Question: So this beed does not need any type of air pump, correct
Document: Huge ... airing down manually is slow and tedious (minus a star). A deflate pump will be welcome if you buy one of these,Bought it for use with my Tent Cot. It fits inside, leaves room at an end for shoes, phones, whatever. It can be rolled up on the cot, but you really need to lay into the rolling and I worry about damaging the cot pressing so hard.
Pros:  1.) Nice, comfortable, self-inflating pad, that appears to be well built and durable for it's category. 2.) Self inflation, even when car camping or base camping is sometimes preferable to a mattresses requiring an air pump to inflate. 3.) Rolls tighter than a similar thickness closed cell foam pad will. 4.)
Expect 12&#34; to 14&#34; rolled without a pump.
The thing is, even though I noticed it was lower than when I went to sleep, it didn't wake me up. Plus, I wasn't positive it was truly low on air, I only suspected it. Had this been a regular air mattress there would have been no wondering if it was low.I have tried the very thin self inflating matts in the past. Those are so thin that when they lose air there is too little foam between you and the ground to make any difference.
I purchased this matress for car camping with my son. I was looking for a big thick matress because I am a big guy. The foam in this matress is very soft but is not attached to the inside of the skin as it is with some of the thinner matresses (thermarest). If you try to add more air to it, you get a balooning effect, however extra air is not as improtant with this matress due to its thickness. I was surprised with how well it rolled up.
Over the years I have tried many air mattresses. None have worked out for me. No matter what, they always go flat! With these I figured that with the open felled foam interior even if they did go flat you wouldn't be laying directly on the hard ground. It turns out, these worked exactly as anticipated. We used these to camp for a couple of days and on the second day when I woke up I thought that the mattress seemed a little flatter than when I went to sleep.
This pad is wonderful! Went camping (tent and in my 60's) for a week and slept like a baby. So easy to inflate, Great roomy carrying case and lite to carry. Do need someone with larger hands (I have small hands) to roll it back up. I could do it but it would take some time. I tried another brand (C_ _ _ _ _) and it didn't even come close to quality.To say the least I AM VERY HAPPY!
where rolled size is not a big issue, I find a closed cell foam pad to be as comfortable to sleep on, more comfortable to sit on, comes without the worries of puncture and will likely have a much longer life-span.For situations where one will not be carrying a pad (backpacking, etc. ), where a twin inflatable mattress is too wide, and where a closed cell mattress is to bulky, this pad may be a good choice.
Used this for 2 weeks straight on my cot at boy scout camp and it's the only thing that kept me sane. Thick enough that my limbs didn't fall asleep as I lay on my side. Worth every penny!
Light wieght easily puntured ok for some uses I suppose, but won't last long! I won't buy another one. Sorry
