Had this since 2008 and using it with second child. It's one of the few items we have kept from then.
It works fantastic to create a safe bed-sharing environment, especially in hotels or while staying with family, where beds are not set up for safe co-sleeping and falls/entrapment could occur.
It's BIG and bulky to travel with, but I was able to stuff it in a duffel bag.
The previous reviewers con about making the bed has not been an issue for us. I leave it (because I'm not huge on making beds, nobody sees our bed) or roll it up to one side. If I were worried about the aesthetics of the bed, I could roll it up and put it along the head of the bed, behind the other pillows. Voila, it's a long, decorative pillow or makes the other pillows stand up better.
It could be wider so you never end up laying on the seem (but that would make it even bulkier).
The pad is machine washable, the actual pillow is not.
It's durable and has lasted us this long!
I remember one claim on the website about not waking up in wet pee/spit/milk. I've no idea what they're on about there. It doesn't stop you from getting wet. It's not a puddle, but it still gets wet.
Works great for creating a safe bed sharing environment though!
