I've used a 3P and a 4p with my bf. It was the perfect size for me in my msr elixer 3. My bf and I got the sea to summit version in a double for both of us to use and it had leaks within the first two weeks so I'm a big fan of how well my thermarest has been holding up
Exped MegaMat 15 or one of its clones (Sea To Summit Comfort Deluxe, Big Agnes Captain Comfort, Nemo Roamer 3D, ALPS Outback Mat etc). Well worth the money. You will want to get an air pump for this. For the Exped mats the Megapump is totally worth it.
Get the sea to summit comfort deluxe double Its unbelieve comfier than my 2000$ mattresss
Samw with my sea to summit absolutely unbelievable how comfy it is.
A non-insulated blowup air mattress like you buy at Walmart will be much colder than the ones designed for camping. Exped and Thermarest both make great home mattress-like pads. I have a Sea to Summit Deluxe and it's wonderful - I bought it over an Exped/Thermarest because it comes with a lifetime warranty.
Since weight isn’t a concern and you’re staying in one place, comfort should absolutely come first. The Exped Megamat LXW is kind of the gold standard for plushness — it’s wide, super supportive, and feels almost like a real mattress. It’s bulky, but since you’re not carrying it, that doesn’t matter much. The Sea to Summit Comfort Deluxe is also great, but the shorter length might be annoying at your height. Your feet will probably hang off a bit unless you sleep curled up. The Comfort Plus 8cm version is nice too, but it’s more of a premium backpacking pad, not a “sleep like home” pad. If you want to sleep well all week, go with the Exped. You’ll wake up rested and not sore, which matters a lot for long ski days. The S2S pads are decent backup options, but you’ll probably end up wishing you went for the thicker, wider Exped after the second night.
We use fold up carton type mats as our base. Then in our tent we have Sea to Summit self-inflating bed rolls. Our kids have the same base and use Therm-o-rest self-inflating ground mats. We find as long as we stay on the self-inflating mats, we’re pretty comfortable. The ther-o-rests are almost 20 years old and still in great shape. We upgraded to Sea to Summit because they fold up so small for backpacking
