Loved this pad, but now it needs repair and crickets. . .

This has been my favorite sleeping pad hands down, but has since delaminated. I took pictures and sent in the warranty request over a month ago and nothing. I guess a lifetime warrantly is easy when you don't have to honor it, right? I loved supporting a US company but now onto other brands. Even if you call their number to talk to someone it just directs to the website. Sad.

Man’s best friend

For any father that has experienced the dad couch/chair in the hospital this mattress is the bees knees and the ducks guts. It turns what I can only explain as an attempt to put the father in as much pain and agony as his wife into a soft delicate cloud bed. This fit perfectly on the dad chair and was complimented by all. Additionally this mattress has performed extremely well camping. Fathers to be this is a neccesity.

How to keep this short... I'm 72. Started back-pack camping in 1966. There were no back-pack camping mattresses, and if there were camping pads, I never saw one. In the early eighty's, as a"die hard" San Francisco bicyclist-skateboarder (Three spinal surgeries: w/ metal rod in 1976, then broke the rod and replaced it with a hip bone graft in 1986) I became passionate about snowboarding. Simply put: I discovered Thermarest sleeping pads and was able to go anywhere someone would let me lie down for the night, and get a good night's rest, then get up and go snowboarding. As a result, I became well employed in the industry. Now, I live on a boat, where I sleep on the Thermarest Mondo King over the standard foam mattress. (The bedside lockers won't open if blocked by a thicker mattress.) So, 40 years with Thermarest. Great memories, and a good back... HAPPY CUSTOMER!

Awesome!

The best pad out there. The quality is top notch, I didn't even notice a comfort difference between this and my mattress at home. The initial cost is up the investment is worth it!

Cheaper, buy the Large model!!!

Pretty cheap compared to the large version... Feels like Thermarest took it 10 years back.. This one has no anti return on the inflation valve, so always deflating when unplugging the pump. Wouldn't have bought it if I knew. Can't return it because it is not a default.. they make them like that, they just don't mention it to clients. As far as comfort goes it's the same, just wider.

Most comfortable camp sleep ever!

Used my new Mondo King on a 2-week fire assignment in Oregon. Got some of the most comfortable sleep I ever had while working fire. Bulky to pack, but worth it to sleep soundly. Pad inflates fast, kept air through 60-degree temperature swings, and over a two week trip with no losses.

Great Pad

Familiarity:
I've used it several times
Size Bought:
Xxl
Height:

Weight:

My wife and I purchased 2 of these for backcountry sleeping. We are packing in on horses so weight isn’t as much of a concern when it comes to sleeping. We have them inside of our bedrolls and we both love them. I have spent about 12 days sleeping on it now and I have no complaints. You can have it as soft or firm as you’d like with the air pressure. I run it a little more on the soft side and it is comparable to my purple mattress at home. I have not slept this good in a very long time while camping. The pad rolls up smaller than you’d imagine due to the comfort that it provides. My wife has also slept great on it. She has not slept very good in the past as other pads hurt her hips. We looked at Exped pads and would say this is every bit as comfortable perhaps a little better in my opinion. My uncle runs an Exped, he has a few fused vertebrae’s and he says the Mondoking is fantastic for him. I have no complaints about this pad it’s comfy, you’ll stay warm and sleep all night. If you’ve got the space or the desire to carry a little more weight with you, don’t hesitate, just buy it. I’m looking forward to many more nights this year on this pad.

Changed design disappointing.

I gave this bag a full five-star review. I used it for many years, and it just needed replaced. So I bought another one. Previous design had a smooth surface. New design has ridges on the surface, and I can feel them, so I need a pad for the pad. Doesn’t make sense. Why the change? It wasn’t for loyal users. Poor redesign. I am disappointed with the change from a wonderful pad to new design.
