Split king or full size king for maneuverability

Yes. It can be a challenge. It helps to have a forearm forklift. Also many modern mattresses can be folded like a taco. If you get a bed in a box, you can haul it in and have it expand in place. It also helps to protect it with plastic or a mattress bag.

split king bed experience? Good or bad?
I love my split king. I sleep better and we keep a few inch gap on our adjustable frames. I ruin mattresses and she doesn't.. I bought a 4.6k intellibed midnight and she is still on last year's purple 4 and my old one is in the trash. For sex it kinda sucks but I'd rather sleep perfectly then worry about that. My wife is a crazy sleeper. And now I sleep better without disturbance. More on reddit.com
