Short answer: a fitted jaw-forward guard with a 120-night trial, not a cure
The Somnofit-S is a boil-and-bite mouth guard that gently holds your jaw forward while you sleep, which the maker says opens the airway and reduces snoring. It costs $149.99, is FDA-cleared for snoring reduction, and comes with a 120-night money-back guarantee — you can return it through night 120 even after molding and wearing it. It is a serious, well-made option for throat snoring, but it is not a treatment for sleep apnea, and it takes time to get used to.
How we wrote this: we have not hands-on tested the Somnofit-S. Prices and features below come from SnoreLessNow's official product page, as checked on October 31, 2026, and we say so wherever a claim is the maker's rather than our own finding.

What the Somnofit-S is — and how it works
Short answer: it is a mandibular advancement device — it moves your jaw forward a little, which the maker says keeps the airway open and cuts snoring.
Snoring from the throat happens when the jaw and tongue fall back during sleep and narrow the airway. The Somnofit-S counters that by holding the lower jaw slightly forward. The maker describes it as Switzerland's best-selling snoring solution, now sold in the US by SnoreLessNow, the official US distributor for the Swiss manufacturer. It is made by Oscimed SA from Swiss medical polymers, and the maker lists it as BPA, phthalate, and latex-free.
What sets it apart from a plain boil-and-bite guard, according to the maker, is the patented adjustable bands: they let the jaw move freely, so you can talk and drink while wearing it without it slipping out. The maker lists FDA clearance, which means the device was cleared for snoring reduction — not approved as a treatment for sleep apnea.
Fitting it: boil-and-bite plus the numbered straps
Short answer: you mold it at home with hot water, then pick a strap numbered 1 to 5 for your bite — and give each strap a few nights before changing it.
The fit has two steps. First, the boil-and-bite mold: heated in water, the guard softens so you can press it to the shape of your teeth and jaw. Second, the adjustable straps, numbered 1 to 5, set how far forward the jaw is held — a higher number means a tighter fit. The maker's guide says to start with strap 1 or 2 for an overbite, strap 5 for an underbite, and strap 3 or 4 for a common bite. Wear each strap for at least three to five nights before increasing it: if snoring persists, step up a number; if the pressure on your jaw feels too strong, step down.
Getting used to it takes patience. The maker recommends wearing the guard for one or two hours before bed for the first nights, brushing your teeth before putting it in, and giving yourself 14 nights to adjust. It is normal to manage only a few hours a night at first, according to the maker's own FAQ.
Care is simple: brush the guard with a toothbrush, shake off excess water, let it air dry, and keep it in its storage case. Do not use bleach, ammonia, or mouthwash containing alcohol on it. Replacement adjustment straps are $11.99 on the maker's site if you need a spare set.
What it costs: single, two-pack, and the bundle
Short answer: one guard is $149.99, two cost about $225 with the buy-one-get-one-half-price offer, and the three-product bundle is $197.97.
The pricing on the maker's page, checked October 31, 2026:
| How many | What you pay | What you save |
|---|---|---|
| 1 guard | $149.99 | — |
| 2 guards | About $225 | $75 |
| 3 guards | $299.97 | $150 |
| 4 guards | $374.96 | $225 |
| 5 or more | $449.95 | $300 |
The two-guard price comes from the buy-one-get-one-50%-off offer on the product page. The bulk savings above are the maker's own listed figures. If you want the guard together with the pillow and the nasal clip, the Premium Snore No More Bundle is $197.97, listed as $100 off the $297.97 list total — though the pillow alone is currently $119.99 on its own page, so against today's separate prices the bundle saves $90.

The evidence: what the study actually found
Short answer: the maker cites a study in the journal Sleep Science that found less snoring, better oxygen saturation, and less daytime sleepiness — a real study, but a single one, cited by the seller.
The product page points to a study published in the journal Sleep Science, which, according to the maker, found that using the Somnofit led to significantly reduced snoring, improved oxygen saturation, and less daytime sleepiness. The page does not give the study's authors, year, or sample size, so treat it as one supportive study rather than settled proof.
Two other maker claims are worth knowing, with the same caution. The maker says the device has sold over 500,000 units in Europe as the SomnoFit-S, and that it was named a Top 10 ENT Solutions Provider of 2023 by MedTech Outlook magazine. Both are the maker's own statements, not findings we verified independently.
What the maker reports from users is also just that — reported, not measured by us: less snoring, deeper sleep, happier sleep partners, more energy, improved sleep scores, sharper concentration, and better health. No customer testimonial is used here as proof, because a quote on a seller's page is not evidence.
The honest limits
Short answer: it needs an adjustment period, it can press on the jaw, and it only addresses snoring that comes from the throat.
The adjustment period is the main honest limit. Fourteen nights to get used to a mouth guard is a real commitment, and some people never get comfortable sleeping with something in their mouth. If the jaw pressure is too strong, the maker's own advice is to step down to a weaker strap — which may mean less snoring reduction. A mouth guard also does nothing for snoring that comes from the nose, from sleeping on your back, or from sleep apnea, so it is the wrong tool for those causes. If you are not sure where your snoring comes from, see our guide to SnoreLessNow's full range and which product fits which snorer before buying the guard alone.
The sleep-apnea caution
Short answer: snoring can be a sign of sleep apnea, and no mouth guard treats, cures, or prevents it.
This matters more than any feature list. Loud snoring with gasping or pauses in breathing, waking up unrefreshed, daytime sleepiness, morning headaches, or high blood pressure can all be signs of sleep apnea — a condition in which breathing repeatedly stops during sleep. The Somnofit-S is FDA-cleared for snoring reduction, not as a treatment for sleep apnea, and it does not cure or prevent any disease. If any of those signs sound familiar, see a clinician — and ask about a sleep study — before relying on any anti-snore product, including this one. A mouth guard can make the nights quieter while the underlying problem goes unexamined, and that is the one outcome to avoid.

Frequently asked questions
Does the Somnofit-S really stop snoring?
The maker says it reduces snoring by holding the jaw forward, and cites a study in the journal Sleep Science that found significantly reduced snoring. We have not hands-on tested it, so we cannot confirm the effect for any individual — and it only addresses snoring that comes from the throat, not from the nose or from back sleeping.
How long does it take to get used to?
The maker says to give yourself 14 nights to adjust, and to wear it for one or two hours before bed at first. It is normal to manage only a few hours a night in the beginning, according to the maker's FAQ.
Can I return it if it does not work for me?
Yes. The maker offers a 120-night money-back guarantee: you can request a return through night 120 even if the guard has been molded and worn.
Can I talk and drink while wearing it?
According to the maker, yes — the patented adjustable bands let the jaw move freely, so you can talk and drink without the guard slipping out.
Verdict: a well-made guard for throat snorers who will give it two weeks
If your snoring comes from the throat, you are willing to spend two weeks getting used to a mouth guard, and you want the strongest single product SnoreLessNow sells, the Somnofit-S is a reasonable buy — especially with the 120-night return window, which removes most of the risk. If your snoring comes from a stuffy nose or from back sleeping, start with the cheaper fix for that cause instead. And if you have any sign of sleep apnea, see a clinician first; no mouth guard replaces that conversation.
