Sleep Number & Other Air Mattresses
What Sleep Number didn't tell us.
After replacing two bladders (at different times) in our queen size air bed, my spouse has become the "Pressure Checker". Our losses were aggravated by crossing the Rockies twice. Yes, air pressure decreases with elevation, which increases the pressure in the air bladders. They don't collapse -- just start leaking a little. And one morning you awaken surrounded by softened mattress.
Air bladder pressure changes with outside temperature as well. If located over a hot engine you can be sure the pressure will increase substantially. Likewise, cold outside air will deflate somewhat.
What to do? Deflate by half before hitting the road. Then reinflate before bed. When changing climates, adjust air pressure for your comfort level.
Here's to more comfortable sleep!
