This mattress has been upgraded for camping, but it also works wonderfully as a guest bed at home. Inflating it is quick and effortless, while deflating and packing it away is even faster. It holds air well, and softening the mattress (by releasing some air) is easy whenever needed.

It’s a good product, and I’d guess it’s more comfortable than Tesla’s own mattress since it’s thicker. When packed, it fits easily into the sub-trunk, leaving enough room for sunshades as well. In addition to the mattress, it’s worth getting some kind of support for the head end, as it otherwise sags over the open space. Of course, this is an issue with all mattresses used in Teslas. If I had to find a fault, the mattress could perhaps be a tad thicker for added comfort. Also, deflating and packing it up is a bit slow since an electric pump isn't included. Fortunately, that doesn't really bother me, and there's no huge rush anyway :)

After a few nights of use, it’s easy to say that it’s great! The mattress offers bed-like comfort and feels high-quality. I recommend pairing it with a battery-powered pump, such as the Exped Mega Pump; it makes inflation and deflation easier and faster compared to the hand pump included with the mattress.

The first and so far the only "camping mattress" that my back can handle. I've had it for several nights now, and I haven't regretted the purchase once. A quality product in every way, although it is expensive, I think it is definitely worth the price.

We’ve been really impressed with this sleeping mat. It holds air perfectly—no deflation overnight, even after multiple uses. For the best experience, I highly recommend purchasing the Exped pump; it’s the perfect match and makes both inflation and deflation quick and effortless. As for comfort, this is by far the most comfortable sleeping mat we’ve tried. It provides great support and insulation, making for a restful night’s sleep wherever you are.

Good durability, not easy to make holes in it, size suitable for Tesla Model Y, but perhaps the biggest challenge is the slow self-inflating - you always have to use the hand pump up to 50 times or more to get it inflated. In contrast, the presentation video said that when spread out and the IN valves open, the mattress should self-inflate about half way - this did not happen.
Rolling, deflating is a bit challenging, but I have no point of comparison how it works in other models, so maybe that's ok too.
But the most important feature - the sleeping comfort is absolutely top notch, neither of us has back pain (we are a 50-year-old couple), there was something to choose from on the air mattress every morning.
Yes, this Exped Megamat Auto mattress is a purchase worth its money.

A firm mattress, good to sleep on even as a guest mattress. The Ioniq5 fits comfortably in the back. Folding it up requires some skill.
