I currently use MK and i have loved it. i dont sell it, but i do think they have great stuff. you could find more info on this great blog i found. http://www.pinqueblog.com/stylereviews/ . its not a MK direct blog so i feel like you could trust it more.

I don’t know if it will help you as much as it did my but I got an adjustable pillow from https://rem-fit.com/ and from the first night my stomach sleep went down significantly.
