Nyxmate is a position trainer that helps you learn to sleep on your side instead of on your back. At only 45 grams, it gently guides you away from snoring. After 3–4 months, most users have trained themselves to sleep on their side without it. If you fall back into the habit of sleeping on your back, you can use the ball again for a period to reinforce the training.

Like any new habit, adapting to Nyxmate takes time. In the beginning, the sleep ball may feel uncomfortable—but that’s the point. Each time you notice it, it’s because you’re about to roll onto your back. Over time, this will happen less and less.

Some users may find that the ball comes off during the night. However, if properly attached to your clothing, it should not fall off on its own. More often, it happens because people unconsciously unscrew it in their sleep—a natural reaction to removing something that feels disruptive. If this happens, don’t see it as a failure—it’s part of the training process. In the beginning, it’s more important to wear the ball for a few hours each night than to worry about keeping it on the entire night. You can also agree with your partner that they can reattach the ball if it comes off during sleep.
