King vs. Split King Bed: Which One is Right For You? - Lucid
August 21, 2023 - The short answer, not much. But a few minor differences can make or break your happiness in the bedroom. Both King and Split King beds measure 76” wide x 80” long, so they are the exact same size and can fit into the same King size bed frame.

Split King vs Full King adjustable frame on King Mattress
When you say split king you mean two twinxl? Making sure because some companies sell bases that are split only at the head. If it’s two twinxl I’d go that route. Usually that’s more expensive. If anything it will be more solid than one king frame. With two twin xl you will have 4 motors. One for each head and one for each foot. The king frame might only use two motors. Plus you have the flexibility to go twinxl mattress in the future. More on reddit.com

Pros and Cons of a Split King
Bought a split Cali king this summer with a L&P adjustable base. Highly recommended for sleeping. Can't be beat. Terrible for everything other than sleeping. Tile floors. I failed to fully appreciate an adjustable split king is literally two separate beds pushed up against each other and nothing anchors the two together. Mind the gap. Def a no-go if you're a frequent spooner. You might have better luck on carpet or a traditional frame. Even on a traditional frame, though, the gap between the two mattresses won't meet perfectly and seal. It will always be there like the cushions on a couch. Good luck! More on reddit.com

Tempur King or Split King Base?
If you have one mattress and don't plan to do the split king (two txl mattresses) in the future the one piece is going to be better value. If you ever move it is much easier to deal with the split king base, just as something to keep in mind but functionally there shouldn't be much of a motion transfer difference - they'd both offer strong grounding and Tempurs already eat motion.

July 25, 2023 - The only problem is half-Cal-King bedding is really difficult to find for the split mattress. Half of a King is a Twin XL, which is pretty common, but half of a Cal King is Twin XXL, or "hospital bed" size, which seems a lot rarer.

The answer is no. Split kings are actually two twin XL mattresses arranged side-by-side to create a single larger bed. It’s the same size as a traditional king bed, but with the added customization options.
