My wife and I have a I-Series Intelligent Comfort/Individual Support King Size Pillowtop mattress with a split King size foundation with adjustable head and feet positions as well as massage features for both the head and feet.It comes with a lighted remote to  operate the functions...This bed was purchased 2 yrs ago for our guest bedroom and has had very minimal use.We are in the process of moving here in the next month and will not have room for this size of setup at our new place...This unit is in EXCELLENT CONDITION!!!.... We purchased this setup for 6500.00 2yrs ago at Mattress Hub.Thanks,Bob
