As we were making the bed in our Newport we noticed there was an extra 2 1/2 inch loose memory foam under regular mattress. Is this for top of bed if you want a really firm (hard) bed. It may sound like a dumb question but the only dumb question is the one you don't ask. Also our Newport didn't have the remote control for the slides and level up system but I got the instructions on how to set your own code for one. Thanks in advance for any replies.
