So i tried the nasal pillows for the dreamwear and have to say it fits nicely, maybe a little less comfortable than the cushion but i could move around with a leak starting so thought it was an improvement for someone like me who moves around alot - read as pushed around in bed by a beagle and a chihuahua allnight!

But i notice late in the night the sound of air escaping, and went to reposition the nosepiece and just like the cushion it seems so pliable that it wont sit still anymore, and feels like its not as rigid. Could the air temperature from the heated hose and my breathing be warming it up enough for it to just be more malleable? Otherwise great night still get irritation to my nose to be able to go to sleep without constantly adjusting the mask was a great improvement.

Thanks

I changed to the large pillow to fix this instead of the medium I was using, if you are talking about the Gel Pillow cushion for the Dreamwear mask.

Yeah, the trouble is im guess the nasal cannulas get bigger with each size and they just about fit now with the medium as i had to move up from the small due to not getting enough air. It seems fine until ive been using it for several hours.

If it's too small, it'll shift over on the rim of your nostrils, and actually try to go up into your nostrils and leak.

I had that issue, that's why I switched to the large size.

The thing is and unless im misunderstanding you it fits perfectly most of the night, but by about 5 hours in its suddenly not sitting still at all. Even the cushion does this after a number of hours in use each night. its like it becomes way soft and doesnt hold its shape. Next nights it back to normal.

No, not really, Silicone is a cured 'rubber' compound. It's good up to around 550 degrees F... which is why bakers love silicone baking mats, and cooks love silicone spatulas and such... it won't melt at high heat like plastic will.

Believe it or not, your (our) head(s) shrink during the night due to water lose. The mask I'm using right now has the same issue. My head shrinks by early morning, and the fixed headgear is looser.

That doesnt surprise me and i wonder if the headgear is half there doesnt seem to be much leeway between tight and just right - At the moment i tuck it under my 'wild' hair at the back but it moves alot and by morning i think the pressure of my head against the pillow is all that holds it on.
