I have a hardly used Temperpedic twin extra long bed. Original price was around 5K, was used in a guest room that hasn't been used for 3 years, here are all the features
Head and feet elevate
Massage head and feet
Lighted under bed as night light
Has zero gravity button where head feet move to a set position
On floor is extra riser to raise bed higher off floor
Always had a bed cover
Has the cool feature that says it helps lower body temperature by 10 degrees
