We have a queen size "stretcher' type bed which has a concertina type base. The mattress is inflatable but then fits into a cover type arrangement which is attached to the base. The whole kit comes with an air pump and is transportable in a bag on wheels. The bed has done duty at various locations when people needed an extra bed for guests, camping etc and so far (since 2005) has stood the test of time. It is also very comfortable and doesn't feel like an airbed.
Next year we will be taking it on an extended trip as we have two friends sharing the c/t with us.
Sorry no pics at this stage but I know these things are still on the market.
