How could they miss this? I'll never buy a Model 3 now. A Twin mattress is 39 inches wide, and they designed the car to be an inch too narrow at 38 inches wide. They hate us car campers!
Anyway, almost any twin sized mattress (blow up, or normal innerspring) should fit in that 38 inches without much complaint. You'd never get a hard-frame box spring in there, but I doubt you'd find that usable even if it did fit.
Heh, it looks like the cheap inflatable mattresses cut off an inch to save costs, and are already 38 inches wide:
Yes, I'm 6 foot and I was thinking this should fit just about right and be comfortable to sleep on. Not sure if it is going to hang over a bit with the rear seats folded down but maybe you could let me know if you go with it. Or if you find a better solution please post....with pics! Congrats on the car by the way, we are all a bit JELLY!!
Okay, so Amazon list the length of that mattress as 78". In the video by Trev and Kenneth the measured the back with the seats down at 66". So, it will hang over but maybe it could be supported or maybe just use the two larger sections and the two smaller sections will fold into the foot-well area. Either way I think it's the best option for now....unless someone else finds something better. For those of you getting the car please let us know if you find a good solution.
I considered that, but decided to splurge a bit and get something that I can roll up and this thing is super comfortable. Plus it was $50 off when I ordered it. I plan to use it quite a bit during the summer at my weekend job so being comfortable is worth it.
I ended up going with the one that was exactly 38", the highest stars available, and with no pump to keep the weight down. If it turns out to be a POS, it's $18 and goes in the garbage. I'll post pics when I get it set-up.
