Side sleep enforcer for positional apnea
I am a notorious back sleeper. Over the years, I have tried several commercial and homemade alternatives tennis balls, spikes, backpacks, etc.), but none prevented me from sleeping on my back. They can be easily twisted and tossed sideways during sleep or not obstructive enough to prevent one from sleeping on them; they perform poorly on a very soft mattress you want to use for side sleep to protect your shoulder.
The desired design must possess two main features: (i) the obstructive element should be large enough to prevent sleeping on it, and (ii) it should not be moved sideways from your back. To satisfy point (ii), I altered my mountain climbing gear, which has anchoring points on both my shoulders and my thighs. To meet point (i), I fixed a basketball on the back of it. I have used this device successfully for years. But it consumed a lot of space in my luggage and was heavy, too.
Here are the photos of the improved device, which I have been using for over a year. The plastic box can be opened and filled with your staff during travel. It is impossible to sleep on your back even when you use a 3-inch thick memory foam on your mattress.
