MegaMat Auto

Exped mattress with r value of 8. Best $500 we've spent for car camping.

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 no experience with Lost Horizon, but I do have the Exped Megamat and in my opinion I would buy it again and the cost is well worth it. I’m a side sleeper and the thick padding + added air is a game changer. It’s also very insulating and warm during the colder months. I got it during REI’s Labor Day sale last year.

I have the 4” and I weigh more than you and do not bottom out on it

I would get the 4" thick Exped. I have 6" and 4" and prefer the 4" because both are very comfortable but 4" packs 30% smaller.

For car camping, check out Exped. My wife and i each have the wider/longer 4" model, and together they add up to a queen size. We put a fitted sheet over them which holds them together, and it folds up. They are also easy to pack and can also be deployed separately. It is much more convenient that one huge double/queen.

Not sure what your mid-range cost is but I absolutely LOVE our double exped mattress. I honestly sleep more soundly on that thing than my own bed its so comfortable. We also have a 6 person tent (can't remember the brand) and find that its great to sleep both my partner, me and our dog with a good amount of extra room.

I have a double size Exped, and it is just too big for us to pack up for car camping. I went with sleeping pads so I could actually fit it in my car. I love the idea of cots, but I don’t know how people put them inside cars!
