200+ SleepZee Reviews Analyzed - Legitimate or a Scam?

Many shoppers are looking for SleepZee reviews before deciding whether or not to give their mouthpiece a try. And as you will find out reading this article - that's probably a good idea.

As of late 2025 the company had a 1.9 star average rating on TrustpiIot (based on 21 reviews) and while not all these reviews come from verified purchases, this definitely warrants a more in-depth review.

Also, there is a mattress brand called "Sleep EZ" and some shoppers seem to be confused by that. To our knowledge this mattress brand is not in any way associated with SleepZee!

In this article we summarize the verdict on SleepZee. We look into SleepZee’s performance, the level of comfort provided, and their return policy.

SleepZee sells an anti-snoring mouthpiece that is a boil-and-bite oral appliance intended to reduce snoring by gently advancing your lower jaw. The rationale for this approach is that shifting your jaw gently forward as you sleep helps keep your airways open - and thereby prevents the soft tissue at the back of your throat from connecting. This then helps reduce or eliminate snoring.

SleepZee's anti-snoring devices are marketed as a non-invasive, drug-free, use-at-home option. Manufacturer claims typically mention latex-free, BPA-free materials and adjustability for a personalized fit.

So much for the theory.

Note: Some online mentions reference FDA clearance. Always verify claims on the official product page and current labeling before purchase.

When researching a new snore-reducing product, legitimacy is a key concern. While SleepZee is a real product that you can purchase. Besides looking into SleepZee reviews, a deep dive into consumer protection agencies reveals concerning patterns that potential buyers must be aware of.

The Better Business Bureau (BBB), a nonprofit organization that rates businesses and helps resolve consumer complaints, states that "SleepZee is NOT a BBB Accredited Business" and, as of December 2025, flags the company with an has issued an "F" rating for SleepZee. This is the lowest possible BBB rating and is typically assigned due to a high volume of unresolved complaints and a failure to respond to consumer grievances.

BBB states specifically provides that the reasons for this rating are (Source):

• Failure to respond to 3 complaint(s) filed against business 

• 5 complaint(s) filed against business 

• Length of time business has been operating

Unlike reputable US-based sleep companies that maintain accreditation, this low rating serves as a significant red flag for buyers expecting accountability.

We at VitalSleep for instance, are proud to have received an A+ rating by the BBB.

When reviewing SleepZee reviews on popular review platforms such as TrustpiIot, many consumer complaints and unfavorable reviews mention the SleepZee return policy.

On its website, as of December 2025, SleepZee states that "We offer a 30-night money-back guarantee. If you are not satisfied with the ant-snoring device, contact us and you can return it within 30 days for a full refund."

However, dozens of verified reviews highlight a critical catch in the fine print:

In SleepZee reviews many customers report that when they attempt to return the device because it didn't fit or was uncomfortable, their requests are denied citing "hygiene reasons."

According to these SleepZee reviews, the company often claims that once the box is opened or the seal is broken, the product cannot be returned. Since you must open the product to try it, this effectively nullifies the guarantee for many users.

We cannot verify the validity of these accusations also as of December 2025 we could not find any information regarding a "hygiene policy" on the SleepZee website.

In its official returns policy available on the SleepZee website the company however states that "In general, only products with proof of functional defects may be refunded. Also, to be eligible for a return, your item must be in the original packaging." (as of December 2025).

This stands in stark contrast to companies like VitalSleep, which honor returns even after the product has been used. Be aware that you cannot test a mouthpiece without wearing it and also check newer SleepZee reviews to verify if things may have changed.

Based on an analysis of over 200 SleepZee reviews from third-party sites (not just the curated testimonials on their own website), here is what you can realistically expect.

• Price: The device is often discounted and sold at a very low price point (sometimes below $30), making it an attractive "impulse buy" compared to dentist-fitted devices.

• Basic Mechanics: For some users with large jaws, the mandibular advancement mechanism does technically work to move the jaw forward.

• Airflow Vents: The device includes visible holes for mouth breathing, which is necessary if you have nasal congestion.

• Ambiguous Return Policy: As noted above, the "Money-Back Guarantee" may not always be honored and opening the product (which is required to test it) may mean that it cannot be returned.

• "One Size" Issues: Many users report in SleepZee Reviews that the device is excessively bulky and too large for an average mouth, leading to gagging or severe jaw soreness. Unlike adjustable devices that let you control the advancement level, the SleepZee mouthpiece is often described in SleepZee reviews as "static fit". Note that these might be very personal experiences that do not apply to you.

• Potential Customer Service Ghosting: A recurring theme in complaints is the difficulty in reaching a human support agent. Many users report that support emails go unanswered, or that users receive automated responses denying refunds. We cannot independently verify whether or not these claims are accurate.

• Durability Concerns: Reports of the material hardening or losing its mold capability after a few weeks are common among purchasers. We can again not verify these claims but only reiterate information that we have found conducting research on the internet going through hundreds of SleepZee reviews.

Expect tiered or multi-pack pricing. Some sellers advertise free shipping and a money-back timeframe. Because return shipping may be on you, factor that into total risk. Prices and policies change: confirm final terms on the checkout page before you buy.

While we believe that it is important to solve snoring issues, we also stress the importance of finding a reliable and effective anti-snoring device. And with all the options available (Related articles: Honex anti snoring mouthpiece, our analysis or Daybreak Reviews and Quiet lab reviews analyzed), we cannot in good conscience recommend a product with an "F" rating from the BBB and an alleged track record of denying refunds. The risk of purchasing a device that you cannot return, especially one that goes in your mouth, is simply too high. If you still want to proceed and purchase a SleepZee product, we recommend that you contact the company beforehand to clarify whether or not you will be able to return a product after you have tested it - in case it's not working for you.

Considering alternatives? Compare fit adjustability, return clarity, and total cost (including potential return shipping) before you decide.

1. Fit carefully: Follow boil-and-bite timing, start with minimal advancement.

2. Expect an adjustment week: Soreness and drooling often fade with time.

3. Remold if needed: A better seal and alignment can improve comfort.

4. Clean daily: Mild soap and cool water; avoid harsh abrasives.

5. Track outcomes: Ask your partner or use a snoring app to measure progress.

6. Layer lifestyle changes: Side-sleeping, less alcohol before bed, weight management.

7. Get help if pain persists: Consult a dentist or sleep professional.
