I got it because I saw generally after research that it helps with reflux. It works not only during sleep but also when I lie down and browse on my phone, for example, I feel more comfortable. Also, because it is very firm, I feel that it supports my back. Very good choice. The outer cover comes off and can be washed.

I bought it looking to find a way to reduce my snoring and save my wife's nervous system, and it had an immediate effect, practically eliminating the snoring. They refer to it as a pillow, but it is essentially a firm wedge-shaped mattress pad on which you place your regular pillow, at least that's how I use it for snoring. It's good to also place a second pillow under your knees, it functions somewhat like a brake to prevent you from sliding down during sleep. Also, it doesn't fit in a pillowcase, I wrapped it with a small sheet and it's fine.

The pillow is quite firm and does not sink. I bought it to be used for a person with gastroesophageal reflux during sleep, but it gives a very steep incline, maybe a smaller one would be more suitable. I give it 2 stars because the pillow cover is of poor quality fabric and the zipper broke in one week.

Very convenient and quite economical, be careful it is slightly smaller than some photos I had seen, but it is generally large
