Hi Hymie,
Have a 2007 model, it is stored in a building a couple of miles away and I can't remember which way up the mattress is. However, it does not lift as you describe when in use.
Will have a look tomorrow and let you know which way up it is, unless someone else comes along this evening.
Regards,
Mike
