We just got a Tempur-Pedic bed, with 8 USB ports!
Also adjustable and vibrates etc etc.
I raise the head of my bed a bit to reduce reflux. I sleep on my side. When using the bed to relax and read the head’s elevated more. I don’t elevate the foot often, if at all. The Mrs. does, to help her swollen knee.
USB ports are handy for recharging kindles, iPads, etc. But we haven’t enabled the wireless to it, so it doesn’t record/report our sleeping (or other bed) habits. Nor do we employ dildonics. We’re more old school than that. I doubt any of our gear has a USB port.
It was very expensive, over $10K for a king sized with most of the trimmings, frame, etc. But we anticipate using it as a hospital bed after the Mrs. has her knees replaced, and the extra stuff will come in handy then.
We both sleep better on this thing. We went for an extra firm mattress instead of our usual medium one (which we’d used for 22+ years) because we’d been in an AirBnB with a super firm mattress, thought we’d have terrible nights trying to sleep on it, and wound up sleeping and feeling better than ever on it.
Haven’t stayed anyplace away overnight since we got it tho.
