Just picked up my Cybertruck last week and honestly the vault is way trickier to outfit than I thought. I looked at that official air mattress from Tesla but people on the forums keep saying it leaks air like crazy and for 300 bucks thats just not gonna cut it for me. I also saw some DIY foam builds on YouTube but I really dont have the time to cut upholstery or whatever right now since Im heading out to Joshua Tree in two weeks. My budget is like 400 max but I just need something comfy that actually fits the weird geometry back there without sliding around. Does anyone have a setup that doesnt suck?

Adding my two cents here because I spent way too long dealing with the vault geometry during a desert trip last year. Before you drop any cash, are you planning on using a power station to inflate something, or do you need a self-inflating option that works without any extra gear? Being stuck in the middle of nowhere without a pump is a total nightmare, trust me. Since you are going to Joshua Tree soon, make sure to pack some extra padding for the wheel wells because they can be super unforgiving. I would suggest checking out the Luno Life Tesla Air Mattress if you want a perfect fit without the DIY headache. It is a bit pricey, but you might want to consider it over the official one since it actually stays put. Just be careful with sharp gear near the sides, though.

Honestly, grab the Therm-a-Rest MondoKing 3D Large or Hest Sleep System Wide. Both are way more reliable than those cheap air mattresses and won't leave you stranded in the desert.

Congrats on the new truck! Honestly, skip the Tesla one. I've tried many over the years and those official air mattresses are usually way too thin. If you want something that actually fits the vault geometry without sliding, just grab the Exped MegaMat Auto, specifically the one designed for EVs. It is miles ahead of everything else in comfort and the self-inflating foam is a game changer for setup time. Since you are headed to Joshua Tree soon, you dont want to be dealing with leaks in the desert. Just throw that in the back and it basically contours to the floor perfectly. Its definitely worth the extra spend over a DIY mess and youll be sleeping like a baby. Stay away from the cheap stuff, trust me.

Saw this earlier but just now getting around to replying. Honestly, outfitting the vault is a total nightmare because of those angles. I spent a weekend out at Big Bear a few months ago trying to make a standard camping pad work and it was a disaster. The wheel wells basically forced my sleeping bag into the center and I felt like I was gonna slide out all night long. I honestly stopped trusting the big branded air stuff after a few punctures out in the desert. In my experience, if you are heading to Joshua Tree soon, you really want something with a bit more structure than just trapped air. I heard some folks on another board talking about high-density tri-fold toppers. They dont slide around half as much because of the weight, and you can just fold them up when you need the space for gear. Here is what I noticed helps with the geometry:
- Look for toppers that have a non-slip backing, its a game changer when the truck is on even a slight incline
- Dont go for anything too thick or you will be hitting your head on the tonneau cover constantly
- Bringing a few extra furniture pads to level out the floor near the tailgate makes a huge difference Im not sure if they make a custom fit for the CT yet, but a local upholstery shop once cut a piece of memory foam for me in a few hours for way cheaper than retail. Might be worth checking if you have a place nearby.
