We do not recommend using this pad for below freezing temperatures.

Question 2

We received a pad that would not stay inflated during its first use.  How may we contact the seller to receive a replacement?

Accepted Answer

I don't know but I certainly don't recommend these. I bought 5 and three leaked. They seem to work if they stay inflated. Another problem is they slide all over the place.

Question 3

How is it for side sleeping?

Accepted Answer

Sleeping pads for backpacking ultimately involve tradeoffs.  Virtually any air mattress in this weight range isn't great for side sleepers, and most of that is due to simple physics: at only 2" thick, you have to inflate the mattress until it's relatively hard if you don't want your hip and shoulder to touch the ground. But it's significantly more comfortable than a closed-cell foam pad or a self-inflating pad (save thick self-inflating pads like the Thermarest CampRest that weigh twice as much and take up 3x as much space in your pack).  I'm 5'8" 160 lbs., and I find that if I inflate my Sleepingo mattress to the point where my hip and shoulder almost touch the ground, it's still reasonably comfortable when sleeping on my side or on my back. (And it's not too narrow, as another commenter suggested; it's actually wider than most ultralight mattresses/pads that usually are 20" wide in the Regular size.)  I have an Exped mattress that is 3" thick, and it's a little more comfortable for side sleeping -- but it weighs a couple of ounces more and it costs 6x as much.  I have a Thermarest Neoair Xlite (not the Xlite NXT released a few months ago, which is thicker and lighter but costs even more), and it's 2.5 inches thick and maybe a little better for side sleeping, but it weighs a couple ounces more, cost me 6x as much, and is 2" narrower...and it's very noisy, while the Sleepingo is practically silent.  If side sleeping comfort is more important to you than saving 4 oz. or so, and you really don't expect to be sleeping on your back much or are even skinnier than I am (so you won't mind the 20" width), you might want to check out the Big Agnes Air Core Ultra, which I haven't used but is 3.5" thick, but it will cost you 2x or more.  But I've been OK with the Sleepingo, sleeping mostly on my side, for several nights in a row.  One other thought: It helps with side-sleeping comfort to have a thin (1/8 or 1/4" closed-cell foam pad underneath at least your torso (which a lot of people do anyway to protect ultralight air mattresses from things that might puncture them), so when your hip or shoulder do bottom-out on the air mattress, they still have a little padding between them and the hard ground.

Question 4

How hard is it to inflate and deflate, looking for quick and easy option

Accepted Answer

How do you inflate this thing? I see people saying 10-20 breaths inflates it. Maybe what we got is different. The valve to blow air into is like an inch in diameter, it's hard to get a seal, I put 10 breaths into it and you couldn't tell I put in a single breath and I'm a runner with good lung capacity. This is ridiculous, trying to figure it out but about to return it.
