Nemo Tensor Extreme Conditions will be warmer than the All Season.  I find the Tensor series to be a bit more comfortable than the NeoAirs. But she’s already uncomfortable with the Tensor. I would consider instead the Sea to Summit Ether Light XR Pro, which has a high R value and most people have found to be more comfortable than either the Tensors or the NeoAirs.

Check out the new Sea to Summit XR Pro, it’s got a 7.4 R-value, which is actually warmer than the XTherm’s 7.3. I find the baffle design way more comfortable than Thermarest, and the mummy version is a bit wider too, and it’s thicker.

I LOVE the XT R factor (7.1?) the warmth factor definitely has me considering quits over bags now.

Oh-You’re right, my mistake! I just can’t believe how comfortable it is! I’m an old school double closed cell foam pad user and it doesn’t make sense now to use ANYTHING else. I love how the heat radiates back on you immediately when you lay down!

I went with s2s over Nemo and exped because of r factor and that nifty bag it comes with to blow it up. It uses the Bernoulli principle and Venturi effect to inflate the pad.

I have a Sea to Summit Camp Plus long and it's extremely comfortable but it's packed size is not small whatsoever. It takes up a lot of room. I have been recommended the Big Agnes Rapide SL insulated several times now. Little over a 4R value so plenty warm for 3 seasons or possibly even 4 if you have a good bag. Another option is the Sea to Summit Ether light XR Pro insulated if you need a warm pad. That one has a rating over 7.4 R value and it packs down dang small for what it is.

put it in a thin sleeping bag liner or diy your own with a sheet and some shock cord the StS would be a little less slip n slide because of the button weld style, but does not perform as well as it should

I've used the S2S XR Pro and have had experience with the XT Extreme before that. The XR Pro is more comfortable than the TAR Xtherm NXT but not as warm. The XR isn't as confortable as the XT but it is quieter. I sleep on my side but am less prone to shoulder pain. Using a knee pillow helped solve that one for me. I still sleep on a CCF pad, too, but always need the knee pillow. Give it a try!
