How thick is the Serta Mattress?

[wakamicamper]

We are still waiting for our 2010 to be delivered. It is supposed to have the Serta in it as well. Can anyone tell me the depth of the mattress, 8", 7" or something else. DW wants to know what size sheet set is required on the mattress. At home our mattress has a pillow top and is 14" deep. So we can't just take some from the house.
The heat setting is it for just the electric, or does it also work on 12 volt?
Thanks

The heated mattress option, if that is what your'e asking about, plugs in to a 110v plug on the wall, so no, it is not 12 volt. lso, the mattress on mine isn't very thick, but we put pillowtops toppers on there, and we love it now! However, the mattress is 6" shorter than a home mattress, at least on our unit. Randy

Thanks for the reply. We are waiting (impatiently) for the trailer to be delivered to the dealer. We have been told sometime late March, early April 2010.
