I concur with highly recommending the Resmed memory foam airsense for her mask. No leak, very comfy, doesn’t make pressure marks on my face in the am.
I am a side sleeper and find the dreamwear is very soft and Non-confining. You need to make sure it is snug enough so it doesn’t shift around but that is ok since it is comfy. I tried about 5 masks before FINALLY finding this one that doesn’t irritate my poor nose or upper lip. The dream wear is great.
