask someone to try again is to remove the risk entirely. The 60-night window also gives your jaw the full adjustment period it needs before you make a final judgment. One week is not enough. Sixty nights is.

Try It for 60 Nights. Risk Absolutely Nothing.

If Beside™ doesn't stop the snoring, if you can't sleep with it, if it causes discomfort that doesn't resolve, or if it simply doesn't work for any reason at all — contact us and we will refund every dollar. No conditions. No fine print. No questions that make you feel like you have to justify yourself.

We offer 60 nights because one week isn't enough time for your jaw to fully adjust and for you to find your exact position. The full window exists so you can give it a genuine chance rather than a rushed one.

The only real risk here is doing nothing. Another year of the guest room costs more than 60 nights of trying something that might give it back.

What If Tonight Was Different?

60 nights. No conditions. No risk. You already know what doing nothing looks like.
