Great purchase, very glad I

Great purchase, very glad I spent the money. Very comfortable, packs much better than I anticipated and you can make it as firm as you need it or leave a little air out for a softer feel. It also is very easy to inflate.

Perfect for Car camping!

Excellent car camping pad. Self inflates most of the way, minimal noise while sleeping and moving around, and rolls up nicely.

Mondo king = Beyond comfy

If you are in search of an air mattress that puts your at home bed to shame, look no further. This is the gold standard of glamping mattresses.

Leaky Valves? No One to Talk To.

These Mondo Kings seem to lose a bit of air, over a few nights, unlike our previous but thinner Therm-A-Rest pads, that we'd been sleeping on for the past six months. Those took weeks before they needed the inflation tweaked. We don't know if these new Mondo Kong valves are faulty, or this is normal for this to happen with them, and I really dislike the fact you can't just call up Cascade and talk with someone about it. So we don't know whether they're defective, or this is normal or not. We use these pads as our everyday mattresses, side by side on our queen bed platform, because having individual pads enables us to adjust the firmness to our different needs. I don't think we're stressing the pads- she weighs 107 lbs, I weigh 129. It would be nice to be able to actually talk with someone about what may or may not be going on with these new Mondo Kings, but Cascade doesn't want you to actually talk with another human being. It may be a cheaper system for them, but it diminishes any allegiance and trust we'd been feeling for Therm-a-Rest, based out our previous great experience with our prior pads.

Comfy

This is way more comfortable than your average camping mat. My only regret is not getting the wider width. It is plenty wide enough for one person, but I roll around a lot. Once you find out just how much air to put in for your personal preference, it’s perfect. The storage bag that also inflates the mattress is so handy.

The Cadillac of sleeping pads

A bit big and bulky, but it's great for summers when my husband and son sleep in a tent in the backyard. We've yet to take it camping but so far they are more comfortable than the air mattress we were using.
