Altitude effect on bed and other things

We recently got a select comfort bed. We saw some posts about the effect of altitude on the pressure inside the mattress. In one case they said the setting went from 45 to 90... that seems extreme to me. Also, someone else said they had a carton of milk explode in the refrigerator. We have been at altitude (7000 - 8000 feet) without any obvious consequences... but that was before the air bed.

I'm wondering what other people have experienced with their air bed when they increased their altitude... also, any other things that were affected.

I spend months at 9700ft and then back to 192ft. Sure you air bed will change, no big deal - just re-adjust. The potato chip and salad bags at the grocery store will be fully inflated too - at least you know they are sealed! They are kind of funny looking that way. No problems with the gas-absorption refer or any other RV appliance. The only advice I'd give is to enjoy your time in the mountains and use an ice pick to poke a small hole at the top of ALL your soap/lotion bottles with a pump top to allow them to breath w/o forcing the contents to drip through the spout as you change altitudes.

Your Select Comfort will ABSOLUTELY inflate going up in altitude. We normall keep ours at 35 and the first time we went "up", we went from 3,200' to over 7,000'. Our mattresses were hard as rocks! The other stories you have heard about the effects of altitude are most probably also true as we have had most all of it happen to us. Now we just anticipate and plan ahead.

Please make sure you deflate the bed before traveling. You may be going someplace that is not that high...but you may be traveling over mountains to get there!
We had our bed expand quite a bit going up to only a 3000 foot elevation. That made me a believer after that.

Wow

We have a sleepnumber mattress ... a few years ago we were camped next to the ocean in Winchester Bay, OR ... our mattresses were inflated at about 50 to 60 at the coasts ...

We drove from Winchester Bay to Crater Lake which is about 6000 feet elevation. When we arrived the mattress was hard as a rock ... I felt lucky that it did not suffer any damage ...

We now deflate to about 25 whenever we think we will gain 3000 feet of elevation in a day ...

I know this has nothing to do with air mattress's but I would like to say my 2Ę about expansion and contraction. I worked at a Plate Glass factory for a few years and we made double pane windows for a year or 2 and when they put them together they put a small vent tube between the 2 plates so as to when they went over mountain ranges the pressure would equalize and not ruin the seal. Once they got to their destination they would pinch off the tube. Not sure if they put Nitrogen in or not before pinching off the tube.
I am wondering if that is the cause of all the Se-Gi windows having their problems. I know my windows look like heck with the seal snaking all around. No fogging yet thank heaven.

I will add one more thing, do not pack your chip bags tight together because they will blow out the top if they don't have room to expand.
