Air beds

I recently travelled to a place called Mumbai in India. I took a flight from Spain and reached New Delhi which is the capital of India. I then reached Mumbai through train. During my train journey to Mumbai I was able to know about the country and people a lot. I knew that travelling from New Delhi to Mumbai will take at least 2-3 days and so I had an air mattress with me. The air mattress helped a lot and it made me comfortable during the night time. I feel that air mattress is one of the essential things to have when you are travelling or camping. Along with air mattress, Air beds are also doing well in the markets. Compared to air mattress, air bed are quite elaborate. Air beds can be used as guest beds or can be used temporarily. I guess in future we will be fortunate to see large variety of air beds.
