I ordered the Therm-a-Rest LuxuryMap Self-Inflating Foam Camping Sleeping Pad, Large - 25 x 77 Inches - from Amazon. It's warm and very comfortable. Very important to be insulating on the bottom, especially as temps start dropping.

Two separate Thermarest Mondoking XLs side by side - different air pressures - no waterbed affect when one of us moves/rolls over. Kelty doublewide sleep system (bag).

MondoKing has worked really well for 3 plus yrs. Or cot plus basecamp.

Megamat Ultra and the Thermarest Neoloft are comparables. Def not ultralight but I use the Thermarest on backpacking trips, not thru-hikes, and love it. I'm a big guy and the Thermarest is comparable to my MondoKing and Exped MegaMat Duo. The Ultra will work well for you.

We also have just two car camping pads side by side! Enough for snuggles without disturbing each other as much. We have Mondo King pads/mattresses. Not sure if they still make them but feel like they were less expensive than the Expeds seem. And option to still use it for a solo trip.

We sleep on two Mondo Thermarest pads strapped together. They’re 5” thick and wider than conventional Thermarests. Very stable and comfortable to sleep on.

Buying a nice 4 inch sleeping pad (I have a thermarest mondoking) five years ago was a game changer for me when it comes to car camping. I love that damn thing so much, I have no trouble sleeping on a traditional thin thermarest but the 4 inch one is straight up luxurious. It's not even in the same universe as a crappy walmart air mattress

XL rooftop tent. She sleeps on a Therma-Rest Mondo King mattress. I sleep on the built in pad in the RTT.

I'm partial to the Therma-Rest Mondo King.
