I just wanted to make a recommendation for people who aren't mouth breathers. I use the nose cradle [Moderated. Commercial Link Deleted. Please adhere to posting guidelines] and I've found it to be the least uncomfortable of all the masks! I'm a light sleeper and even with the difficulties of getting used to the CPAP, I wouldn't have been able to do it if it wasn't for the nose cradle. So if you're having trouble or want something more comfortable, maybe give it a try.
