## Overview

The WoodyKnows Side-Sleeping Backpack is a large, breathable, and adjustable sleep position trainer designed to alleviate snoring caused by throat obstructions. Featuring a 3-point fixation system and inflatable airbags, it keeps you comfortably off your back all night, promoting healthier breathing and better sleep quality. Ideal for adults with back widths over 16 inches, this washable, ergonomic device offers a customizable fit and a 3-month warranty on airbag replacements.

## Description

Product Description This backpack is a side-sleeping trainer for BACK sleepers and STOMACH sleepers. Research shows that 80-85% of snorers only snore while sleeping on their back. This product helps maintain side-sleeping position and develop the side-sleeping habit within two months. The unobstructed airway will allow you to breathe smoothly and sleep peacefully. It is big enough to keep you off your back at night, thus you will not end up sleeping on it or get your spine hurt in the way that wearing a small or hard supporter would. Three-point fixation on the shoulders and the waist to avoid shifting and sliding around over time. You can adjust the air capacity of the airbag to find the most suitable sleep position. Two sizes are available. Measure your back width between your armpits but not including your arms. Large size is for people with a back width larger than 16 inches (40 cm). Medium body sized people are recommended to choose the Large Size Backpack.

Review: Lifesaver if you have sleep apnea and don't want to mess with CPAP - I bought this about a year ago and have used it every night since. It had a slight odor from the foam, I washed it in the washing machine and that went away as soon as it dried (line dry...not dryer). So in a day I was good to go. If you inflate the air bladder full, you CANNOT sleep on your back, it basically keeps you ninety degrees to the bed. I found that too much. So I let around half the air out of the bladder, and with that setting I can roll from one side to the other, and I could sleep somewhat on my back, but if I do my head is elevated and I don't snore. However, 95% of the time I don't sleep any on my back. The point is, you can adjust the bladder to give any level of partial or none at all back sleeping. It took a day to get the bladder set right, and since then I've worn it every night, never needed to reset it. Likewise, it took a day to find the best use of the straps for me. I like the backpack style just over the shoulders, not X'd across the chest. I find it more comfy, though either works fine. So, by two days in I had it all adjusted and ever since then it takes about 15 seconds a night to put it on last thing before going to bed. You just fasten the Velcro belly strap and lie down. The Velcro, the fabric, the bladder, everything still working like new after, as I said, almost a year. Likewise a few seconds when I get up to set it where it lives. I find it doesn't interfere with sleep quality at all, or ease of going to asleep. It's well made and does the job. I say it's a lifesaver since I sleep with a recording pulse oximeter (Wellvue "Sleepu" available from desertcart, finger ring sensor and wrist strap for device, highly recommended) and it was showing me an ODI of 15 or so, and sometimes SpO2 as low as 61, which was scary. Since I started using the backpack a typical ODI is around 0.5 (no apnea) and typical minimum SpO2 is over 90%. [Doc says you worry when it's under 88% for 5 minutes...which it was, pre-backpack and never since.] I recently finally had a full-blown sleep study where he confirmed the backpack has solved my issue. Highly recommend it for sleep apnea. Note: For "obstructive" sleep apnea, where the problem is lying on your back and your tongue etc. interfering with your airway. There is also "central" sleep apnea in a minority of people where the issue is malfunctioning nerve control, as I understand it. I don't think it would solve that problem. Consult a doctor if you have any doubt what your issue is or if you have an issue. But this puppy works great to comfortably let you sleep on your side, or partially on your back.
Review: Seems to work better than other solutions to nighttime snoring - I have only used this for two nights so I can't say how well it will work in the long run. I am only 5'2", 120 lbs and bought the large size and am glad I did. The inflatable pillow really keeps me off of my back. I was afraid the smaller one would not have done the job. I have used two configurations with the shoulder straps and have not decided which arrangement works best for me. The backpack does keep me off of my back so my snoring is now very minimal and only occasional. I use an app on my phone which tracks my snoring and my Apple watch has not detected any elevated breathing disturbances. If the backpack continues to help me to not snore or have breathing disturbances, I will be very happy. I had been using a wedge pillow behind my back to keep me on my side which helped when it stayed in place but some mornings, I awoke to find the wedge off to the side. This backpack idea is the best I've found. It seems to be well made and fairly comfortable. It is on the expensive side but if the pillow maintains air and my results stay good, it will have been worth every penny. Some reviewers stated there was a smell to the unit. I did not find that the case. As for ease of use, it is easy to put on and the Velcro seems good.

## Features

- This backpack features a three-point fixation on the shoulders and the waist to avoid shifting and sliding around over time, and it equipped with lightweight and easy to carry airbags.
- This is not effective for all snoring situations. The side-sleeping position with the help of this device can only help alleviate snoring caused by throat issues. This product helps you train yourself to develop a side-sleeping habit quickly so that the tongue, soft palate, and loose throat tissues will not fall backwards, blocking the airway.
- It is big enough to keep you off your back at night, thus you will not end up sleeping on it or get your spine hurt in the way that wearing a small or hard supporter would. You can adjust the air capacity of the airbag from half full to full to find the most suitable sleep position.
- Please remember that airbags are consumables and will not be used forever due to usage and pressure. You can send us a message for a free airbag replacement within the 3-month warranty period. Please put the airbag in if you choose to return.
- Measure your back width between your armpits but not including your arms. Large is more suitable for people with a back width greater than 16 inches (40 cm). The wearing effect varies from person to person, and it cannot be guaranteed that the side sleeping backpack will fully fit the body.

### ⭐ DO NOT BUY THIS DEFECTIVE PRODUCT
*by B***H on April 19, 2026*

This product is a shocking ripoff, preying on people hoping for a solution to sleep apnea. I opened the package, inflated the insert, and within 15 minutes it had lost all air, even without touching it, much less rolling over on it. You can't fill the backpack with towels because it becomes so heavy it is unwearable. I can't believe I was taken in by this. UPDATE: I filled the backpack with a roll of paper towels. But the straps of the backpack are so hard, stiff, inflexible, and scratchy, that it is near impossible to wear them as tight as necessary to prevent the backpack from slipping to the side. Backpacks for hiking with comfortable front straps have been manufactured for DECADES! I own several. Why could WoodyKnows not have used this know how to make backpack straps that mold to the human body and are comfortable??
