MegaMat Series
Car camping comfort champ, but some side sleepers find it thin.

Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Similarly, Nemo Roamer double. Both are great and are super comfortable. Saw the Nemo Roamer double on sale recently too.
REI or Nemo (or exped, but imo either get the REI for less or the Nemo if packed size is important to you). I’m talking about their self inflating foam and air mattress in the two person size. And get a backpacking quilt from feathered friends.
I have been extremely happy with the Nemo Roamer, which looks similar to the MegaMat. https://www.nemoequipment.com/products/roamer
The Roamer has very big vents and is not hard to fully deflate.
Same, I love my Roamer. They have provisions on the sides to attach two mats together.
I’ve been sleeping full time on a Roamer Double for 3 years now, it’s the most comfortable mattress I’ve ever had. It’s like new. No puncture or damage, even with the cat.
Nemo Roamer Double - best I've ever experienced and I work in the outdoor industry.
