Query: Last time I am buying a Coleman air bed

The price may be low, but you get what you pay for. This air bed is a pain to pump, which is sold separately. The pump is also huge so taking it camping means another thing to transport and carry. This airbed doesn't have a leak, but it always seems to sag to the ground when I wake up. I would get back and neck pains sleeping on this thing. After a few uses, I decided to throw it in the trash. I am going to look for a higher end air bed with an integrated pump! Don't buy this bed if you want a decent air bed for long term.
