The exped megamat duo is almost as comfortable as my bed at home. As I’m getting older, that makes a huge difference.
I don't know where you live but where I live those double sleeping bags let too much heat out and both people are miserable in the middle of the night. We have a double size exped (https://www.rei.com/product/238244/exped-megamat-duo-sleeping-pad) with individual sleeping bags. I also highly recommend a pillow: https://www.rumpl.com/collections/pillows-and-pillowcases I have an extra puffy blanket to layer over my sleeping bag and to use around the campfire. We have a 6 person tent for the two of us - my husband wanted one where he could stand up straight. We each have a headlamp and a solar lantern: https://www.rei.com/product/248291/biolite-luci-original-clear-20-inflatable-solar-lantern Bring sandals for late night bathroom trips. We use a picnic blanket as a rug of sorts as well.
We just did this and have 4 kids. Some items like a Coleman stove we already had, but here’s what we bought to get started. It adds up but was still so much less than the AirBnb even after campsite fees. We mostly camp in New England hence the sleeping bag choice. Good luck! 1 x NF Wawoma 8 Tent w/ footprint tarp 6 x NF Wawoma 20 Sleeping Bags 4 x Nemo Switchback Sleeping Pads 1 x Exped Queen Megmat
This. Went back and forth for a year and finally got one. It’s been great.
Same. Originally bought some cheaper solutions until we ultimately went w/ Exped. Spent 6 great nights in Maine in September and it was amazing. Buy once, cry once :-)
Just bought one two weeks ago. Couldn’t believe how small it is. Works well!
This. I went the Nemo route to save a few $. Went back and forth and finally bought the Exped. Absolutely worth it. I sleep better on it than my mattress at home.
Exped MegaMat Duo 10 M
We bought 2 x Duo LW+ for camping with 2 kids. Absolutely the best investment we've done in the sleeping system (tried cots, various pads, etc). Definitely not anywhere close to a budget option, but if you have the funds - well worth it. If you want to mimic home mattress scenario - go with duo. Edit: kids are still young so we co-sleep, hence, the choice.
All depends on your tent dimensions and the position you wanna fit. Honestly, what I have provides ample space and comfort. I wouldn't change it. The only caveat, you might change tents down the road (what happened to me, not by choice) and took me awhile to find the alternative to have the same setup. Good luck.
Exped Megamat Duo LW is the best, we also have a double sleeping bag from REI - Siesta Hooded 20, after using a cheap double one from Amazon for 5 or so trips. The upgrade was great. But we love to snuggle, I would hate it in a single sleeping bag :) as for the tent size, we actually downsized from 6P to 4P tent, as 6P was too big even for the three of us (a couple with a young kid). I don’t really need to be able to stand in a tent - we barely spend any time there.
Love my exped megamat, but I’ve only had it for a few months and seven camping trips; here is a YouTube dude who has the best gear game, he just reviewed his megamat after five years: https://youtu.be/VGQWuctCxks?si=SS4kgTz\_E0W-FeYX
