Coleman Single Airbed Extra Durable, Inflatable, Camping Bed, Blue, 198 x 82 x 22 cm, Supports up to 148 kg

I love that this air mattress rolls up into its own wrapper, so when my first air mattress developed an unfixable leak (after MANY years of use), I wanted another. It was difficult to find, and came shipped from another country (I waited a while for that part). But I thought it would be worth it when it got here. When I inflated it, it held air (as expected). However, it was both taller and narrower than the previous version, and a tad bit longer. I use it in a little RV, so the space it needs to fit is fixed. I left it a bit underinflated so it would squish into the space lengthwise, which also gave it a little more space between the mattress and my ceiling. Since it is taller than expected, the underinflation didn't leave me bouncing on the floor. But the narrowness of the sleeping surface was a unnerving. I'm pretty sure I won't roll off in the night, but I'm not 100% confident. So I rolled up a towel and used it as a wedge to keep me on the mattress. It's weird, but I'll get used to it. I can't find similar replacement, so I'll keep this one.
