Hi LOGANROSS,
Most adjustable beds (including the Leggett & Platt models) have a solid surface.
A solid surface support system that doesn’t provide any ventilation underneath the mattress can add somewhat to the risk of moisture retention and developing mold or mildew in the mattress but if you don’t have any additional risk factors in your environment then it should be fine (see post #10 here). I (and many others) use an adjustable bed with a solid surface under my own latex mattress with no problem.
Congratulations on your new mattress as well 
You certainly made a great quality/value choice and I’m looking forward to your comments and feedback when you receive it and have had a chance to sleep on it for a bit.
