DeepSleep

Exped is one of the most popular (for good reason) and on sale at REI currently. We have a Megamat duo mat that is amazingly comfortable. I also have a deep sleep mat for solo. Def bigger/heavier than basic inflatable but 100% worth it for the comfort. They make several different thicknesses depending on what you'd like but even the thinner mats are extremely comfortable and warm.

Yea I think that's their entry level self inflating mat. Thinner than the others but still warm. I got it to go with my zenbivy and it is great! You do still need to inflate it yourself but I definitely recommend practicing getting the pressure right. You don't want it so high that you're sleeping on a board, but so low that you sag too much into the pad. It does take a bit to get used to the way it feels when you have it just right. I'd probably recommend putting some silicone dabs down on your cot so that it won't slip/slide, or use some kinda of silicon tape for the same reason.

I am the OPs size and the Expeds do very well. I have several, a shared Exped Megamat Duo, Solo Deep Sleep, and a Dura 8. All perform well and are very warm even in the cold. I've taken some down to 20°F (-6°C) and was fine.

Exped is considered one of the best, there are offbrand versions as well. I would probably go for a 3 to 4 inch self inflating foam pad. Still need to inflate it yourself some, but you can adjust it to be both supportive but comfortable. I use an Exped DeepSleep when camping and it does the trick. My SO has the MegaMat and it’s also extremely comfortable. I feel the brand is worth it IMO for ease of warranty vs generic brands, but depending on your cost or warranty options in your country that may change the equation. Shorter pads can be ok if you have a big enough pillow or don’t mind your feet off the end (I don’t terribly) Personally I’d probably spring for the Exped and call it a day. They can be found on sale pretty regularly but that may not accommodate your timeframe. Easier just dealing with the 1 pad vs 2.

Any Exped Med-Wide pads fit the bill. Incredibly comfy to boot. They are more expensive but a good nights sleep it worth it imo. Best investment I made for camping. I got my Deep Sleep for just over $100 on sale.

Indeed. Throw it on a cot and it’s almost better than my bed at home 100%

Exped Deepsleep self inflating pad + Zenbivy system. So comfy! If you need a cot to get higher off the ground to make getting in/out easier then any one that matches of size should work. I’m partial to Coleman Trailhead 2 but most are the same, just make sure of weight capacity if you’re a fluffy boi like me.

The rule I've always heard is 1R for every 10 degrees below 70 as a \*minimum\* for survival, similar to how a sleeping bag rated at 0 means you'll be comfortable-ish around 10-20. Following this you'd be looking at a R5-6 at 15-50 so you're right on the edge of that. Applying the same 'comfort' rule you'd want a 6-8 depending on if you like sleeping cooler (6-7) or warmer (7-8) Exped Dura 8 (or DeepSleep \[R9\] if car camping) would be a strong contender for me in those temps. My philosophy is you can always vent heat if you're too hot in the cold, but if you're cold in the cold, you're cold.

The thing is built like a frikken tank, and I love it. Sure I could go lighter with the Ultra but I just love how strong the Dura line feels. I also have the DeepSleep for car camping and it's in the same vein. Very comfortable both, but I do love the added cushion in the foam mats.

Exped is good, several models depending on what kind of camping. For reference I’m 6’ 330lbs. MegaMat/DeepSleep used for car camping. Dura used for backpacking. You may also be able to use furniture foam which would be cheaper and can be cut to different sizes.

Check if you actually need the LXW, or regular wide is enough. The LXW is quite large, which has merits, but unless the sleeper is 6'+ or indeed quite wide, it is excessive. Also, make sure your tent has room for a ton of Megamats before you commit to buying a lot of Megamats. Maybe start with one for your wife and see how it goes. They tend to take up a lot more space than one would think. Also, Megamat Deepsleep is a bit cheaper than the 10. Depending on the needs, that model can be enough (it is still quite cushy, has all the same core / support).

Self inflating sleep mat. ExPed Deep Sleep 7.5. Very comfy. I was once camping on rocky lumpy ground with a friend whose inflatable pad was leaking air. She went to sleep in the car. I put her half inflated air pad under my own pad. Best camp sleep I’ve ever had. Now when I car camp and I expect the ground to be exceptionally lumpy, I bring along an air pad that I partially inflate to go under my ExPed. It works perfectly every time. The ExPed works perfectly on its own when the ground is reasonably flat.

I like my Exped Deep Sleep 7.5.

Self inflating foam + air. ExPed Deep Sleep 7.5. It doesn’t feel like an air mattress.

I use the Exped Deep Sleep 7.5 with happy results.

Which Expeds are you talking about? I ask because their backpacking ones are about the same weight as competitors. But the Megamat and Deepsleep are not for backpacking, but massively more comfortable, obviously.

Something to consider is that the deepsleep is 1”/2.5cm thinner, but it’s ironically warmer.  Exped had to core out the foam of the megamat to keep it a reasonable size/weight/maintain packability.  The deepsleep is a solid piece of foam, so it’s warmer.  It’s already a bit thinner, so it doesn’t have to sacrifice anything for size/weight/packability.

For comfy camping (not backpacking) my husband and I have our own exped deepsleep 7.5 pads and keep them bound together with a very thick mattress topper. We also bring our own real pillows and either blankets or sleeping bags (depending on the temps). We originally tried sharing an air mattress, but he's about 80 pounds heavier than me, and every time he shifted, I was jostled all over the place. We also tried to use our backpacking pillows, but that just wasn't feasible. Our sleep setup does take up a lot of room when packing, but it's honestly worth it so we can both be well rested and have the best time camping.
