Sleep Position Trainer for Sleeping On Your Side | Side Sleep Trainer | Snore Stopper | Anti Snoring Device | Lightweight, Comfortable, Effective in Reducing Supine Sleep Time

I've been using this for several months now and have been very pleased with how it's keeping me off my back. I easily adjusted to sleeping with it. I had tried using two other methods for avoiding sleeping on my back, and this has been the most comfortable and effective for me.

For those reviewers who found that this didn't work well: perhaps your mattress is too soft, so that the ball sank in and wasn't uncomfortable enough to keep you on your side. Lose the mattress topper, or get a firm one. This thing WORKS. Even if you succeed in rolling onto your back and getting in a couple of snores, the discomfort will catch up to you pretty quickly on a moderately firm mattress (and yes, I did this experiment myself).It's hard to believe I'd write such a positive review for a product that has made me so miserably uncomfortable and changed a deeply engrained, lifetime habit and preference - starting on night one. But apnea is deadly, and it turns out that I want to live to a healthy old age slightly more than I want to sleep on my back. The Snore Lab app told me that I snore like a wild boar. A sleep study told me that I stop breathing 100 times per night, nearly always when I'm on my back. So it was CPAP or side sleeping. This device is cheaper than CPAP, so I tried it first. It's been a month, and the change is profound. Yes, my neck, back, and hips are complaining a lot, since they are not used to this position, but it's getting better and I'm tinkering with pillows.So if you're uncomfortable initially, well, yeah, you're supposed to be! It hurts to roll onto a big hard ball! If you need more discomfort, there's room for an additional tennis ball in there with the cork ball. I will say that the straps are intended for a bigger person than I am, and I need to tighten them regularly, as they tend to slip. Also, the shoulder/over the head part is too loose, so I do have a few problems with stability. But it is far more secure, and comfortable to wear, when snug than I imagined. This thing is totally worthwhile!

But not so much a great outcome. The ball had to be padded with extra socks for comfort.

I am a retired Family Medicine physician suffering from sleep apneaI tried t-shirts but this vest is light, airy, compact thus easy to take on travels.I switched out the cork ball included (too hard & painful) for a rubber lacrosse ball.My apnea spells have decreased somewhat as recorded by a nighttime oximetry sensor that I wear on left 4th finger. (EMAY pulse oximeter $68.98)Update: after 7 months continuous nighttime use, my desaturation times decreased from 7% per night down to zero per night. PTL.

Seems to work great, had it about a week. The ball wakes me up a bit when I roll onto it and it hurts my back - I suppose this is part of the design, it's supposed to be uncomfortable so you move but damn. Thinking about switching out the ball for a tennis ball. The harness thing itself is comfortable, adjustable, and holds the ball in place. I'd recommend it! Just wish I could be more comfortable wearing it when I sleep.

My husband found this comfortable to wear, and it does have adjustable straps that prevent it from sliding around too much like the SlumberBump we tried previously. But I still find him sleeping on his back snoring, the ball digging into his back without waking him up.One solution might be to tie a thick towel around the ball so he physically can’t roll onto his back. But for $60 the ball should be so uncomfortable that he can’t roll over onto it without waking up, and it’s not preventing him from sleeping on his back.

Keeps me off my back for sleep apnea prevention. Well made, easy to use, simple and does the job.Took a week or so to get used to but now not the least bit of bother.If you have sleep apnea that is completely position-dependent, I think this can avoid needing a CPAP machine.

Really uncomfortable and didn't work!
