It/they fit inside the king size bed we had been using so it was a quick and easy conversion.
I'm using a Purple 3 mattress and I love it. Wife has a more conventional pillow-top.
This has made an amazing improvement in my/our comfort level. I started with the preprogrammed "zero gravity" position and then increased the angle of the back (to about 40 degrees) and then saved that position to a programmable button in the wireless remote. Wife uses a much less aggressive position.
I now sleep 100% on my back. Prior, due to long term OSA, I would roll over onto my stomach wreaking all manner of havoc with my lower spine, neck, and GERD.. (turning the head tightens the tissues reducing OAS)
Due to the angle of the back I now have a very low AHI (0.4) and GERD is much reduced. My lower spine is much happier also.
It has an under bed lighting system which is only used when vacuuming but it does make a nice nightlight should the need arise.
Has vibrator motors which I originally saw as a gimmick but now we use them almost every night. The vibrators really do sooth on difficult nights.
Has USB charging ports but IMHO bed is for two things and electronics is not one of them.
IF I had it to do over I would have spent the extra money for a version with the adjustable head tilt section AND the wall hugger feature. We don't have the head tilt so I must find a pillow that supports my neck against my Hashimoto's and without the wall hugger and with the back tilted up it is difficult to reach my side table.
We love our adjustable beds and we are both using CPAP. The models with all the toys and whistles is double what we paid but in retrospect I wish I had gone ahead and spent the money. Should finance ever permit I will replace with the upgraded model and move our current bed to a guest room.
Of course any guests may never leave
