"Side sleeper. I use Exped. This is the main reason I haven't tried a Thermarest or Rab pad yet, no lengthways baffles. I love them and they can really help you stay on the pad if the ground is all over the place."
"I'm heavier and shorter than you and side sleep on Exped mats just fine."

"Over time, the Exped began to leak ... As best I can tell, the rubber lining inside the fabric begins to slowly degrade and develop pinhole leaks. ... You never hear leaking air. You just wake up in the morning with your hip touching the ground (I’m a side sleeper)."

"on Exped pads, DO NOT simply pull the flap to open the valve. BE SURE to hold the part of the valve that is permanently attached to the pad fabric separately so that the forces of opening the flap do not tear the valve out of the fabric."

https://www.bever.nl/p/exped-sim-3-8-m-MBBCC70028.html?colour=1594 Ik heb je budget een beetje ingeschat. Een exped megamat is de grote broer hiervan en die gaan lang mee bij normaal gebruik en heel comfortabel. Worden vaak als best buy geboemd. Dit is wat kleiner compacter, dunner, maar ook reisbaarder. Hiken, backpacken, weekendje weg. 3 weken camperen zou ik toch voor wat duurder comfortabeler gaan wat meer op een matras lijkt ipv een camping matje.
I've had four Expeds. Still have two. Both have the built-in pump. One has synthetic fill. The other has some down insulation which makes it good for ~10F colder than without. The first two developed tiny leaks (could not find them even with submerging). They were a few years out of warranty. Exped still replaced both. I appreciate a company that stands behind their products. I also like side-sleeping. I have not used these as much as what you will. So durability...🤷
I was using a backpacking style exped inflatable pad and recently replaced it with a self inflating one. Takes up a lot more space but far more comfortable (and quiet!).
I have an exped pad for backpacking and I love it. Most comfortable one I’ve ever used
Exped is the current king of the semi self inflating mattresses but there are other worthy considerations which are more affordable, especially on sale. I went with a Lost Horizon I found on clearance for half price. Probably not as bomb proof as the Exped, but after about a dozen trips this summer it’s going strong without issues. The bottom line is these type of mattresses are exponentially more comfortable than anything else on the market. I will never go back. The only drawback is they don’t roll up small.
I can't remember if ours is an exped or not, but it's a double size one for my wife and I. I remember kind of cringing at the price initially, I think I paid double what our sleeping bag cost. Total game changer. We sleep so comfortably, even in 30 F temperatures.
I have an Exped. Not loud. And of them can make some noise sliding about on say tent floors, depending on the relative texture etc of the fabrics. Not way to know for sure until you try it. Or, more easily, just use something between them if it's an issue.
I've had great success with Thermarest, REI, and Exped self inflating mattresses. All have good customer support too. I wouldn't ever bother with an all air mattress. Poor insulation, rotten in cold. Get a FlexTail pump.
I tried long term sleeping on an Exped. They're a seif inflating pad. It did not last a full year. The fabric in those is glued to the foam, and as it turns out tossing and turning can eventually break that bond, and the fabric blister.
Yes. They were going to honor the warranty, but it was less than a year so just easier to drop it at REI where I bought it and get a refund. Definite bummer; great mattress even at home. If they ever do a long lasting home version I'll be all over it...literally. :)
I'd say Exped but the "self-inflate" part is a lie. Otherwise they're the best
You are off to a great start and almost anything you need is gonna just depend on your activity. It doesn’t look like you have a sleeping pad. I would highly recommend a thick self inflating type, like an exped, if you are car camping. If you are interested in backpacking, you could get a more compact style, but I find the self inflators pretty bombproof and very comfortable. I sleep better in my hammock than I do at home, but that is gonna require a tarp, hammock, and under quilt; all of which can be pretty expensive.
xped makes a great pad/mattress, it's kind of a cross between the two, mine has lasted for years
love my xped for car camping. kind of a cross between the two
if it helps i think i'm on year 5 with it.
