Blow up Bed

[manorline]

Hi what is the best blow up bed. It can be big and heavy as i want it for home use mainly. (and camping sometimes). I have bought a few over the years and they all deflate half way through the night

Many campers these days use self inflating mattresses (SIMs) which have a foam core, supplemented by trapped air.

You can get blow ups that have a constant electric pump running to keep them inflated.

Blow ups will all deflate slightly when the temperature drops at night.
