Blow up bed (Chelmsford CM1)

I'm looking for a blow up bed to take to my daughters with me. I have a bad back and slept on a mattress on the floor which was ok until I needed to get up for the loo, I looked like an upturned tortoise and could not get up for love nor money. I woke the whole household & probably next door 3 times in 1 night oooops!
