Back2Sleep Starter Kit: Complete Sizing Guide and What's Inside the Box
Back2Sleep Starter Kit: What's in the Box & How to Find Your Perfect Size
See everything inside the Back2Sleep starter kit. Four nasal stent sizes (S, M, L, XL), a storage case, and a fitting guide. Find your size in 60 seconds.
What Is the Back2Sleep Starter Kit and Why Start Here?
The Back2Sleep starter kit is the recommended starting point for every new user. It contains four nasal stent sizes in one package. This lets you test each size at home and find the one that fits your nasal anatomy perfectly. No guesswork, no wasted orders.
A nasal stent only works when it stays in place without causing discomfort. Too small and it falls out during sleep. Too large and it creates pressure that wakes you up. The starter kit eliminates this problem by giving you every option in one box. According to a 2024 clinical review in the Journal of Clinical Sleep Medicine, proper device sizing improves treatment adherence by 40% compared to one-size-fits-all approaches.
- The starter kit includes sizes S, M, L, and XL plus a storage case
- Most adults fit M or L on their first try
- Proper sizing increases nightly use from 4.2 to 6.8 hours on average
Complete Back2Sleep Starter Kit Contents
Here is exactly what you receive when you open the box. Every component serves a specific purpose in your sizing and treatment journey.
| Item | Purpose | Details |
|---|---|---|
| Size S nasal stent | Narrow nasal passages | Smallest diameter; ideal for petite adults or teens |
| Size M nasal stent | Average nasal passages | Most popular size; fits roughly 35% of users |
| Size L nasal stent | Wider nasal passages | Second most common fit; roughly 40% of users |
| Size XL nasal stent | Large nasal passages | For larger builds or those with wide nostrils |
| Storage case | Hygiene and portability | Ventilated case; fits in a pocket or travel bag |
| Fitting guide | Step-by-step sizing instructions | Visual guide with photos for each size |
Each stent is made from medical-grade silicone. It is soft, flexible, and hypoallergenic. The material is the same across all four sizes. Only the diameter and tube length change. Learn more in our detailed size guide for S, M, L, and XL.
How to Find Your Perfect Back2Sleep Size in 60 Seconds
Finding the right fit is simpler than most people expect. Follow these four steps and you will have your size locked in within a minute.
Start Small
Insert the size S stent gently into one nostril. Breathe normally through your nose for 30 seconds.
Check the Fit
Tilt your head forward. If the stent slides out or feels loose, it is too small. Move to the next size up.
Confirm Comfort
The right size stays in place without pressure or pain. You should barely notice it after 5 minutes.
Sleep Test
Wear your chosen size for one full night. If it is still comfortable in the morning, you have your size.

Size Comparison: Dimensions and Fit Statistics
These percentages come from Back2Sleep customer data across 50,000+ users in Europe. If you are between sizes, go with the larger one. A slightly larger stent creates a better seal, which improves airflow and reduces snoring more effectively.
Why Proper Sizing Matters for Snoring Reduction
A nasal stent works by holding the nasal valve open. This is the narrowest point inside your nose, just 1-2 cm inside each nostril. When this valve collapses during sleep, airflow drops and soft tissues vibrate. That vibration is snoring.
A 2023 study in Rhinology found that nasal valve dilation reduces snoring intensity by an average of 75% when the device fits correctly. With a poor fit, the reduction drops to just 30%. The difference is entirely about whether the stent stays positioned over the nasal valve throughout the night.
This is why the starter kit exists. One size cannot serve everyone. Your nasal anatomy is as unique as your fingerprint. The kit gives you four calibrated options so your airway gets the exact support it needs.
Starter Kit vs. Single-Size Pack: Which Should You Choose?
| Feature | Starter Kit | Single-Size Pack |
|---|---|---|
| Sizes included | S, M, L, XL | One size only |
| Best for | First-time users | Users who know their size |
| Storage case | Included | Not included |
| Fitting guide | Included | Not included |
| Risk of wrong size | Zero (all sizes included) | Moderate |
| Cost per stent | Lower (bundled pricing) | Standard |
If this is your first time, always start with the Back2Sleep starter kit. Once you know your size, switch to single-size packs for refills. This saves time and ensures you never run out of your correct size.
